Human enteroviruses and human parechoviruses are associated with a broad range of diseases and even severe and fatal conditions. For human cosaviruses, the etiological role is yet unknown. Little is known about the circulation of non-polio enteroviruses, human parechoviruses, and human cosaviruses in Nigeria. A total of 113 stool samples were collected from healthy individuals in Osun State between February 2016 and May 2017. RT-PCR assays targeting the 5′ non-coding region (5′ -NCR) were used to screen for human enteroviruses, human parechoviruses, and human cosaviruses. For human enteroviruses, species-specific RT-PCR assays targeting the VP1 regions were used for molecular typing. Inoculation was carried out on RD-A, CaCo-2, HEp-2C, and L20B cell lines to compare molecular and virological assays. Ten samples tested positive for enterovirus RNA with 11 strains detected, including CV-A13 (n = 3), E-18 (n = 2), CV-A20 (n = 1), CV-A24 (n = 1), EV-C99 (n = 1), and EV-C116 (n = 2). Three ...
TY - JOUR. T1 - Enteroviruses. AU - Muir, Peter. N1 - Copyright: Copyright 2010 Elsevier B.V., All rights reserved.. PY - 2009/12. Y1 - 2009/12. N2 - The human enteroviruses are ubiquitous small non-enveloped RNA viruses that are important causes of aseptic meningitis, myocarditis, hand, foot and mouth disease, acute haemorrhagic conjunctivitis, herpangina, and Bornholm disease (pleurodynia), as well as non-specific febrile and respiratory illnesses, and rash. They include the coxsackieviruses, echoviruses and polioviruses. The polioviruses cause paralytic poliomyelitis, which has almost been eliminated through the use of live and inactivated poliovirus vaccine. Neonatal enterovirus infection can be particularly severe. Laboratory diagnosis of enterovirus infections has been greatly improved in recent years by replacing viral culture and serology with enterovirus-specific polymerase chain reaction; this is now part of routine cerebrospinal fluid investigations. Although specific antiviral ...

The efficacy of germicidal ultraviolet (UV-C) light emitting diodes (LEDs) was evaluated for inactivating human enteroviruses included on the United States Environmental Protection Agency (EPA)s Contaminant Candidate List (CCL). A UV-C LED device, emitting at peaks of 260 nm and 280 nm and the combination of 260/280 nm together, was used to measure and compare potential synergistic effects of dual wavelengths for disinfecting viral organisms. The 260 nm LED proved to be the most effective at inactivating the CCL enteroviruses tested. To obtain 2-log10 inactivation credit for the 260 nm LED, the fluences (UV doses) required are approximately 8 mJ/cm2 for coxsackievirus A10 and poliovirus 1, 10 mJ/cm2 for enterovirus 70, and 13 mJ/cm2 for echovirus 30. No synergistic effect was detected when evaluating the log inactivation of enteroviruses irradiated by the dual-wavelength UV-C LEDs.. ...
Coxsackievirus is a virus that belongs to a family of nonenveloped, linear, positive-sense single-stranded RNA viruses, Picornaviridae and the genus Enterovirus, which also includes poliovirus and echovirus. Enteroviruses are among the most common and important human pathogens, and ordinarily its members are transmitted by the fecal-oral route. Coxsackieviruses share many characteristics with poliovirus. With control of poliovirus infections in much of the world, more attention has been focused on understanding the nonpolio enteroviruses such as coxsackievirus. Coxsackieviruses are among the leading causes of aseptic meningitis (the other usual suspects being echovirus and mumps virus). The entry of coxsackievirus into cells, especially endothelial cells, is mediated by Coxsackie virus and adenovirus receptor. Coxsackieviruses are divided into group A and group B viruses based on early observations of their pathogenicity in neonatal mice. Group A coxsackieviruses were noted to cause a flaccid ...
Using Chinas national surveillance data on hand, foot and mouth disease (HFMD) for 2008-2015, we described the epidemiologic and virologic features of recurrent HFMD. A total of 398,010 patients had HFMD recurrence; 1,767 patients had 1,814 cases of recurrent laboratory-confirmed HFMD: 99 reinfections of enterovirus A71 (EV-A71) with EV-A71, 45 of coxsackievirus A16 (CV-A16) with CV-A16, 364 of other enteroviruses with other enteroviruses, 383 of EV-A71 with CV-A16 and CV-A16 with EV-A71, and 923 of EV-A71 or CV-A16 with other enteroviruses and other enteroviruses with EV-A71 or CV-A16. The probability of HFMD recurrence was 1.9% at 12 months, 3.3% at 24 months, 3.9% at 36 months, and 4.0% at 38.8 months after the primary episode. HFMD severity was not associated with recurrent episodes or time interval between episodes. Elucidation of the mechanism underlying HFMD recurrence with the same enterovirus serotype and confirmation that HFMD recurrence is not associated with disease severity is needed.
BACKGROUND: Enteroviruses are non-enveloped, frequently pathogenic RNA viruses infecting humans. Infection is potentially transmissible through blood or blood component transfusion from donor in the viremic phase before seroconversion for antibody. To investigate the threat to blood safety from enteroviruses, a large-scale survey of frequency and levels of viremia in blood donors was conducted. STUDY DESIGNS AND METHODS: Blood donations from Scotland over a period of 22 calendar months were screened for enterovirus RNA sequences by PCR. Positive samples were quantified, and serotypes were identified by nucleotide sequencing of VP1. RESULTS: From a total of 3658 pools of 95 donations tested, 73 samples that were enterovirus-positive were identified (corrected annual frequency 0.024% or 1 in 4000). The highest rates of viremia were in late summer months (e.g., 0.055%, 1 in 1800 in July) and lowest from January to May (0.009 and 0.012%). Viral loads ranged from 500 (the lower cutoff of the assay) to
Enteroviruses (EVs) are viruses of the family Picornaviridae that cause mild to severe infections in humans and in several animal species, including non-human primates (NHPs). We conducted a survey and characterization of enteroviruses circulating between humans and great apes in the Congo. Fecal samples (N = 24) of gorillas and chimpanzees living close to or distant from humans in three Congolese parks were collected, as well as from healthy humans (N = 38) living around and within these parks. Enteroviruses were detected in 29.4% of gorilla and 13.15% of human feces, including wild and human-habituated gorillas, local humans and eco-guards. Two identical strains were isolated from two humans coming from two remote regions. Their genomes were similar and all genes showed their close similarity to coxsackieviruses, except for the 3C, 3D and 5-UTR regions, where they were most similar to poliovirus 1 and 2, suggesting recombination. Recombination events were found between these strains, poliovirus 1 and

