Arbovirus infections. Medical search

Infections caused by arthropod-borne viruses, general or unspecified.

Arthropod-borne viruses. A non-taxonomic designation for viruses that can replicate in both vertebrate hosts and arthropod vectors. Included are some members of the following families: ARENAVIRIDAE; BUNYAVIRIDAE; REOVIRIDAE; TOGAVIRIDAE; and FLAVIVIRIDAE. (From Dictionary of Microbiology and Molecular Biology, 2nd ed)

Encephalitis caused by neurotropic viruses that are transmitted via the bite of TICKS. In Europe, the diseases are caused by ENCEPHALITIS VIRUSES, TICK-BORNE, which give rise to Russian spring-summer encephalitis, central European encephalitis, louping ill encephalitis, and related disorders. Powassan encephalitis occurs in North America and Russia and is caused by the Powassan virus. ASEPTIC MENINGITIS and rarely encephalitis may complicate COLORADO TICK FEVER which is endemic to mountainous regions of the western United States. (From Joynt, Clinical Neurology, 1996, Ch26, pp14-5)

Infections of the brain caused by arthropod-borne viruses (i.e., arboviruses) primarily from the families TOGAVIRIDAE; FLAVIVIRIDAE; BUNYAVIRIDAE; REOVIRIDAE; and RHABDOVIRIDAE. Life cycles of these viruses are characterized by ZOONOSES, with birds and lower mammals serving as intermediate hosts. The virus is transmitted to humans by the bite of mosquitoes (CULICIDAE) or TICKS. Clinical manifestations include fever, headache, alterations of mentation, focal neurologic deficits, and COMA. (From Clin Microbiol Rev 1994 Jan;7(1):89-116; Walton, Brain's Diseases of the Nervous System, 10th ed, p321)

A collection of single-stranded RNA viruses scattered across the Bunyaviridae, Flaviviridae, and Togaviridae families whose common property is the ability to induce encephalitic conditions in infected hosts.

A family of the order DIPTERA that comprises the mosquitoes. The larval stages are aquatic, and the adults can be recognized by the characteristic WINGS, ANIMAL venation, the scales along the wing veins, and the long proboscis. Many species are of particular medical importance.

A syndrome that is associated with microvascular diseases of the KIDNEY, such as RENAL CORTICAL NECROSIS. It is characterized by hemolytic anemia (ANEMIA, HEMOLYTIC); THROMBOCYTOPENIA; and ACUTE RENAL FAILURE.

A disease caused by potent protein NEUROTOXINS produced by CLOSTRIDIUM BOTULINUM which interfere with the presynaptic release of ACETYLCHOLINE at the NEUROMUSCULAR JUNCTION. Clinical features include abdominal pain, vomiting, acute PARALYSIS (including respiratory paralysis), blurred vision, and DIPLOPIA. Botulism may be classified into several subtypes (e.g., food-borne, infant, wound, and others). (From Adams et al., Principles of Neurology, 6th ed, p1208)

Intestinal infection with organisms of the genus CRYPTOSPORIDIUM. It occurs in both animals and humans. Symptoms include severe DIARRHEA.

A toxin produced by certain pathogenic strains of ESCHERICHIA COLI such as ESCHERICHIA COLI O157. It is closely related to SHIGA TOXIN produced by SHIGELLA DYSENTERIAE.

Programs of surveillance designed to prevent the transmission of disease by any means from person to person or from animal to man.

Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy.

Serum dilution neutralization test for California group virus identification and serology. (1/166)

The serum dilution neutralization test was evaluated for serological diagnosis of California group arbovirus infections and identification of virus isolates. The technical advantages and the degree of subtype specificity of the serum dilution neutralization test over the hemagglutination inhibition test and the complement fixation test were demonstrated with paired specimens from human cases, single human survey sera, and sentinel rabbit sera. Twenty-one virus isolates from various geographical areas of the United States were also used to evaluate the efficacy of the serum dilution neutralization test for specific virus identification.

