TY - JOUR. T1 - Systemic therapy of disseminated myeloma in passively immunized mice using measles virus-infected cell carriers. AU - Liu, Chunsheng. AU - Russell, Stephen J.. AU - Peng, Kah Whye. PY - 2010/6. Y1 - 2010/6. N2 - Multiple myeloma (MM) is bone marrow plasma cell malignancy. A clinical trial utilizing intravenous administration of oncolytic measles virus (MV) encoding the human sodium-iodide symporter (MV-NIS) is ongoing in myeloma patients. However, intravenously administered MV-NIS is rapidly neutralized by antiviral antibodies. Because myeloma cell lines retain bone marrow tropism, they may be ideal as carriers for delivery of MV-NIS to myeloma deposits. A disseminated human myeloma (KAS 6/1) model was established. Biodistribution of MM1, a myeloma cell line, was determined after intravenous infusion. MM1 cells were found in the spine, femurs, and mandibles of tumor-bearing mice. Lethally irradiated MM1 cells remained susceptible to measles infection and transferred MV to KAS 6/1 ...
Upon the addition of antibody to measles virus, measles virus antigens expressed on the surface of infected cells can be modulated from the cells membrane in vitro. Removal of measles virus antigens from the surface of cells occurs relatively rapidly and is accompanied by a parallel reduction in the ability of antibody and complement to lyse these cells. Modulation of surface viral antigens can occur in the absence of cap formation and is fully reversible once measles virus antibodies are removed from culture medium. Protracted exposure of acutely infected cells to measles virus antibodies results in a population of cells that exhibit normal cytomorphology and growth behavior. These cells continue to express measles virus antigens internally, but not at the cell surface, and are refractory to immune lysis. Once antiviral antibody is removed, measles virus antigens again appear on the cell surface, giant cell and syncytial formation occur, and cell death follows. These observations may explain ...
We report a case of monozygotic twins whose mother was infected with measles at 19 weeks gestation. One of the twins died in utero at 32 weeks gestation. The placenta of the stillbirth showed massive fibrin deposition, and some residual trophoblasts contained many inclusion bodies positive for measles virus antigen. Fetal organs and cells other than a few splenic lymphocytes showed no evidence of measles virus infection. The placenta of the surviving infant showed focal intervillous fibrin deposits, and only a few syncytiotrophoblasts were positive for measles virus antigen. At present, 7 months after the delivery, the surviving infant has not developed any sign of measles virus infection. Postpartum course of the mother has been uneventful, although high titers of serum anti-measles virus IgM persisted for 6 months after delivery. This case is informative in the following respects: the villous trophoblasts had diagnostic inclusion bodies and ultrastructural evidence of measles virus infection, the
Analysis of urine specimens by using reverse transcriptase-PCR was evaluated as a rapid assay to identify individuals infected with measles virus. For the study, daily urine samples were obtained from either 15-month-old children or young adults following measles immunization. Overall, measles virus RNA was detected in 10 of 12 children during the 2-week sampling period. In some cases, measles virus RNA was detected as early as 1 day or as late as 14 days after vaccination. Measles virus RNA was also detected in the urine samples from all four of the young adults between 1 and 13 days after vaccination. This assay will enable continued studies of the shedding and transmission of measles virus and, it is hoped, will provide a rapid means to identify measles infection, especially in mild or asymptomatic cases.. ...