Virus isolation in cell cultures has been the standard method for enterovirus 71 identification in Clinical Virology Laboratories. However, virus isolation takes 5-10 days when using cell culture. A microchip for enterovirus 71 detection was developed as an alternative diagnostic method. The novel approach is based on hybridization of amplified DNA specimens with oligonucleotide DNA probes immobilized on a microchip. Two oligonucletides were used as detection ...
This review provides the latest update on the interplay between human host factors/processes and non-polio enteroviruses (NPEV). We focus on the interactions involved in viral attachment, entry, internalization, uncoating, replication, virion assembly and eventual egress of the NPEV from the infected cells. We emphasize on the virus- human host interplay and highlight existing knowledge gaps that needs further studies. Understanding the NPEV-human host factors interactions will be key in the design and development of vaccines as well as antivirals against enteroviral infections. Dissecting the role of human host factors during NPEV infection cycle will provide a clear picture of how NPEVs usurp the human cellular processes to establish an efficient infection. This will be a boost to the drug and vaccine development against enteroviruses which will be key in control and eventual elimination of the viral infections.. Conclusions: The emergence of outbreaks of enteroviral infections in different ...
Enteroviruses (EVs) species A are a major public health issue in the Asia-Pacific region and cause frequent epidemics of hand, foot and mouth disease (HFMD) in China. Mild infections are common in children; however, HFMD can also cause severe illness that affects the central nervous system. To molecularly characterize EVs, a prospective HFMD virological surveillance program was performed in China between 2013 and 2016. Throat swabs, rectal swabs and stool samples were collected from suspected HFMD patients at participating hospitals. EVs were detected using generic real-time and nested reverse transcription-polymerase chain reactions (RT-PCRs). Then, the complete VP1 regions of enterovirus A71 (EV-A71), coxsackievirus A16 (CVA16) and CVA6 were sequenced to analyze amino acid changes and construct a viral molecular phylogeny. Of the 2836 enrolled HFMD patients, 2,517 (89%) were EV positive. The most frequently detected EVs were CVA16 (32.5%, 819), CVA6 (31.2%, 785), and EV-A71 (20.4%, 514). The
Picornaviruses represent a very large virus family with respect to the number of members but one of the smallest in terms of virion size and genetic complexity. They include two major groups of human pathogens: enteroviruses and rhinoviruses. Enteroviruses are transient inhabitants of the human alimentary tract and may be isolated from the throat or lower intestine. Rhinoviruses are associated with the respiratory tract and isolated chiefly from the nose and throat. Less -common picornaviruses associated with human illness include hepatitis A virus, parechovirus, cardiovirus, and Aichi virus. Several genera of picornaviruses are also associated with -animal, plant, and insect disease. ...

We have performed immunostructural analyses of three closely related picornaviruses in order to gain understanding of the biochemical and structural basis of serotype specificity. We carried out sequence alignments of the capsid regions of three bovine enterovirus strains: VG-5-27 and M-4 from serotype 1 and PS-87 from serotype 2. Using our knowledge of the three dimensional and antigenic structure of strain VG-5-27 and the high levels of sequence identity between the strains, we have calculated the structures and solvent-accessible electrostatic potentials of the epitopes of all three viruses. We have demonstrated the viability of the molecular models of the epitopes of the M-4 and PS-87 strains. In each of the strains, we have explained the serotype specificities in terms of specific physical and chemical properties, and identified individual residues which are pivotal in determination of antibody recognition. These changes are in agreement with the known cross-reactivity of peptide and ...

