Hand, foot and mouth disease (HFMD) is a global health concern. Family Picornaviridae members, particularly enterovirus 71 (EVA71) and Coxsackievirus A16 (CVA16), are the primary etiological agents of HFMD, however, a third enterovirus A species, CoxsackievirusA6 (CVA6), has been recently associated with epidemic outbreaks. Study of the pathogenesis of CVA6 infection and development of antivirals and vaccines are hindered due to the lack of appropriate animal models. We have developed and characterized a murine model of CVA6 infection which was employed to evaluate the antiviral activities of different drugs and the protective efficacies of CVA6-inactivated vaccines...

Enteroviruses (EVs) are associated with a broad spectrum of clinical presentation, including aseptic meningitis (AM), encephalitis, hand, foot and mouth disease, acute flaccid paralysis and acute flaccid myelitis. Epidemics occur sporadically and are associated with increased cases of AM in children. The present study describes the seroepidemiological analysis of circulating EVs in Ireland from 2005-2014 and phylogenetic characterisation of echovirus 30 (E-30), enterovirus A71 (EV-A71) and enterovirus D68 (EV-D68)...

Enterovirus (EV) has over 100 serotypes of species A-D, which can cause various symptoms in infants. Enterovirus encephalitis (EVE) is serve disease with high morbidity and mortality in children. To well define the epidemiology of EVE, we wanted to know more about EV and EV molecular typing by conducting this study in Hangzhou.Cerebrospinal fluid samples were collected from children with diagnosis of encephalitis. Meanwhile, one-step real-time RT-PCR was used for the detection of EV, and we also identified the serotypes of EV by using gene sequencing of VP1 or 5'UTR region...

Since the outbreak of the enterovirus 71 (EV71) infection in Malaysia in 1997, large epidemics of EV71 have occurred in the Asia-Pacific region. Many children and infants have died from serious neurological complications during these epidemics, and EV71 infection has become a serious public health problem in these areas. EV71 infection causes hand, foot and mouth disease (HFMD) in children, and usually resolves spontaneously. However, EV71 occasionally involves the central nervous system (CNS), and induces diverse neurological complications such as brainstem encephalitis, aseptic meningitis, and acute flaccid paralysis...

The epidemiology and clinical association of enterovirus (EV) and parechovirus (HPeV) infections, as well as the type-distribution-according-to-age, were determined during a 4-year study period in Spain. During 2010-2013, a total of 21,832 clinical samples were screened for EV and the detection frequency was 6.5% (1,430). Of the total EV-negative samples, only 1,873 samples from 2011 to 2013 were available for HPeV testing. HPeV was detected in 42 (2%) of them. Positive samples were genotyped using PCR and sequencing...

Enterovirus 71 (EV71) is a major threat to children worldwide. Children infected with EV71 could develop subclinical infection and hand-foot-and -mouth disease (HFMD). In severe cases, patients could develop encephalitis, paralysis, pulmonary edema, and death. A more user-friendly and robust animal model is essential to investigating EV71 pathogenesis. Here, we established a hybrid (hSCARB2(+/+)/stat-1(-/-)) mouse strain from crossbreeding SCARB2 transgenic and stat-1 KO mice, and compared the susceptibilities to EV71 infection and pathogenesis between parental and hybrid mice...

UNLABELLED: Hand, foot, and mouth disease (HFMD) has spread throughout the Asia-Pacific region, affecting millions of young children, who develop symptoms ranging from painful blisters around their mouths and hands to neurological complications. Many members of the genus Enterovirus (family Picornaviridae) cause HFMD. Enterovirus 71 (EV71) is one of the primary causative agents and has been linked to severe disease. Vaccine efficacy and pathogenesis studies for EV71 have been limited because there is a lack of suitable animal models...

Hand, foot, and mouth disease (HFMD) is a contagious viral disease and mainly affects infants and young children. The main manifestations are fever, vesicular rashes on hand, feet and buttocks and ulcers in the oral mucosa. Usually, HFMD is self-limiting, but a small proportion of children may experience severe complications such as meningitis, encephalitis, acute flaccid paralysis and neurorespiratory syndrome. Historically, outbreaks of HFMD were mainly caused by two enteroviruses: the coxsackievirus A16 (CV-A16) and the enterovirus 71 (EV-A71)...

Levetiracetam is a relatively novel antiepileptic drug used for the treatment of partial and generalized seizures in adult and children. Several animal studies describe a possible drug adverse effect on skeletal growth and metabolism. We present a case report of a 10-year-old female child who underwent a prolonged 7-year treatment with levetiracetam for sporadic secondary convulsions secondary to enterovirus encephalitis at the age of 15 months. This patient developed an osteochondritis dissecans lesion (OCD) of the talar head well treated conservatively...