Zhang X., Lu G., Qi J., Li Y., He Y., Xu X., Shi J., Zhang C.W., Yan J., Gao G.F.. Measles virus is a major public health concern worldwide. Three measles virus cell receptors have been identified so far, and the structures of the first two in complex with measles virus hemagglutinin (MV-H) have been reported. Nectin-4 is the most recently identified receptor in epithelial cells, and its binding mode to MV-H remains elusive. In this study, we solved the structure of the membrane-distal domain of human nectin-4 in complex with MV-H. The structure shows that nectin-4 binds the MV-H β4-β5 groove exclusively via its N-terminal IgV domain; the contact interface is dominated by hydrophobic interactions. The binding site in MV-H for nectin-4 also overlaps extensively with those of the other two receptors. Finally, a hydrophobic pocket centered in the β4-β5 groove is involved in binding to all three identified measles virus receptors, representing a potential target for antiviral drugs.. Nat. ...
Yilla, M.; Hickman, C.; McGrew, M.; Meade, E.; Bellini, W.J., 2003: Edmonston measles virus prevents increased cell surface expression of peptide-loaded major histocompatibility complex class II proteins in human peripheral monocytes
Measles remains a leading cause of death worldwide among children because it suppresses immune function. The measles virus (MV) P gene encodes three proteins (P, V, and C) that interfere with innate immunity, controlling STAT1, STAT2, mda5, and perhaps other key regulators of immune function. We identified here three residues in the shared domain of the P and V proteins-tyrosine 110, valine 112, and histidine 115-that function to retain STAT1 in the cytoplasm and inhibit interferon transcription. This information was used to generate a recombinant measles virus unable to antagonize STAT1 function (STAT1-blind MV) differing only in these three residues from a wild-type strain of well-defined virulence. This virus was used to assess the relevance of P and V interactions with STAT1 for virulence in primates. When a group of six rhesus monkeys (Macaca mulatta) was inoculated intranasally with STAT1-blind MV, viremia was short-lived, and the skin rash and other clinical signs observed with wild-type MV were
Summary Treatment of measles virus-infected cells with cycloheximide results in a three-fold increase of 3H-uridine incorporation into the 12 to 36S mRNA species and in the inhibition of genomic 50S RNA synthesis. Consistent with these observations was the finding of a build-up of polyribosomes but an absence of nucleocapsids in the infected cells. These results suggest that measles virus RNA replication, but not transcription, is dependent upon active protein synthesis.
The advent of live-attenuated vaccines against measles virus during the 1960ies changed the circulation dynamics of the virus. Earlier the virus was indigenous to countries worldwide, but now it is mediated by a limited number of evolutionary lineages causing sporadic outbreaks/epidemics of measles or circulating in geographically restricted endemic areas of Africa, Asia and Europe. We expect that the evolutionary dynamics of measles virus has changed from a situation where a variety of genomic variants co-circulates in an epidemic with relatively high probabilities of co-infection of the individual to a situation where a co-infection with strains from evolutionary different lineages is unlikely. We performed an analysis of the partial sequences of the hemagglutinin gene of 18 measles virus strains collected in Denmark between 1965 and 1983 where vaccination was first initiated in 1987. The results were compared with those obtained with strains collected from other parts of the world after the
We investigated the presence of the measles virus genome in order to identify asymptomatic infections in the adult population. Bone-marrow aspirates were obtained from 179 patients, 20-96 years of age, for the diagnosis of malignant diseases (29 with malignant lymphoma, 28 with acute leukaemia, 21 with myelodysplastic syndrome, five with multiple myeloma and 96 with other diseases). The measles virus genome was detected in 17 (9·5%) of 179 individuals by RT-PCR and 28 (15·6%) through hybridization. The genomes detected in bone marrow were all in the same cluster, D5, the strain circulating during the study period, and no evidence of persistent infection was obtained. We conclude that asymptomatic infections of measles virus are common in adults and the presence of the measles virus genome would not be related to the pathogenesis of illness.
Twenty-eight outbreaks in six regions and two major cities in Ethiopia from 2000 to 2004 were investigated, with the collection of 207 venous blood and/or oral fluid samples. Measles diagnosis was confirmed by detection of measles-specific IgM and/or detection of measles virus by polymerase chain reaction (PCR). Of 176 suspected cases tested for specific measles IgM, 142 (81%) were IgM positive. Suspected cases in vaccinated children were much less likely to be laboratory confirmed than in unvaccinated children (42% vs. 83%, P , 0.0001). Of 197 samples analyzed by RT-PCR measles virus genome was detected in 84 (43%). A total of 58 wild-type measles viruses were characterized by nucleic acid sequence analysis of the nucleoprotein (N) and hemagglutinin (H) genes. Two recognized genotypes (D4 and 133) were identified. Each outbreak comprised only a single genotype and outbreaks of each genotype tended to occur in distinct geographical locations. 133 was first observed in 2002, and has now been the ...
Measles virus, a paramyxovirus of the Morbillivirus genus, is responsible for an acute childhood illness that infects over 40 million people and leads to the deaths of more than 1 million people annually (C. J. Murray and A. D. Lopez, Lancet 349:1269-1276, 1997). Measles virus infection is characterized by virus-induced immune suppression that creates susceptibility to opportunistic infections. Here we demonstrate that measles virus can inhibit cytokine responses by direct interference with host STAT protein-dependent signaling systems. Expression of the measles V protein prevents alpha, beta, and gamma interferon-induced transcriptional responses. Furthermore, it can interfere with signaling by interleukin-6 and the non-receptor tyrosine kinase, v-Src. Affinity purification demonstrates that the measles V protein associates with cellular STAT1, STAT2, STAT3, and IRF9, as well as several unidentified partners. Mechanistic studies indicate that while the measles V protein does not interfere with ...
Measles virus is highly contagious. The probability of contracting the virus from an infected individual is greater than 90 percent, unless the person in question has been previously infected early in life or been vaccinated. Despite current efforts to eradicate measles, local outbreaks occur occasionally due to insufficient vaccine coverage in the general population. Germany currently lags behind the rest of Europe in its efforts to eradicate measles. In 2017, the number of measles infections in Germany increased three-fold compared to 2016, and a total of 929 cases were reported in 2017.. Measles virus, like the highly infectious canine distemper virus used in this study, belongs to the genus Morbillivirus. It is known that during infection and replication the virus interacts with the infected host using two different receptors on host cells. Measles virus first uses a receptor on immune cells during infection, replicates at this location, and then later uses a second receptor on cells in the ...

In this review, we summarize the recently determined crystal structure of the measles virus (MV) attachment protein hemagglutinin. Based on this structural information, we also discuss how the MV hemagglutinin interacts with various cellular receptors and why MV vaccines have been effective for many years without inducing escape mutant viruses. Other topics discussed are a putative MV receptor present on polarized epithelial cells and the protein expression system using a cultured human cell line 293SGnTI(-), which is suitable for X-ray crystallographic analyses..

In response to the need for prompt differentiation between vaccine reactions and wild-type measles virus infection cases, laboratories have been developing methods that do not require sequencing of N-450. A method targeting a region on the hemagglutinin gene has been described and tested with a small number of vaccine and wild-type specimens or isolates (15). Here, we describe the development and validation of a measles virus genotype A-specific RT-qPCR, MeVA RT-qPCR, that targets the N gene of MeV. This assay produces rapid results and is capable of high throughput. The MeVA RT-qPCR was thoroughly tested at three global reference laboratories. Two RT-qPCR platforms and over 300 samples were included in the evaluation. Overall, our data show very high (99.5%) specificity for the A genotype, albeit with lower (94%) sensitivity than the standard MeV RT-qPCR (16). Because of the lower sensitivity, the MeVA RT-qPCR is intended to be used as a tool for rapid detection of genotype A sequences and not ...

Targeting specific areas of the measles virus polymerase, a protein complex that copies the viral genome, can effectively fight the measles virus and be used as an approach to developing new antiviral drugs to treat the serious infectious disease, according to a study by the Institute for Biomedical Sciences at Georgia State University published in PLoS Pathogens.. Measles is a highly contagious virus that can lead to serious health complications and death. It begins with a fever, cough, runny nose and red eyes followed by a rash of tiny, red spots that starts at the head and spreads to the rest of the body. Although declared eliminated in the United States in 2000, the Centers for Disease Control and Prevention (CDC) says the U.S. is experiencing the greatest number of measles cases reported since the early 1990s.. While an effective vaccine exists, there has been a steady decline in the number of people being vaccinated against the measles virus. Most new cases were among unvaccinated ...