One leading candidate is enterovirus D68, which has caused outbreaks of respiratory disease in North America, but surveillance data on this virus is sparse.. Here, Park et al. modeled the epidemiology of enterovirus D68 in the U.S. with data from the BioFire Syndromic Trends repository and compared nationwide enterovirus D68 prevalence to the actual incidence of reported AFM cases. Using a powerful algorithm, the team observed a strong correlation between enterovirus D68 and AFM: they predicted that enterovirus D68 peaked roughly every two years, with the peaks occurring directly before AFM epidemics in the autumn.. The researchers also predicted that moderate or large outbreaks of enterovirus D68 would have occurred under normal conditions in 2020, but that mask-wearing and other measures reduced the risk of outbreaks and likely contributed to the observed decline in cases of AFM..

Objective: The study aims to understand the characteristics and epidemic trend of the pathogen of hand, foot and mouth disease (HFMD) in Guangxi regions, China. Besides, it aims to analyze the differences of intestinal virus detection rate between anal swab and pharyngeal swab samples. Methods: Anal swab and pharyngeal swabs of suspected HFMD children were collected in our hospital from 2012 to 2015. Real-time fluorescent PCR (Polymerase Chain Reaction) was used to detect enterovirus 71 (EV71), coxsackie virus type 16 (CA16), and universal intestinal virus nucleic acid (EV). Composition and conversion of predominant pathogens were analyzed, and paired samples test results of swabs anal and pharyngeal swab were statistically analyzed. Results: There are 681 cases with enterovirus in 2351 cases of patients. Among those who got enterovirus, there are 501 cases of EV71, 102 cases of CA16 and 79 cases of EV. From 2012 to 2015, the total proportion of the virus detection is 46.47%, 16.23%, 41.02% and 15.33%

Receptor binding and subsequent cell-mediated internalization or disassembly are the initial steps in virus replication. Cell surface molecules that participate in this process are the primary determinants of virus tissue tropism. Monoclonal antibody blockade, immunoprecipitation, and DNA transfection were used to identify decay accelerating factor as a major cell attachment receptor for coxsackieviruses B1, B3, and B5. However, expression of human decay acceleration factor on the surface of nonpermissive murine fibroblasts led only to virus attachment without subsequent replication, and it was concluded that an additional cellular cofactor(s) is required to facilitate cell entry and subsequent replication.
The Enterovirus genus within the family Picornaviridae contains over 100 serotypes, of which sixty-four are known to be human pathogens. Infection with this group of RNA viruses produces a myriad of clinical conditions including poliomyelitis, meningitis, encephalitis, respiratory illnesses, and hand-foot-and-mouth disease. Outbreaks have been documented worldwide; significant morbidity and mortality exist to warrant laboratory surveillance. Traditionally, enteroviruses have been identified to the level of serotype by the serum neutralization assay. However, numerous problems are associated with this assay. The serum neutralization assay is labor intensive, results are often ambiguous, and reagents are becoming difficult to obtain. Recently, molecular-based typing protocols have been described that are cost effective and produce results that are more reliable. The overall objective of this thesis was to implement a molecular-based typing protocol to replace the serum neutralization method currently used
BACKGROUND: Enterovirus (EV) meningitis is common in infants and may have neurologic complications. Treatment of older children and adults with pleconaril has been associated with reduced severity and duration of symptoms. This study evaluated the pharmacokinetics, safety and efficacy of pleconaril in infants with EV meningitis. METHODS: Infants < or =12 months old with suspected EV meningitis were randomized 2:1 to receive pleconaril, 5 mg/kg/dose orally three times a day or placebo for 7 days. Evaluations included pharmacokinetic determinations, safety laboratory testing, serial culture and PCR assays and clinical evaluations. RESULTS: Of 21 evaluable subjects 20 were confirmed with EV infection (12 pleconaril, 8 placebo). Among pleconaril-treated subjects 26 of 29 peak and trough pleconaril levels exceeded the 90% inhibitory concentration for EVs. A median 3.5-fold drug accumulation occurred between Days 2 and 7. Pleconaril was well-tolerated, although twice as many adverse events occurred ...

Enterovirus 71 (EV71) is a common cause of Hand, foot, and mouth disease (HFMD) and may also cause severe neurological diseases, such as encephalitis and poliomyelitis-like paralysis. To examine the genetic diversity of EV71, we determined and analyzed the complete VP1 sequences (891 nucleotides) from nine EV71 strains isolated in Fuyang, China. We found that nine EV71 strains isolated were over 98% homologous at the nucleotide level and 93%-100% homologous to members of the C4 subgenogroup. At the amino acid level, these Fuyang strains were 99% -100% homologous to one another, 97%-100% homologous to members of the C4 subgenogroup, and the histidine(H) at amino acid position 22 was conserved among the Fuyang strains. The results indicate that Fuyang isolates belong to genotype C4, and an H at position 22 appears to be a marker for the Fuyang strains.