Mechanisms of arthropod transmission of plant and animal viruses. (2/166)

A majority of the plant-infecting viruses and many of the animal-infecting viruses are dependent upon arthropod vectors for transmission between hosts and/or as alternative hosts. The viruses have evolved specific associations with their vectors, and we are beginning to understand the underlying mechanisms that regulate the virus transmission process. A majority of plant viruses are carried on the cuticle lining of a vector's mouthparts or foregut. This initially appeared to be simple mechanical contamination, but it is now known to be a biologically complex interaction between specific virus proteins and as yet unidentified vector cuticle-associated compounds. Numerous other plant viruses and the majority of animal viruses are carried within the body of the vector. These viruses have evolved specific mechanisms to enable them to be transported through multiple tissues and to evade vector defenses. In response, vector species have evolved so that not all individuals within a species are susceptible to virus infection or can serve as a competent vector. Not only are the virus components of the transmission process being identified, but also the genetic and physiological components of the vectors which determine their ability to be used successfully by the virus are being elucidated. The mechanisms of arthropod-virus associations are many and complex, but common themes are beginning to emerge which may allow the development of novel strategies to ultimately control epidemics caused by arthropod-borne viruses.

El Nino and arboviral disease prediction. (3/166)

Recent El Nino events have stimulated interest in the development of modeling techniques to forecast extremes of climate and related health events. Previous studies have documented associations between specific climate variables (particularly temperature and rainfall) and outbreaks of arboviral disease. In some countries, such diseases are sensitive to El Nino. Here we describe a climate-based model for the prediction of Ross River virus epidemics in Australia. From a literature search and data on case notifications, we determined in which years there were epidemics of Ross River virus in southern Australia between 1928 and 1998. Predictor variables were monthly Southern Oscillation index values for the year of an epidemic or lagged by 1 year. We found that in southeastern states, epidemic years were well predicted by monthly Southern Oscillation index values in January and September in the previous year. The model forecasts that there is a high probability of epidemic Ross River virus in the southern states of Australia in 1999. We conclude that epidemics of arboviral disease can, at least in principle, be predicted on the basis of climate relationships. (+info)

Langerhans cells migrate to local lymph nodes following cutaneous infection with an arbovirus. (4/166)

Whereas there has been recent interest in interactions between dendritic cells and pathogenic viruses, the role of dendritic cells in the initiation of protective immunity to such organisms has not been elucidated. The aim of this study was to examine whether a resident dendritic cell population in the skin, Langerhans cells, respond to cutaneous viral infections which are effectively cleared by the immune system. We therefore characterized the ability of Langerhans cells to migrate to local draining lymph nodes following infection with the arthropod-borne viruses, West Nile virus or Semliki Forest virus. The data show that major histocompatibility complex class II+/NLDC145+/E-cadherin+ Langerhans cell numbers are increased in the draining lymph nodes of infected mice and this increase is accompanied by a concomitant decrease in the Langerhans cell density in the epidermis. Langerhans cell migration is associated with an accumulation of leukocytes in the lymph node, which is one of the earliest events in the initiation of an immune response. Both the migratory response and the draining lymph node leukocyte accumulation were abrogated if ultraviolet-inactivated instead of live viruses were used, suggesting the activation and subsequent migration of Langerhans cells requires a live, replicating antigen. Our findings are likely to have wider implications for the development of epidermally delivered vaccines and suggest that mobilization of dendritic cells may be involved in the development of immune responses to arthropod-borne viruses.