Although measles is a monotypic virus, 22 genotypes of wild-type virus are recognized; many genotypes have been associated with endemic circulation of measles virus in certain geographic regions or have been documented in connection with an outbreak or epidemic in an area [4, 5]. The measles vaccine virus strains belong to genotype A and can be distinguished from wild-type virus of the same genotype by means of sequence analysis [6 -8]. Analyses of measles virus sequences in brain tissue samples obtained from patients with SSPE have identified only wild-type measles virus, and the virus genotypes identified have been consistent with the genotype of measles virus that circulated in the area where the patients lived and to which the patients had been exposed ⩽10 years before the onset of symptoms of SSPE [6, 9 -13]. Genetic studies have supported epidemiologic evidence that measles vaccine virus does not cause SSPE [6, 14, 15]. In cases of SSPE that developed in children or adults who had no ...
Although virus isolation can be used to diagnose measles virus infection, a long incubation period is required to obtain results. Furthermore, viral culture is neither sensitive nor specific, and it increases the potential risk of laboratory personnel contacting this virus. Serological detection of measles virus infection is not sensitive. In some cases, measles virus can be detected by PCR in oral fluids well before the onset of IgM antibody (Oliveira et al., 2003). The ability to detect measles virus by real time PCR in a wide variety of sample types such as urine, oral fluid and CSF not only simplifies sample acquisition procedures, but also offers multiple perspectives on the diseases progression. ...

We demonstrated here in tissue culture that wild-type MV-infected human T lymphocytes are drastically impaired in their capacity to migrate through endothelial cell barriers. MV infection enhanced the adhesion of T cells to endothelial cells, and the subsequent close cell contact frequently mediated infection of the endothelial cells. The enhanced adhesion of leukocytes obviously allowed the first steps of transendothelial migration, including the formation of transmigratory cups, to take place; however, it may also be the reason why completion of the process is inhibited. Interestingly, the interaction of UV-inactivated MV with leukocytes did not inhibit transendothelial migration. This indicates that the impairment of cytoskeletal rearrangement, polarization, CD3 clustering, and cell spreading of T cells, as described earlier for a time scale of 2 h after virus-cell interaction (27), is only transient. In addition, MV infection did not strongly affect diapedesis per se. However, the capacity ...

Measles virus is a member of the genus Morbillivirus within the family Paramyxovirus. Measles virus differes from other members of the family in that it lacks neuraminidase. There is only one measles serotype, so recovery from natural infection confers lifelong immunity. Measles is one of five childhood exanthems, the others being rubella, varicella, roseola and fifth disease. Humans are the only known host for measles virus.. Epidemiology Measles is one of the most contagious human diseases. Vaccination has reduced the global incidence of measles, yet the World Health Organization reports there are still 45 million cases annually and 1.2 million deaths.. Transmission The principal mode of transmission is via large droplets of infected respiratory secretions inhaled during face-to-face exposure with coughing and sneezing individuals. This occurs during the catarrhal stage of the disease.. Pathogenesis Natural infection is initiated when measles virus reaches epithelial cells in the respiratory ...
Among infectious agents, measles virus (MV) remains a scourge responsible for 1 million deaths per year and is a leading cause of childhood deaths in developing countries. Although MV infection itself is not commonly lethal, MV-induced suppression of the immune system results in a greatly increased susceptibility to opportunistic bacterial infections that are largely responsible for the morbidity and mortality associated with this disease. Despite its clinical importance, the underlying mechanisms of MV-induced immunosuppression remain unresolved. To begin to understand the basis of increased susceptibility to bacterial infections during MV infection, we inoculated transgenic mice expressing the MV receptor, CD46, with MV and Listeria monocytogenes. We found that MV-infected mice were more susceptible to infection with Listeria and that this corresponded with significantly decreased numbers of macrophages and neutrophils in the spleen and substantial defects in IFN-γ production by CD4+ T cells. ...

Previous evidence for immune amnesia has been based on mathematical models and population-level studies according to Dr. Michael Mina, assistant professor of epidemiology at the Harvard T.H. Chan School of Public Health and the primary author of the study released this week in Science. The new studies are the first to show any of the real biology that helps explain the population-level effects, he says.. Understanding how this happens has really been a burning question, says Dr. Duane Wesemann of Harvard Medical School. Wesemann authored an article in Science Immunology explaining the significance of both studies; he was not involved in either. These two papers complement each other in an interesting way, and they both provide clues to help answer how measles causes immune damage. The two studies used blood samples collected from 77 unvaccinated children in an Orthodox Protestant community in the Netherlands, before and after the children contracted the measles virus during a local ...
Neutralizing antibodies directed against measles virus (MV) surface glycoproteins prevent viral attachment and entry through the natural receptors. in humans. At a concentration of 10 g/ml MAb 20H6 exhibited a dominant protective effect and prevented MAb CL55-mediated enhancement of MV contamination and virus-mediated fusion. These results indicate that neutralization capacity of the H-specific IgG determines the balance between antibody enhancement and protection against MV contamination in microglial cells. NAP protein (MV-s-NAP) (Iankov et al., 2011) were amplified on Vero cells. Viral stocks were prepared using repeated freezing-thawing procedure and computer virus titer was decided in both plaque-forming models (PFU) or tissue culture IKK-2 inhibitor VIII infectious doses 50% (TCID50) per ml (Iankov et al., 2011).