AB - BackgroundOral poliovirus vaccine (OPV) is less immunogenic in low- or middle-income than in high-income countries. We tested whether bacterial and viral components of the intestinal microbiota are associated with this phenomenon.MethodsWe assessed the prevalence of enteropathogens using TaqMan array cards 14 days before and at vaccination in 704 Indian infants (aged 6-11 months) receiving monovalent type 3 OPV (CTRI/2014/05/004588). Nonpolio enterovirus (NPEV) serotypes were identified by means of VP1 sequencing. In 120 infants, the prevaccination bacterial microbiota was characterized using 16S ribosomal RNA sequencing.ResultsWe detected 56 NPEV serotypes on the day of vaccination. Concurrent NPEVs were associated with a reduction in OPV seroconversion, consistent across species (odds ratio [95% confidence interval], 0.57 [.36-.90], 0.61 [.43-.86], and 0.69 [.41-1.16] for species A, B, and C, respectively).

Hand, foot, and mouth disease (HFMD) is a common infection caused by a group of viruses. It typically begins with a fever and feeling generally unwell. This is followed a day or two later by flat discolored spots or bumps that may blister, on the hands, feet, and mouth, and occasionally buttocks and groin. Signs and symptoms normally appear 3-6 days after exposure to the virus. The rash generally goes away on its own in about a week. Fingernail and toenail loss may occur a few weeks later, but will regrow with time. The viruses that cause HFMD are spread through close personal contact, through the air from coughing, and the feces of an infected person. Contaminated objects can also spread the disease. Coxsackievirus A16 is the most common cause and Enterovirus 71 is the second-most common cause. Other strains of coxsackievirus and enterovirus can also be responsible. Some people may carry and pass on the virus despite having no symptoms of disease. Other animals are not involved. Diagnosis can ...

The genetic plasticity of viruses with RNA genomes results from high mutation rates and genetic recombination, facilitating the emergence of new epidemic viral strains. We study genetic and biological aspects of these viruses from fundamental and public-health standpoints, focusing on enteroviruses.. Human enteroviruses belong to the Picornaviridae family, a large group of human and animal pathogens. They mostly cause asymptomatic intestinal infections, but they can also cause acute damage to the central nervous system leading to meningitis, encephalitis, or even flaccid paralysis, which is mostly due to infections with poliovirus (poliomyelitis) and enterovirus A71 (EV-A71).. In 1988, the WHO established a poliomyelitis eradication program based on massive vaccination campaigns with oral polio vaccine (OPV). This vaccine consists of live attenuated strains that multiply to high titers in the intestine. There is also an inactivated virus vaccine. Following this campaign, a marked decrease in the ...
Enteroviruses (EV) can cause severe neurological and respiratory infections, and occasionally lead to devastating outbreaks as previously demonstrated with EV-A71 and EV-D68 in Europe. However, these infections are still often underdiagnosed and EV typing data is not currently collected at European level. In order to improve EV diagnostics, collate data on severe EV infections and monitor the circulation of EV types, we have established European non-polio enterovirus network (ENPEN). First task of this cross-border network has been to ensure prompt and adequate diagnosis of these infections in Europe, and hence we present recommendations for non-polio EV detection and typing based on the consensus view of this multidisciplinary team including experts from over 20 European countries. We recommend that respiratory and stool samples in addition to cerebrospinal fluid (CSF) and blood samples are submitted for EV testing from patients with suspected neurological infections. This is vital since ...
Infecting the enterovirus can be from a sick person or from a carrier that is not sick, but is only a carrier of infection. Most often enterovirus children are ill. It is transmitted by the fecal-oral and food way, therefore, it is said that a person was poisoned while eating food. Often infection is due to infected vegetables and fruits that have been badly washed. Enterovirus gets to the fruit during irrigation with sewage, and then we are on the table.

Hand, foot, and mouth disease (HFMD) is a common viral illness in infants and children caused by viruses that belong to the enterovirus genus of the picornavirus family. Although most HFMD cases do not result in serious complications, outbreaks of HFMD caused by enterovirus 71 (EV71) can present with a high rate of neurological complications, including meningoencephalitis, pulmonary complications, and can even cause infant death. HFMD caused by EV71 has become a major emerging infectious disease in Asia and the highly pathogenic potential of EV71 clearly requires the attention of world medical community.. The phase I study of inactivated vaccine (vero cell) against EV71 has completed last month in Jiangsu Province in China. The data from the phase I study suggested that the inactivated EV71 vaccine had a clinically acceptable safety and good immunogenicity for healthy Chinese children and infants. In order to provide more evidence for the immunogenicity of the vaccine, to further explore the ...
Fourteen children across California have been sickened by enterovirus D68 so far this year, but a separate investigation has revealed that the rare respiratory illness was present in 2012 in patients who suffered some paralysis, state health officials said Friday.. The California Department of Public Health identified 35 patients with paralysis and spinal cord illnesses since 2012. Of those patients, three had the virus known as EV-D68. There were two in 2012 and one this year. The finding raises the question but doesnt answer conclusively if there is a link between the rare respiratory illness and limb paralysis. Because EV-D68 was found in respiratory specimens from these patients, it is not known whether EV-D68 was a cause of paralysis or a coincidental finding, said Dr. Gil Chavez, state epidemiologist for the Center for Infectious Diseases at the state health department. The CDC is investigating reports of paralysis and neurological issues in several children in Colorado. Health experts ...
Enterovirus D68 (EV-D68) is a human respiratory virus associated with acute flaccid myelitis, a rare paralytic disease primarily occurring in young children. To develop a potential therapeutic agent for this emerging disease, Vogt et al. screened B cells from participants with past EV-D68 infection for virus-binding antibodies and isolated a series of human monoclonal antibodies (mAbs). One mAb that neutralized virus from all EV-D68 clades tested was shown by cryo-electron microscopy to bind a conformational epitope on the viral capsid surface. This highly cross-reactive mAb also protected immunodeficient mice from EV-D68-induced respiratory and neurological disease when given as prophylaxis or therapy. This research sets the stage for clinical testing of antibody therapy in patients with severe EV-D68 disease when the next virus outbreak occurs. ...