H-2-linked control of cytotoxic T-cell responsiveness to alphavirus infection. Presence of H-2Dk during differentiation and stimulation converts stem cells of low responder genotype to T cells of responder phenotype. (5/166)

Secondary Tc cells generated against Sindbis virus (SIN) are restricted to Dk. All other H-2K or D regions tested show low specific responsiveness. F1 hybrids between low and high responders show dominance of responsiveness but lack complementation. When BALB/c (KdIdDd) low responder fetal liver stem cells were allowed to mature in irradiated high responder recipients C3H.OH (KdIdDk) a response to Dk plus SIN could be generated with Tc cells of BALB/c origin. This result, together with the failure of complementation in the F1 hybrids, implies that the lesion of low responsiveness is in the inability of viral antigen to stimulate a Tc-cell response in association with any self H-2K or H-2D molecule (of those tested) other than H-2Dk. Hypotheses compatible with these data are discussed. (+info)

Standardization of immunoglobulin M capture enzyme-linked immunosorbent assays for routine diagnosis of arboviral infections. (6/166)

Immunoglobulin M antibody-capture enzyme-linked immunosorbent assay (MAC-ELISA) is a rapid and versatile diagnostic method that readily permits the combination of multiple assays. Test consolidation is especially important for arthropod-borne viruses (arboviruses) which belong to at least three virus families: the Togaviridae, Flaviviridae, and Bunyaviridae. Using prototype viruses from each of these families and a panel of well-characterized human sera, we have evaluated and standardized a combined MAC-ELISA capable of identifying virus infections caused by members of each virus family. Furthermore, by grouping antigens geographically and utilizing known serological cross-reactivities, we have reduced the number of antigens necessary for testing, while maintaining adequate detection sensitivity. We have determined that a 1:400 serum dilution is most appropriate for screening antiviral antibody, using a positive-to-negative ratio of >/=2.0 as a positive cutoff value. With a blind-coded human serum panel, this combined MAC-ELISA was shown to have test sensitivity and specificity that correlated well with those of other serological techniques. (+info)

Detection of anti-arboviral immunoglobulin G by using a monoclonal antibody-based capture enzyme-linked immunosorbent assay. (7/166)

Monoclonal antibody (MAb)-based capture enzyme-linked immunosorbent assays (ELISAs) for the detection of anti-arboviral immunoglobulin G (IgG ELISAs) were developed for a comprehensive array of medically important arboviruses from the Alphavirus, Flavivirus, and Bunyavirus genera. Tests were optimized and standardized so that maximum homology could be maintained among working parameters for the different viral agents, enabling a wide range of viruses to be easily tested for at one time. MAbs were screened for suitability as capture vehicles for antigens from the three genera. The final test configuration utilized group-reactive MAbs eastern equine encephalitis virus 1A4B-6, dengue 2 virus 4G2, and La Crosse encephalitis virus 10G5.4 to capture the specific inactivated viral antigens. Serum IgG was detected by using alkaline phosphatase-conjugated anti-human IgG (Fc portion). A dilution of 1:400 was chosen as the universal screening serum dilution, with endpoint titrations of serum samples testing positive eliminating occasional false-positive results. IgG ELISA results correlated with those of the standard plaque-reduction neutralization assays. As expected, some test cross-reactivity was encountered within the individual genera, and tests were interpreted within the context of these reactions. The tests were standardized for laboratory diagnosis of arboviral infections, with the intent that they be used in tandem with the corresponding IgM antibody-capture ELISAs. (+info)

Molecular strategies for interrupting arthropod-borne virus transmission by mosquitoes. (8/166)