Two hallmarks of measles virus (MV) infection are the ability of the virus to cause immunosuppression and the resultant enhanced susceptibility of the infected host to microbial insults. We investigated the effect of MV infection on the ability of dendritic cells (DCs) to induce IL-12 via toll-like receptor (TLR) signaling. When infected with MV, transgenic mice which expressed human SLAM receptor on their DCs were defective in the selective synthesis of IL-12 in DCs in response to stimulation of TLR4 signaling, but not to engagements of TLR2, 3, 7 or 9. MV suppressed TLR4-mediated IL-12 induction in DCs even in the presence of co-stimulation with another ligand for TLR2, 3, 7, or 9. While MV V and C proteins were not responsible for IL-12 inhibition, interaction of MV hemagglutinin with human SLAM facilitated the suppression. These results suggest that MV, by altering DC function, renders them unresponsive to secondary pathogens via TLR4 ...
Globally eliminating measles using available vaccines is biologically feasible as the measles virus (MV) hemagglutinin (H) protein is antigenically stable. epitope. When MV-H forms a tetramer (dimer of dimers) these epitopes may type the dimer-dimer user interface and among the two epitopes could also connect to the F proteins.

We recently reported that measles virus nucleocapsid protein (MVNP) plays a key role in the development of these abnormal osteoclasts. MVNP can induce the pagetic osteoclast phenotype in vitro and in vivo in TRAP-MVNP transgenic mice. However, the molecular mechanisms by which MVNP generates pagetic osteoclasts have not been determined. TANK-binding ...

TY - JOUR. T1 - Measles virus and the nervous system. AU - Griffin, Diane. PY - 2014. Y1 - 2014. N2 - Measles is a highly contagious viral disease caused by an enveloped negative-strand RNA virus in the Paramyxovirus family. Measles is associated with three different types of neurologic complications: acute disseminated encephalomyelitis (ADEM), measles inclusion body encephalitis (MIBE), and subacute sclerosing panencephalitis (SSPE). ADEM is a monophasic autoimmune demyelinating disease that has an incidence of 1:1000 and occurs primarily in children over the age of 4 years. Disease onset is acute and usually occurs within days to weeks after measles. Pathology is characterized by perivenular inflammation and demyelination. MIBE is due to progressive measles virus infection of the nervous system and occurs in immune-compromised individuals who are unable to clear virus after infection. Disease onset is subacute and usually fatal. Pathology shows nuclear and cytoplasmic viral inclusion bodies ...

Measles, caused by measles virus (MeV), is a common infection in children. MeV is a member of the genus Morbillivirus and is most closely related to rinderpest virus (RPV), which is a pathogen of cattle. MeV is thought to have evolved in an environment where cattle and humans lived in close proximity. Understanding the evolutionary history of MeV could answer questions related to divergence times of MeV and RPV. We investigated divergence times using relaxed clock Bayesian phylogenetics. Our estimates reveal that MeV had an evolutionary rate of 6.0 - 6.5 × 10-4 substitutions/site/year. It was concluded that the divergence time of the most recent common ancestor of current MeV was the early 20th century. And, divergence between MeV and RPV occurred around the 11th to 12th centuries. The result was unexpected because emergence of MeV was previously considered to have occurred in the prehistoric age. MeV may have originated from virus of non-human species and caused emerging infectious diseases around the
Herein we report the outbreak of measles caused by the genotype D8 measles virus (MeV) for the first time in Jiangsu province in China, which was possibly imported by a foreign student from Laos. Throat swab specimens were collected and used to isolate the virus. A 634-bp fragment of the N gene and 1854-bp fragment of H gene were amplified by reverse transcription-PCR and sequenced, respectively. Phylogenetic results indicated that they belonged to genotype D8 MeV. Further epidemiological investigation showed that adults with D8 MeV infection had not been vaccinated against measles. In China, almost all cases of D8 genotype MeV infection occurred in patients with no previous measles vaccination. Therefore, it is necessary to offer measles vaccination for adults who are immunized.. Countries all over the world have adopted goals for measles elimination by or before 2020.1 Toward that end, China government implemented measles supplementary immunization activity in the whole country in 2010, and ...
Neon Nettle - Warning Issued in the US as Deadly Measles Virus Spreads Through Airports - Government health official warn parents to get children vaccinated
What is Measles?. Measles is a vaccine-preventable, highly communicable (easy to spread) disease caused by the measles virus. The reason why measles is so contagious is because the virus is easily spread through the air, by coughing and sneezing, as well as direct contact with an infected person [1]. The incubation period (time from exposure to first symptom) for measles is about 10 days. The characteristic measles rash appears within about 14 days following exposure. Individuals with measles are infectious from approximately 4 days before rash onset until 4 days after the rash appears. According to the CDC Measles is so contagious that if one person has it, 90% of the people close to that person who are not immune will also become infectious [3]. Consequently, anyone who has not had measles or been successfully immunized is susceptible to the disease. About 30% of measles cases result in complications, such as pneumonia, diarrhea, and ear infections [1,2].. Re-Emergence of Measles in the ...