Opsoclonus-myoclonus syndrome is a well recognised disease in children. The aetiology, except for neuroblastoma accounting for a few patients, remains unknown.1 Viral infection is one of the presumed physiopathological mechanisms. We report a case of opsoclonus-myoclonus syndrome due to enterovirus infection with spontaneous remission, no recurrence, and full recovery after 36 months follow up.. A two year old girl, with a previously normal development, exhibited acute ataxia after a two day history of fever and vomiting. One day later, she developed myoclonic jerks and opsoclonus. Initially, she was febrile (39°C), irritable, and unable to sit or to stand because of truncal ataxia. There was resistance to neck flexion. Rapid irregular and oscillatory eye movements were seen with continual myoclonus of the neck and limbs. Enterovirus RNA was detected in CSF at day 3 by polymerase chain reaction (PCR).2 The CSF, on day 3, contained 113 leucocytes/mm3 (98% lymphocytes and 2% polymorphonuclear ...
Human enterovirus C99 (EV-C99) belongs to Human enterovirus C. EV-C99 is a positive-sense, single-stranded RNA virus. The genome is approximately 7.4 kb, including a 5ʹ untranslated region (UTR), structural polypeptide P1, nonstructural polypeptides P2 and P3, and a 3ʹ UTR. All EV-C99 strains can be classified into three genotypes, A, B, and C (1). EV-C99 strains have been isolated from acute flaccid paralysis (AFP) patients and from oral polio-vaccinated and healthy individuals (1-4). At present, there are very few EV-C99 sequences available in the GenBank database.. A stool sample of a healthy child in Yunnan, China, was inoculated into human embryonic lung diploid fibroblasts (KMB17) and propagated in up to three passages. The sample induced a cytopathic effect (CPE), was stored at −80°C, and was named strain K292/YN/CHN/2013. The viral RNA was extracted from cell culture supernatants using the AxyPrep body fluid viral DNA/RNA miniprep kit (Axygen, Union City, CA). Then, the partial VP1 ...

THURSDAY, Oct. 15, 2015 (HealthDay News) -- Enterovirus D68 made headlines in 2014 when it sickened scores of kids across North America, but a new study says the aggressive virus proved no more deadly than other common cold germs.. The virus was more aggressive, spreading quickly and causing understandable alarm, said Dr. Dominik Mertz, lead author of the study and an assistant professor of infectious diseases at McMaster University in Ontario, Canada.. Children who came down with enterovirus D68 (EV-D68) also were more likely to have serious difficulty breathing, compared to kids who caught other viruses, Mertz and his colleagues found.. But children with EV-D68 didnt have a greater risk of death than kids with other viral infections, the researchers found. Youngsters with the virus were also not significantly more likely to need admission to an intensive care unit (ICU), the study authors reported.. They came in sicker, but the disease didnt progress to a critical level more frequently than ...
What is the treatment for this virus? There is no medicine to treat Enterovirus D68. The care for it is what we call supportive, meaning we do things to help with symptoms. We give oxygen if needed, fluids for dehydration (fluid loss), and medicines such as acetaminophen to treat fever and other symptoms. Theres no vaccine, either. Prevention, and being aware of symptoms and getting medical attention, are key..

There are many types of enteroviruses. The viruses mostly cause illness in babies, children, and teens. This is because most adults have already had enteroviruses and have built up immunity.
To analyze the epidemiological characteristics and pathogenic molecular characteristics of an hand, foot, and mouth disease (HFMD) outbreak caused by enterovirus 71 in Linyi City, Shandong Province, China during November 30 to December 28, 2010. One hundred and seventy three stool specimens and 40 throat samples were collected from 173 hospitalized cases. Epidemiologic and clinical investigations, laboratory testing, and genetic analyses were performed to identify the causal pathogen of the outbreak. Among the 173 cases reported in December 2010, the male-female ratio was 1.88: 1; 23 cases (13.3%) were severe. The majority of patients were children aged | 5 years (95.4%). Some patients developed respiratory symptoms including runny nose (38.2%), cough (20.2%), and sore throat (14.5%). One hundred and thirty eight EV71 positive cases were identified based on real time reverse-transcription PCR detection and 107 isolates were sequenced with the VP1 region.