Arthropod-borne virus (arbovirus) infections cause a number of emerging and resurgent human and veterinary infectious diseases. Traditional means of controlling arbovirus diseases include vaccination of susceptible vertebrates and mosquito control, but in many cases these have been unavailable or ineffective, and so novel strategies for disease control are needed. One possibility is genetic manipulation of mosquito vectors to render them unable to transmit arboviruses. This review describes recent work to test the concept of pathogen-derived resistance in arthropods by expression of viral genes in mosquito cell cultures and mosquitoes. Sense and antisense genome sequences from La Crosse virus (LAC) (a member of the Bunyaviridae) and dengue viruses serotypes 1 to 4 (DEN-1 to DEN-4) (members of the Flaviviridae) were expressed in mosquito cells from double-subgenomic and replicon vectors based on Sindbis virus (a member of the Togaviridae). The cells were then challenged with homologous or related viruses. For LAC, expression of antisense sequences from the small (S) genome segment, particularly full-length antisense S RNA, effectively interfered with replication of challenge virus, whereas expression of either antisense or sense RNA from the medium (M) segment was completely ineffective in LAC inhibition. Expression of sense and antisense RNA derived from certain regions of the DEN genome also blocked homologous virus replication more effectively than did RNA from other regions. Other parameters of RNA-mediated interference have been defined, such as the time when replication is blocked and the minimum size of effector RNA. The mechanism of RNA inhibition has not been determined, although it resembles double-stranded RNA interference in other nonvertebrate systems. Prospects for application of molecular strategies to control arbovirus diseases are briefly reviewed. (+info)

In recent decades, pathogenic flaviviruses (yellow fever virus, dengue [DENV], and Zika [ZIKV]) and the alphavirus chikungunya (CHIKV) have become the most common agents of emerging arbovirus diseases among humans. (cdc.gov)
Although some factors are unlikely to occur in non-arbovirus-endemic settings, such as Europe, emergence of these infectious diseases in these regions may result from viremic persons with imported infections and presence of competent Aedes albopictus mosquitoes ( 2 ). (cdc.gov)
Travelers are at high risk for infection by vectorborne diseases and may contribute to the spread of imported diseases in non-disease-endemic areas ( 4 ). (cdc.gov)
Arboviruses pose a significant threat to public health worldwide causing epidemics such as Dengue, West Nile, Zika & chikungunya diseases with considerable repercussions for the infected hosts. (researchsquare.com)
Undoubtedly, tropical, rural and agricultural areas are plagued by arboviruses, while climate change, urbanization and globalization affect the geographic and seasonal patterns of vector-borne diseases, facilitating efficient reproduction of insects and the pathogens they may carry. (researchsquare.com)
The arboviruses are the main causative agents of infectious diseases of public health importance [ 6 ]. (biomedcentral.com)
This manual has been prepared to provide guidelines for Human Services and local government staff, general practitioners and infection control officers involved in preventing and controlling infectious diseases. (1library.net)
Health authorities depend on medical practitioners for information on the incidence of infectious diseases and notification is vital in efforts to prevent or control the spread of infection. (1library.net)
These 'tails' of acute infectious diseases, herein referred to as PAISs, are characterized by an unexplained failure to recover from the acute infection, although studies of objective markers have so far been mostly unrevealing, and the pathogen rarely remains detectable by commonly used methods. (nature.com)
The nonpolio viruses (group A and B coxsackieviruses, echoviruses, enteroviruses) are responsible for a wide spectrum of diseases in persons of all ages, although infection and illness occur most commonly in infants. (medscape.com)
Arboviral diseases caused by dengue (DENV), Zika (ZIKV) and chikungunya (CHIKV) viruses represent a major public health problem worldwide, especially in tropical areas where millions of infections occur every year. (utb.edu.co)
Mosquito-borne diseases are a growing concern in Australia, and an understanding of the spatial distribution of infection is required to refine surveillance strategies and public health interventions. (who.int)
Because of the existence of vectors, imported mosquito-borne diseases may cause local infections and even outbreaks in areas with no previous record of a specific mosquito-borne pathogen detection. (biomedcentral.com)
Zoonotic infections - i.e. infectious diseases that can be mutually transmitted between humans and animals - are a constant challenge for society. (zoonosen.net)

Disease characteristics, clinical manifestations, and epidemiology generally mimic those of enteroviral infections. (medscape.com)
These animals are exposed to the same arboviral vectors (i.e., mosquitoes) as are the urban human population, which underscores the need to better understand the epidemiology of arboviruses in wildlife. (stlzoo.org)
1) describe the epidemiology, clinical manifestation, management and prevention of Zika virus disease, 2) discuss diagnostic testing for Zika virus infection and interpretation of test results, 3) articulate the importance of early recognition and reporting of cases, 4) state the recommendations for pregnant women and possible Zika virus exposure, and 5) discuss evaluation of infants with microcephaly and relationship of Zika in microcephaly. (cdc.gov)