Measles is a very contagious disease caused by a virus that grows in the cells in the back of the throat and lungs. The symptoms of measles generally begin about 7-14 days after a person is infected, and typically include a blotchy rash (usually begins on a persons face at the hairline and spreads down to the feet), fever, cough, runny nose, red and watery eyes, feeling run down and achy, and tiny white spots with bluish-white centers found inside the mouth. Measles photos can be found on the CDC website.. Measles spreads when a person infected with the measles virus breathes, coughs, or sneezes. People can catch measles just by being in a room where an infected person has been, even up to 2 hours after that person is gone. Almost everyone who has not been vaccinated will get measles if they are exposed to the measles virus.. Measles can be very serious and can cause complications including blindness, encephalitis (brain swelling that could result in deafness or mental retardation), severe ...
A nation-wide measles outbreak occurred in 1988 in Taiwan. A retrospective cohort study was conducted to define the protective titre of measles neutralising (NT) antibody. Paired sera collected in 1987 and 1988 were available from 190 individuals born in 1984 who had participated in an annual hepatitis B immunisation follow-up from 1986 to 1991. Measles NT titres were quantified using a standardised neutralisation enzyme immunoassay. Measles infection was defined as a greater than or equal to4-fold rise in NT titre or seroconversion between paired sera. Symptomatic measles infection was ascribed to individuals who had measles infection and who reported measles-like symptoms between 1987 and 1988. Results demonstrated a dose-response relationship between pre-exposure NT titres and protection against measles infection. 47 of 48 individuals with measles infection in 1988 had preexposure NT titres less than or equal to1,017 mlU/ml; all 12 symptomatic cases had pre-exposure NT titres less than or ...
In a previous study we demonstrated that vesicular stomatitis virus (VSV) can be used as a vector to express a soluble protein in mammalian cells. Here we have generated VSV recombinants that express four different membrane proteins: the cellular CD4 protein, a CD4-G hybrid protein containing the ectodomain of CD4 and the transmembrane and cytoplasmic tail of the VSV glycoprotein (G), the measles virus hemagglutinin, or the measles virus fusion protein. The proteins were expressed at levels ranging from 23-62% that of VSV G protein and all were transported to the cell surface. In addition we found that all four proteins were incorporated into the membrane envelope of VSV along with the VSV G protein. The levels of incorporation of these proteins varied from 6-31% of that observed for VSV G. These results suggest that many different membrane proteins may be co-incorporated quite efficiently with VSV G protein into budding VSV virus particles and that specific signals are not required for this ...
Eliminate the disease from the U.S. with sufficient and ongoing vaccination efforts.. This year there have been more reported cases of measles in the United States than in any year in recent memory. Wasnt measles eliminated from the United States in 2000? If so, why are we seeing so many cases this year?. The reason is that measles is still quite common in other parts of the world. The measles outbreaks this year happened because non-immune persons contracted measles infection while traveling abroad, and then spread measles to others when they returned to the U.S. Measles is a virus that causes a fever illness associated with rash, and may infect other organs, such as the lungs (pneumonia) and brain (encephalitis), sometimes leading to death.. Measles is very contagious. It infects up to 90 percent of non-immune people who come in contact with it. The measles virus can remain suspended in the air for two hours after an infected person leaves a room, infecting others without direct ...
Measles is a highly contagious respiratory disease caused by the measles virus. The disease is also called rubeola. Measles causes fever, runny nose, cough and a rash all over the body. About one out of 10 children with measles also gets an ear infection, and up to one out of 20 gets pneumonia. For every 1,000 children who get measles, one or two will die. Adults can also get measles especially if they are not vaccinated. Children under 5 years of age and adults over 20 are at higher risk for measles complications including pneumonia, and a higher risk of hospitalization and death from measles than school aged children and adolescents. Other rash-causing diseases often confused with measles include roseola (roseola infantum) and rubella (German measles).. ...
These times include the period when the individual was at the location and two hours after. Measles virus can remain in the air for up to two hours after someone infectious with measles leaves the area. Anyone who was at these locations during the times listed could have been exposed to measles. What to do if you were in a location of potential measles exposure Most people in our area have immunity to the measles through vaccination, so the risk to the general public is low. However anyone who was in the locations of potential exposure to measles around the times listed below should: • Find out if you have been vaccinated for measles or have had measles previously. Make sure you are up-to-date with the recommended number of measles (MMR) vaccinations. • Call a healthcare provider promptly if you develop an illness with fever or illness with an unexplained rash. To avoid possibly spreading measles to others, do not go to a clinic or hospital without calling first to tell them you want to be ...
Last month there was a measles outbreak in the Waikato, with students at both Fairfield College and Morrinsville College reported as having contracted the disease. The outbreak now appears to have spread to the South Island after a teenager, who recently visited Hamilton, also contracted the disease.. Measles is highly contagious; however it is also easily preventable. Two doses of the measles vaccine, MMR, will provide protection for you and your family. Anyone, from babies through to adults, who are not fully immunised are at risk of contracting the virus. Adults born prior to 1969 are less at risk as they were probably exposed to measles as a child and therefore have a natural immunity. Those with low immune systems are at a higher risk.. The measles virus is easily spread through the air by breathing, sneezing and coughing. You will not necessarily be aware that you have contracted the disease until you feel sick, however you will be infectious for 5 days before and 5 day after the symptoms ...
We investigated the genetic diversity of measles virus (MV) in Nigeria (2004-2005) and the Democratic Republic of the Congo (DRC) (2002-2006). Genotype B3 strains circulating in Kinshasa, DRC, in 2002-2003 were fully replaced by genotype B2 in 2004 at the end of the second Congo war. In Nigeria (2004-2005), two genetic clusters of genotype B3, both of which were most closely related to 1 variant from 1998, were identified. Longitudinal analysis of MV strain diversity in Nigeria suggested that only a few of the previously described 1997-1998 variants had continued to circulate, but this finding was concomitant with a rapid restoration of genetic diversity, probably caused by low vaccination coverage and high birth rates. In contrast, the relatively low genetic diversity of MV in DRC and the genotype replacement in Kinshasa reflect a notable improvement in local measles control ...