During 2005, 764 children were brought to a large childrens hospital in Ho Chi Minh City, Vietnam, with a diagnosis of hand, foot, and mouth disease. All enrolled children had specimens (vesicle fluid, stool, throat swab) collected for enterovirus isolation by cell culture. An enterovirus was isolated from 411 (53.8%) of the specimens: 173 (42.1%) isolates were identified as human enterovirus 71 (HEV71) and 214 (52.1%) as coxsackievirus A16. Of the identified HEV71 infections, 51 (29.5%) were complicated by acute neurologic disease and 3 (1.7%) were fatal. HEV71 was isolated throughout the year, with a period of higher prevalence in October-November. Phylogenetic analysis of 23 HEV71 isolates showed that during the first half of 2005, viruses belonging to 3 subgenogroups, C1, C4, and a previously undescribed subgenogroup, C5, cocirculated in southern Vietnam. In the second half of the year, viruses belonging to subgenogroup C5 predominated during a period of higher HEV71 activity ...
Introduction. Enteroviruses are the most frequent cause of aseptic meningitis in the paediatric age group.1 Cases of meningitis caused by enterovirus are usually benign and only require symptomatic treatment. However, the difficulty of differentiating them from bacterial meningitis in the initial assessment may lead to the unnecessary use of antibiotics, hospital admission and increases in the length of stay.2-4 Currently, molecular diagnostic tests for the detection of enterovirus in cerebrospinal fluid (CSF) specimens, which have a high sensitivity and specificity and offer quick results, are displacing viral culture,5,6 which is slower and whose results depend on the viability of the viruses contained in the clinical specimen. Some of these molecular tests are fully automated, as is the case of the Xpert EV assay (Cepheid®), which uses the GeneXpert® Dx system.. The aim of our study was to analyse changes in clinical practice since the introduction of this diagnostic test for the detection ...
There is no vaccine to prevent coxsackievirus infection. Hand washing is the best protection. Remind everyone in your family to wash their hands frequently, particularly after using the toilet (especially those in public places), after changing a diaper, before meals, and before preparing food. Shared toys in childcare centers should be routinely cleaned with a disinfectant because the virus can live on these objects for days.. Kids who are sick with a coxsackievirus infection should be kept out of school or childcare for a few days to avoid spreading the infection.. The duration of an infection varies widely. For fever without other symptoms, a childs temperature may return to normal within 24 hours, although the average fever lasts 3 to 4 days. Hand, foot, and mouth disease usually lasts for 2 or 3 days; viral meningitis can take 3 to 7 days to clear up.. ...

Aims/hypothesis Virally induced inflammatory responses, beta cell destruction and release of beta cell autoantigens may lead to autoimmune reactions culminating in type 1 diabetes. Therefore, viral capability to induce beta cell death and the nature of virus-induced immune responses are among key determinants of diabetogenic viruses. We hypothesised that enterovirus infection induces a specific gene expression pattern that results in islet destruction and that such a host response pattern is not shared among all enterovirus infections but varies between virus strains. Methods The changes in global gene expression and secreted cytokine profiles induced by lytic or benign enterovirus infections were studied in primary human pancreatic islet using DNA microarrays and viral strains either isolated at the clinical onset of type 1 diabetes or capable of causing a diabetes-like condition in mice. Results The expression of pro-inflammatory cytokine genes (IL-1-a, IL-1-β and TNF-a) that also mediate ...
Background Human Parechovirus (HPeV) causes central nervous system (CNS) infection in infants. To further understand HPeV CNS infection, we describe its clinical, laboratory and epidemiologic characteristics from a Midwestern U.S. tertiary care center. Because HPeV CNS infections have appeared clinically and seasonally similar to enterovirus (EV) infections, we retrospectively compared characteristics of young infants undergoing sepsis evaluations in whom HPeV, EV or neither were detected in CSF. Methods HPeV real-time RT-PCR assay was performed on frozen nucleic acid extracts of CSF specimens submitted for EV RT-PCR assay from children seen at our hospital in 2009. HPeV genotyping was performed by sequencing of the viral protein 1 (VP1) region. Clinical data were abstracted from medical records retrospectively for EV-positive, HPeV-positive and age-matched controls in whom neither virus was detected from CSF testing. Results HPeV was detected in 66/388 (17%) CSF specimens while EV was detected ...