Each jurisdiction is encouraged to review its current surveillance systems in light of the local threat of WNV and emerging arboviruses (e.g., dengue and chikungunya) and ensure it is able to rapidly detect and respond to critical changes in arbovirus activity. (cdc.gov)
Imported arbovirus infections (mostly dengue) were frequently diagnosed, although increased chikungunya and Zika virus infections coincided with their introduction and spread in the Americas. (cdc.gov)
Chikungunya infection is confirmed via serological tests, which take about 5 to 7 days into the illness to turn positive. (medscape.com)

Fewer than 20 of the 86 known pathogenic arboviruses can be considered major causes of human disease, and 3 of these, West Nile, chikungunya, and Zika viruses, have emerged from relative obscurity within only the past 20 years. (cdc.gov)
Most reports describe a self-limiting febrile illness that could easily be mistaken for another arboviral infection, such as dengue or chikungunya fever. (cdc.gov)
Zika virus, yellow fever, dengue, West Nile virus and chikungunya are all types of arboviruses that affect both animals and humans. (stlzoo.org)
To perform a molecular screening to detect infections by the mayaro virus and possible coinfections with Chikungunya during an outbreak in the state of Tocantins/Brazil in 2017. (biomedcentral.com)
The chikungunya (CHIKV) and mayaro (MAYV) viruses are endemic arboviruses in Brazil, belongs to the family Togaviridae (genus Alphavirus) . (biomedcentral.com)
We report the first case of autochthonous acute chikungunya infection in Saudi Arabia. (who.int)
The patient had PCR negative for chikungunya, while serology demonstrated significant titres of anti- chikungunya (anti-CHICKV) IgM (31.3 NTU) as well as IgG (27.6 NTU) and this confirmed the diagnosis of chikungunya infection. (who.int)
1-4 DENV used to be the only arbovirus isolated until October 2013 when FP experienced the largest outbreak of Zika virus (ZIKV) ever reported, 5,6 followed by an outbreak of chikungunya virus (CHIKV) that started in October 2014. (ijidonline.com)

Finally, this study discusses the complexity of the virome of Aedes and Culex mosquitoes and its implication for arbovirus transmission. (elsevier.com)
The Centers for Disease Control and Prevention (CDC) recommends that health care providers test all ill returned travelers for CHIK and dengue to improve clinical outcomes, since both share endemic areas and the same Aedes vector mosquito, co-infection occurs, and no good differential diagnostic signs or symptoms exist. (goodmedicine.org)

Aedes aegypti mosquitoes are a persistent human foe, transmitting arboviruses including dengue when they feed on human blood. (usda.gov)

Our work mainly focuses on the interactions between arboviruses and mosquitoes. (k-state.edu)
The overall question driving our research is determining why certain mosquitoes are able to serve as vectors of arboviruses, even though most mosquitoes are not. (k-state.edu)
2015. Tissue barriers to arbovirus infection in mosquitoes . (k-state.edu)
While studying mosquito-borne viral infections (arboviruses) in Kenya, LaBeaud and collaborators realized that the mosquitoes were coming from the plastic trash . (stanford.edu)
Because exposure to mosquitoes or ticks is the risk factor for transmission, the number of infections is highest in summer and early fall, in concordance with high mosquito populations. (medscape.com)
In addition, at least in mosquitoes, another RNAi mechanism mediated by PIWI interacting RNAs (piRNAs) is activated by viral infection. (plos.org)
Animals become infected with arboviruses when mosquitoes carrying any of these viruses bite them, transmitting it from mosquito to animal. (stlzoo.org)