Following the RTS,S malaria vaccine, which showed only partial protection with short-term memory, there is strong support to develop second-generation malaria vaccines that yield higher efficacy with longer duration. The use of replicating viral vectors to deliver subunit vaccines is of great interest due to their capacity to induce efficient cellular immune responses and long-term memory. The measles vaccine virus offers an efficient and safe live viral vector that could easily be implemented in the field. Here, we produced recombinant measles viruses (rMV) expressing malaria gold standard circumsporozoïte antigen (CS) of Plasmodium berghei (Pb) and Plasmodium falciparum (Pf) to test proof of concept of this delivery strategy. Immunization with rMV expressing PbCS or PfCS induced high antibody responses in mice that did not decrease for at least 22 weeks post-prime, as well as rapid development of cellular immune responses. The observed long-term memory response is key for development of ...
The MMR vaccine has been linked to autism, Crohns disease, inflammatory bowel disease[142,143] and other serious chronic stomach problems[144], epilepsy, brain damage including meningitis[145,146], cerebral palsy, pancreatitis[147] and diabetes mellitus[148-150], encephalopathy, encephalitis[151,152], hearing and vision problems, arthritis, behavioural and learning problems, chronic fatigue syndrome, diabetes, Guillain-Barre syndrome, idiopathic thrombocytopaenic purpura, subacute sclerosing panencephalitis (SSPE), leukaemia, multiple sclerosis, and death.. There is evidence that in cases of immune deficiency that viruses continue to persist in the body[143,153-155]. The measles virus is known to persist in patients with subacute sclerosing panencephalitis (SSPE), measles inclusion body encephalitis (MIBE)[156] and multiple sclerosis[157]. Since the introduction of measles vaccines, vaccine-associated SSPE has increased in the USA. Furthermore patients with B or T-cell immunodeficiencies have ...
Measles is once again capturing headlines in the United States. Even though only a small portion of the U.S. population is susceptible, international travel, vaccine refusal or delay, and rare vaccine failures combined with high social contacts allow the highly infectious measles virus to infect susceptible individuals of all ages (1). The story of an unvaccinated child or adolescent contracting measles while traveling abroad and transmitting the virus to others upon return to the United States has been repeated many times in recent years. The 2014-2015 Disneyland-associated outbreak has captured public attention because infants too young to receive the vaccine and children with true medical contraindications to vaccination became infected (2). In addition, Disneyland employees contracted measles and possibly contributed to disease transmission. In 2014, there were 23 measles outbreaks and more than 644 cases of measles (2). More outbreaks owing to vaccine refusal will undoubtedly occur because ...
Northern Voices Online reports, Public Health officials are actually trying to figure out as to how the woman was exposed to measles. Although her immunization status has not been disclosed, Toronto Public Health spokesperson Jennifer Veenboer said, Were continuing to investigate all aspects of this latest case as we have been with all the other cases.. The measles virus causes a fever, rash, cough, red watery eyes and a runny nose. The red rash starts on the face and spreads to the rest of the body. Most people with measles are sick for up to 10 days and then recover completely. Symptoms are more severe for infants and adults. Measles can lead to ear infections, lung infection (pneumonia), an infection of the brain (encephalitis), and death. Pregnant women with measles can have premature delivery and miscarriages. Measles does not cause birth defects.. Measles is easily spread when an infected person coughs or sneezes, spreading droplets that contain the virus into the air. Less commonly, ...
measles; ; Measles is a serious illness caused by a virus and it is very contagious - very easily spread to other people. It is usually spread by droplets (through coughing, sneezing, runny nose, or runny eyes). Children in Australia are immunised against measles at 12 and 18 months. (There is more about this in the Childhood Immunisation Program on the SA Health website). A child or adult who has not been immunised is very likely .to catch it if exposed to a person who has measles. Measles has been brought into Australia by international travellers, and could spread easily among people who have not been immunised.. Measles is not just one of the things that children catch and get over. Children often get very sick with measles and they can have serious health problems and even die. Adults can also become very unwell if they get measles.. ...
Measles is one of the most contagious diseases ever known. It causes death and disability among young children across the world. When someone has measles almost everyone they come into contact with will catch measles too - unless they are immunised. Because measles is so infectious lots of people can become ill with measles very quickly, this is called an epidemic.. Measles is a disease that can make you very ill and weak, cause you to lose your sight and may even kill you, especially if you havent had enough food to grow strong. When children are malnourished or weak measles is even more dangerous. Measles can make children vulnerable to other diseases, like diarrhoea, ear and eye infections, respiratory illnesses, and these may cause disabilities including blindness or death.. ...
Why was measles considered an obligatory illness for a child? What is the danger of measles for a child? Are there guarantees against serious complications? Under what conditions can measles be defeated?. Disease of unique spread - this is what measles was called by the largest Soviet epidemiologist L. V. Gromashevsky. Precisely because susceptibility to measles is almost one hundred percent, few have managed to avoid this infection in childhood. So there was an idea that every child should transfer measles, What should not be avoided, the parents thought. And did not seek to protect the child from measles. In ancient times, there was even a custom: if one child fell ill in a family, healthy people were put to bed next to him in order to get off at once.. Against the background of other deadly infections that were widespread at that time, measles might perhaps have seemed harmless. But it does not always end happily. According to world statistics, in the 60s of our century every year on ...
Dr. David Brownstein in his blog tells a story of Measles that should ease parents fears.. From 1969-1974, the Brady Bunch ran weekly as a sitcom. I watched every episode and can still recall most of them. The Brady Principle refers to the episode where all six Brady kids became ill with the measles. What happened to the Brady kids? They stayed home from school, played Monopoly, and Alice cooked for them, and they recovered from the measles infection.. During the episode, Marsha Brady stated, If you have to get sick, sure cant beat the measles. The Brady Principle would indicate that measles is not a dangerous disease for most who become ill from it. When I was a child, measles was treated as an illness similar to chickenpox; most children became ill with these childhood diseases and most recovered uneventfully. Back then, measles and chickenpox were not feared illnesses in the U.S.. Back to the Bradys. The good news for the Brady kids, and the Somali children, is that they will have ...