Over the past 8 years, human enteroviruses (HEVs) have caused 27 227 cases of hand, foot and mouth disease (HFMD) in Xiamen, including 99 severe cases and six deaths. We aimed to explore the molecular epidemiology of HFMD in Xiamen to inform the development of diagnostic assays, vaccines and other interventions. From January 2009 to September 2015, 5866 samples from sentinel hospitals were tested using nested reverse transcription PCR that targeted the HEV 5′ untranslated region and viral protein 1 region. Of these samples, 4290 were tested positive for HEV and the amplicons were sequenced and genotyped. Twenty-two genotypes were identified. Enterovirus 71 (EV71) and coxsackieviruses A16, A6 and A10 (CA16, CA6 and CA10) were the most common genotypes, and there were no changes in the predominant lineages of these genotypes. EV71 became the most predominant genotype every 2 years. From 2013, CA6 replaced CA16 as one of the two most common genotypes. The results demonstrate the vast diversity of ...
Researchers at Washington University School of Medicine in St. Louis have developed a diagnostic test to quickly detect enterovirus D68 (EV-D68), a respiratory virus that caused unusually severe illness in children last year. The outbreak caused infections at an unprecedented rate, with over 1,000 confirmed cases and 14 reported deaths nationwide, according to the Centers for
http://www.cnn.com/2014/09/16/health/enterovirus-outbreak/ (CNN) -- Since mid-August, the Centers for Disease Control and Prevention has confirmed more than 100 cases of Enterovirus D68 in 12 states: Alabama, Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Missouri, Montana, New York and Oklahoma. Yet the real number of severe respiratory illnesses caused by this virus is probably even higher, the…
Enterovirus symptoms are similar to the common cold, and include fever, coughing, sneezing, runny nose, and muscle aches. While most cases of illness are mild, some people can become seriously ill and have complications such as paralysis, meningitis or encephalitis. Children (newborns through teenagers) are most likely to be infected and become sick. Infants, children with asthma, or children with breathing difficulties have a greater chance of complications.. ...
Acute flaccid myelitis (AFM) are reported to be associated with enterovirus D68 infection. Though an increasing number of AFM cases were reported with EV-D68 infection in the US, few such cases have been found in China. A 6-year-old boy presented with acute flaccid myelitis (AFM) involving left arm after fever and respiratory symptoms for 6 days. Computed Tomography (CT) revealed inflammation in both lungs and magnetic resonance imaging (MRI) of the brain and spine showed swelling in the left frontal lobe and brain stem. The patient was diagnosed with meningomyelitis. EV-D68 was detected from pharyngeal samples 36 days after the onset of the disease. We report the first EV-D68 infection in case of AFM in mainland China. AFM surveillance systems is recommended to be established in China to guide diagnosis, case reporting, and specimen collection and testing for better understanding its etiologies.

Recent outbreaks Outbreaks of hand, foot, and mouth disease are regularly reported from Singapore, most recently in April 2006, April 2007, April 2008, April 2009, and April 2012 (see ProMED-mail, April 24, 2007, April 27, 2008, and May 7, 2012). More than 13,000 cases had been reported for the year as of the end of April, 2012. The outbreaks in 2006 and 2007 were caused by coxsackievirus A16, whereas most of the infections in 2008 were caused by enterovirus 71, which causes a more severe form of the disease. The cases in the 2012 outbreak have been mild and do not appear to be due to enterovirus 71. Hand, foot, and mouth disease is characterized by fever, oral blisters, and a rash or blisters on the palms and soles, usually occurring in young children. Most cases resolve uneventfully. Infections caused by enterovirus 71, unlike coxsackievirus A16, are sometimes complicated by encephalitis (inflammation of the brain), myocarditis (inflammation of the heart muscle), or pulmonary edema (fluid in ...
Coxsackievirus is a virus type that belongs to the genus. It causes coxsackievirus infection (CI) which is highly contagious and spreads from individual to individual through direct contact by contaminated hands, saliva, respiratory droplets and faeces.
How soon will someone become ill after getting infected?. The usual period from infection to onset of symptoms is three to six days. Fever is often the first symptom of HFMD.. Who is at risk for HFMD? HFMD occurs mainly in children under 10 years old, but adults may also be at risk. Everyone is susceptible to infection.. Infection results in immunity to the specific virus, but a second episode may occur following infection with a different member of the enterovirus group.. When and where does HFMD occur?. Individual cases and outbreaks of HFMD occur worldwide, more frequently in summer and early autumn.. How is HFMD diagnosed?. HFMD is one of many infections that result in mouth sores.. Another common cause is oral herpesvirus infection, which produces an inflammation of the mouth and gums (sometimes called stomatitis).. Usually, the doctor can distinguish between HFMD and other causes of mouth sores based on the age of the patient, the pattern of symptoms reported by the patient or parent, and ...
Most sufferers will have no symptoms at all. Those who feel symptoms usually feel mild flu like symptoms including fever, head and muscle aches and perhaps a rash. A mild sore throat is usual, and sometimes nausea or abdominal pain is present.. Some children develop a condition known as hand-foot-and-mouth disease, where small painful blisters appear in the mouth, on the tongue and inside of the cheeks, and on the palms and soles of the feet.. Others develop painful blisters and ulcers in the back of the throat known as herpangina. These can appear on the tonsils and soft palate - the soft fleshy part on the roof of the mouth.. Some suffer chest pain when breathing.. Other variations of the coxsackie virus include myositis, a muscle infection; meningitis, an infection of the membranes that cover the brain; and encephalitis, a brain infection. These can be dangerous, and fatal in some cases.. ...
Human coxsackievirus A6 (CVA6) is an enterically transmitted enterovirus. Until recently, CVA6 infections were considered as being of minor clinical significance, and only rarely aetiologically linked with hand, foot and mouth disease (HFMD) associated with other species A enteroviruses (particularly EV71 and CVA16). From 2008 onwards, however, CVA6 infections have been associated with several outbreaks worldwide of atypical HFMD (aHFMD) accompanied by a varicelliform rash. We recently reported CVA6-associated eczema herpeticum occurring predominantly in children and young adults in Edinburgh in January and February 2014. To investigate genetic determinants of novel clinical phenotypes of CVA6, we genetically characterized and analysed CVA6 variants associated with eczema herpeticum in Edinburgh in 2014 and those with aHFMD in CAV isolates collected from 2008. A total of eight recombinant forms (RFs) have circulated worldwide over the past 10 years, with the particularly recent appearance of RF-H
Full Text - Coxsackie B3 virus (CVB3) is a member of small RNA viruses that belongs to the genus Enterovirus of the family Picornaviridae and CVB3 is the main pathogen of acute and chronic viral myocarditis. In this study RT-qPCR was used to determine the expression of miR-107 in CVB3-infected and uninfected HeLa cells. The experimental results show that the level of miR-107 began to rise at 4 h after the infection, and significantly boosted at 6 h. Based on the results of this experiment, we consider that miR-107 expression is related to CVB3 infection. In order to further clarify the effect of miR-107 in the process of CVB3 infection, we studied the effect of miR-107 upstream and downstream target genes on CVB3 replication. Levels of the target RNAs were detected by RT-qPCR after CVB3 infection, and the expression of CVB3 capsid protein VP1 by western blot analysis. Then the virus in the supernatant was quantitated via a viral plaque assay, reflecting the release of the virus. The experimental results

Editorial comment: Cunningham and his associates determined whether enterovirus sequences were present in muscle biopsy specimens obtained from patients with PVFS. Two classes of probes were used: (i) so-called generic probes that were enterovirus group-specific; and (ii) probes that made it possible to determine whether virus RNA synthesis was asymmetrical (typical of cytic infection) or symmetrical (typical of defective viral RNA synthesis). Importantly, appropriate probes were used to test whether specimens also were positive for EBV sequences. Seventeen patients were studied that had fatigue for six or more months. Of these, five were mates and 13/17 were at midlife, i.e., 35-55 years of age. Then patients were tested for neutralizing antibody to Coxsackievirus B3; five were negative. Eleven patients were tested for IgM to Coxsackievirus B2, 3 and 5; of these, 10 were negative. Such results indicate that antibodies to Coxsackieviruses are not good surrogate markers for PVFS. When muscle ...

Who is at risk for hand, foot, and mouth disease?. Hand, foot, and mouth disease (HFMD) occurs mainly in children under 10 years old, but may occur in adults as well. HFMD is most common in children in child care settings, where diaper changing and potty training are constant and little hands are often in and out of the mouth frequently. Everyone is at risk for infection, but not everyone who is infected gets ill. Children are more likely to experience illness because they may not have immunity from a previous infection. Infection results in immunity to the specific virus, but a second episode may occur resulting from a different type of enterovirus. HFMD is more common in the summer and early autumn months. ...

A newly discovered virus seems to lack the proteins needed to replicate itself. Yet somehow, its thriving, according to a new study.. To find this mysterious virus, a group of researchers in Japan have spent nearly a decade analyzing pig and cow poop for novel viruses. These dirty environments, where lots of animals constantly interact, are a good place for viruses to quickly evolve, according to a statement from Tokyo University of Agriculture and Technology in Japan.. Related: 27 Devastating Infectious Diseases. The researchers have found on farms several novel viruses that have recombined - meaning that two or more viruses have swapped genetic material. But they were particularly intrigued when they found a new type of enterovirus G (EV-G), which is composed of a single strand of genetic material. This new virus was formed from an enterovirus G and another type, called a torovirus.. Mysteriously, the newly discovered microbe lacks a feature present in all other known viruses - so called ...
Eight of the nine children afflicted with paralysis are up to date on their polio vaccines.. Some are reported to be improving, and it remains unclear whether or not their paralysis will be permanent.. Some enteroviruses, including D68, have been shown in rare cases in the past to be capable of causing neurologic symptoms and sudden muscle weakness.. The virus can infect the central nervous system, causing injury to some of the cells and the spinal cord, and that is what actually leads to the paralysis, said Glatter.. The emergence of paralysis cases, so far only in Colorado, suggests it is possible that the virus may be mutating, he added.. It is not clear why some children are affected and others arent at this point. So it is an ongoing puzzle that we are hoping to solve in the near future, said Glatter.. Meanwhile, the outbreak is expanding fast. Earlier this month, the CDC said about a dozen states had reported cases. By the end of September, 40 states were implicated.. Enterovirus ...

Researchers have a leading suspect in mind for what may have caused the paralysis of more than 100 children in the United States since August 2014-but definitive evidence eludes them.. In a study published Jan. 28 in the medical journal The Lancet, researchers described evidence linking the paralysis to Enterovirus D68 (EV-D68). EV-D68 had already been a suspect because in a previous study, the virus was found in nasal swabs from 8 out of 41 paralysis patients tested, according to Nature. The new study focused on a group of children who experienced this paralysis in Denver, Col. In this smaller group, the link appeared strong. Nature reported: Nasal swabs from 8 of the 11 children affected contained enteroviruses, with 5 of them containing EV-D68. … However, the strongest proof that the virus underlies the paralysis would be if it were found in affected peoples cerebrospinal fluid.. It has not, however, been found in the cerebrospinal fluid.. (…) The Lancet reported that hospitals and ...
The CDC is investigating a possible link between EV-D68 and clusters of unexplained paralysis in children. A California doctor who has investigated similar cases of mystery paralysis sees a connection.