Background: Measles is a highly contagious virus that lives in the nose and throat mucus of an infected person. It can spread to others through coughing and sneezing. Measles can live for up to 2 hours in an airspace where the infected person coughed or sneezed. Measles is so contagious that if one person has it 90% of the people close to that person who are not immune will become infected. Infected individuals can spread measles to others from 4 days before through 4 days after the rash appears. Measles infection is a vaccine-preventable illness.. The average incubation period for measles is 10-12 days (range: 7-21 days) from the date of the initial exposure until early signs and symptoms appear.. · Early signs and symptoms of measles starts with fever (as high as 105°F) and malaise associated with cough, coryza (runny nose) and conjunctivitis (red/watery eyes), colloquially the three Cs ...
State Health Officials are now investigating six measles cases among unvaccinated people in Ellis County. The Texas Department of State Health Services is advising health care providers in the area to take precautions and consider measles as a possible diagnosis in patients with a fever and rash in addition to a cough, runny nose or conjunctivitis. The highly contagious nature of measles means its possible more cases will occur in the community. People involved in the outbreak have connections to Waxahachie and Midlothian.. DSHS first notified the public on Friday of possible measles exposures after a contagious person attended the ShowBiz Cinemas in Waxahachie on Tuesday, Jan. 9. Five additional cases have been reported since; none of them are connected to the movie theater. People who went to the theater on that day should continue to monitor themselves for measles symptoms through Jan. 30.. It usually takes about two weeks from the time someone is exposed to the measles virus for a rash to ...
The extremely high risk for measles among infants whose mothers developed measles after delivery occurred because these mothers had no maternal antibody to transfer during pregnancy. Lennon and Black1 found that 4.6% of women born after 1959 had no detectable antibody for measles, compared with 1.3% of older women. An increased proportion of infants who lack maternal antibody at birth may be one cause of increased measles susceptibility among infants of mothers born after 1963. Infants who receive no maternal antibody are susceptible to measles from birth until they are vaccinated or infected with the measles virus.. Our study has several limitations. The medium-sized dataset was sufficient to demonstrate the effect of maternal year of birth, while controlling for important potentially confounding variables, but there were not enough infants to perform subgroup analyses, such as determining the effect of the maternal year of birth in different age groups of infants. In addition, because we were ...
We have analyzed the suitability and potential of Oral Fluid (OF) to substitute serum in estimating measles IgG antibodies, during community surveys, by comparing the Optical Density (OD) of measles IgG antibodies in OF and serum of 100 apparently asymptomatic children. IgG antibody status was determined using commercially available . Measles IgG Capture ELISA. Sensitivity 89.5%, specificity 90.6% Concordance of 89%, coefficient of correlation r is equal to 0.97 (Karl Pearsons) and rho is equal to 0.86 (Spearmans), was found between OD value of OF and serum. The study emphasizes the potential of OF to surrogate serum in estimating Measles IgG antibody among children. The OF collection is advantageous over blood as it is painless. It is suitable for non-technical staff, easy to transport and less bio-hazardous ...
What is Breaking Out? Measles is a highly contagious virus that lives in the nose and throat mucus of an infected person. It can spread to others through coughing and sneezing. Measles virus can live for up to two hours in an airspace where the infected person coughed or sneezed. If other people breathe the contaminated air or touch the infected surface, then touch their eyes, noses, or mouths, they can become infected. Measles is so contagious that if one person has it, 90% of the people close to that person who are not immune will also become infected.. Measles starts with fever, runny nose, cough, red eyes, and sore throat. Its followed by a rash that spreads over the body. Infected people can spread measles to others from four days before through four days after the rash appears.. Particularly in malnourished children and people with reduced immunity, measles can cause serious complications, such as pneumonia (infection of the lungs) and encephalitis (swelling of the brain). Very rarely, ...
These photos of measles and people with measles show the measles skin rash, koplik spots, and the measles virus under a microscope.
The effect on growth in Papua New Guinea wasnt positive.. What other evidence is there, besides the fact that we know that folks with measles need a lot of extra energy while they are recovering from their infection, so likely dont have a lot leftover for a growth spurt?. Theres the fact that precocious puberty can be a complication of some infections, including measles. What happens if your child has precocious or early puberty? An early growth spurt? Yes, actually, but then they stop growing earlier than they should and they end up being shorter than their genetic potential.. Some more indirect evidence against any kind of extra growth spurt from a natural measles infection is that the mean height of young adults today, most of whom were vaccinated and didnt have measles, isnt that different from those measured in the 1960s and early 1970s.. ...
Fortunately, most people in this region have been vaccinated. When a person has been vaccinated as recommended, the vaccine is up to 97 percent effective in preventing measles. Most people at risk in the current outbreak are those who have not been vaccinated. Those who have been vaccinated or have had the measles earlier in their lives are generally not at risk.. If you think you or your child might have symptoms of measles call your doctor right away, especially if you have been exposed to someone with active measles. Your doctor will let you know if you need to come in for a visit. Measles is very contagious, which means you could give it to someone, even in a waiting room. Its important before you go in, to tell your doctor or other medical professional, that you have symptoms of measles. They will give you instructions for what to do so you do not spread it further.. Stay home if you have the measles. Dont go to school, work, to the store or to other peoples homes. Dont have visitors to ...
On the darkest day of 2018, the winter solstice, we at the Center for Vaccine Research at the University of Pittsburgh tweeted, with despair, a report in the Guardian that measles cases in Europe reached the highest number in 20 years.. Why was this a cause for concern? Europe is far away from the United States, and as some people apparently believe, measles is a benign, childhood disease that causes a bit of a rash, a dribbling nose, and a few spots, right? What was all the fuss about?. Well, as George Santayana said, Those who cannot remember the past are condemned to repeat it. Collective amnesia about the virulence of this disease has driven us to forget that measles virus has killed tens of millions of infants throughout history. Now, with several ongoing outbreaks across our own country, this unnecessary threat is back.. See also: Anti-Vaccine Hotspot Near Portland Declares Emergency as Measles Cases Rise.

Define hemorrhagic measles. hemorrhagic measles synonyms, hemorrhagic measles pronunciation, hemorrhagic measles translation, English dictionary definition of hemorrhagic measles. n. See black measles
Measles is a disease caused by the highly infectious measles virus (MeV) that results in both viremia and lymphopenia. Lymphocyte counts recover shortly after the disappearance of measles-associated rash, but immunosuppression can persist for months to years after infection, resulting in increased incidence of secondary infections. Animal models and in vitro studies have proposed various immunological factors underlying this prolonged immune impairment, but the precise mechanisms operating in humans are unknown. Using B cell receptor (BCR) sequencing of human peripheral blood lymphocytes before and after MeV infection, we identified two immunological consequences from measles underlying immunosuppression: (i) incomplete reconstitution of the naïve B cell pool leading to immunological immaturity and (ii) compromised immune memory to previously encountered pathogens due to depletion of previously expanded B memory clones. Using a surrogate model of measles in ferrets, we investigated the clinical ...

The Ministry of Health wishes to advise members of the public that there are no local or imported cases of measles in the country. As stated by the Health Minister, Dr. Christopher Tufton in responding to queries in parliament on Tuesday, April 23, there was a patient treated recently at a local private hospital for complications thought to be as a result of a recent measles infection experienced before visiting Jamaica. At the time of stay in Jamaica, the person was several days out of the infectious period for measles. After investigations, the Public Health Department concluded that neither the patient nor relatives were having measles. Precautions were taken however to ensure that all whom came in contact with the patient were immunized against measles even while the investigation was being conducted.. Jamaica has a robust surveillance system in place for fever and rash and all cases are reported within 24 hours, while suspected measles are reported immediately. The Ministry of Health does ...
On that FB thread about dropping vaccination rates in New Zealand, one commenter proudly proclaimed that she and her four children had all had measles. Over in a week, no problems, stop yer whining. Well, lovely for her - and if the illness indeed lasted only a week per person then they were lucky; 7-10 days is the norm for uncomplicated measles. But measles infection carries a range of costs and risks, about which she seemed blissfully ignorant. Or couldnt care less; on that thread, it was hard to tell sometimes. If a child comes down with measles, someone has to stay home (or pay someone else to stay home) and care for them, for a week or more. For many families, thats quite a financial burden. If any individual comes down with measles, theres a taxpayer cost, because their contacts need to be traced, checked, asked to quarantine themselves if infected. If that individual develops any of the severe complications of measles (and the risks of that are much greater than the risks associated with
In a recent Israeli study, exposure to measles virus was shown to be associated with an increased risk for Crohns disease [3]. In addition, measles virus (including vaccine-strain virus) has been amplified and sequenced from intestinal tissues of children with inflammatory bowel disease [4]. However, in the etiology of inflammatory bowel disease, it is likely that it is the pattern of exposure to measles that is more important than exposure per se. Of interest in the Davis study, therefore, was the observation of an association between age at exposure to an MCV (excluding MMR) and the type of inflammatory bowel disease that develops [1]. This observation is entirely consistent with previously reported data, and supports a role for atypical measles virus infection in the etiology of inflammatory bowel disease. Such a claim should not be made lightly, and therefore it is worth reviewing the background to this thesis, that has been described in detail elsewhere [5]-[7]. Age at exposure to natural ...
In the past few years, several endemic outbreaks of measles have been recognised, not only in children but also in adults, with severe and, occasionally, even fatal complications, possibly due to delayed diagnosis of the disease in adult medicine and decreasing vaccination rates. Furthermore, the treatment consists of supportive measures only. We present a case of severe measles pneumonitis in a 42-year-old man, a travel returnee, proven by direct virus isolation with PCR from bronchoalveolar lavage fluid. CT findings and pulmonary function testing revealed features of obstructive bronchiolitis; the patient was successfully treated with corticosteroids. He fully recovered, and lung function measurement returned to normal values. We conclude that acute measles can present as obstructive bronchiolitis and may be successfully treated with corticosteroids. ...
Scientists in the United States have found that measles causes long-term damage to the immune system, leaving people vulnerable to other infections.. The study published online on Thursday in the journal Science showed that the measles virus cancels part of the immune systems memory in both humans and ferrets.. An analysis of blood from 77 unvaccinated children before and after a measles outbreak swept through their Netherlands community revealed that the virus eliminated between 11 and 73 percent of the childrens protective antibodies, including those from influenza to herpesvirus to bacteria that cause pneumonia and skin infections.. Those antibodies are the blood proteins that remember past encounters with viruses and help the body avoid repeat infections. Without those antibodies, children lose much of their immune defenses and become vulnerable to viruses theyve already met and conquered.. The study was published simultaneously with a paper by a separate team in Science Immunology that ...
Measles infections are climbing rapidly, and public health experts are sounding the alarm. Heres what to know about why measles infections are increasing.
Measles can be distressing for those with the infection and can cause serious complications such as pneumonia and encephalitis (inflammation of the brain).. Queensland Health recommends anyone born during or since 1966, who has not had two documented doses of measles, mumps, rubella (MMR) vaccine or had proven measles, should visit their family doctor to get vaccinated for measles. The vaccine is free for anyone who requires it.. We encourage people to check if they need to be vaccinated against measles, Dr Smith said.. The initial symptoms of measles include fever, lethargy, runny nose, moist cough and sore and red eyes. This is followed a few days later by a blotchy red rash. The rash often starts on the face then becomes widespread.. Symptoms usually start around 10 days after infection but sometimes longer. Anyone who develops measles-like symptoms should isolate themselves from school, work and social activities and seek medical advice.. Its very important to call the medical practice ...
What do measles look like? Both the common (red) measles and german measles have similar looking rashes. In spite of the similar names they are caused by different viruses. Detailed description of the measles rash and measles pictures included. Measles is sometimes misspelled as measels.
Measles is a very serious disease. About one out of 10 children with measles also gets an ear infection, and up to one out of 20 gets pneumonia. One or two out of 1,000 die from measles complications. Measles can also cause pregnant woman to miscarry or give birth prematurely. Complications from measles are very common among children younger than five and adults older than 20.. Measles spreads so easily that anyone who is exposed to it and is not immune (for example, someone who has not been vaccinated) will probably get the disease.. ...
