The management of hand-foot-and-mouth disease(HFMD) epidemic is difficult due to the frequent emergence of non-EV71 and non-CVA16 enteroviruses and some cases testing negative for HFMD-associated causative agents. To clarify the virus spectrum of mild and severe HFMD, a comprehensive virome analysis of 238 samples was performed using next-generation sequencing (NGS). The data revealed total thirteen mammalian- and plant- virus families and diverse viral populations including enteroviruses, common respiratory viruses, diarrhea-related viruses, plant viruses and anelloviruses...

Coxsackievirus A10 (CVA10) has emerged worldwide as one of the main pathogens of hand, foot, and mouth disease (HFMD) in recent years. However, there is currently no commercial vaccine available to prevent CVA10 infection. Here we report the development of a recombinant virus-like particle (VLP) based candidate vaccine for CVA10. Co-expression of the capsid protein precursor P1 and the protease 3CD of CVA10 in Pichia pastoris resulted in cleavage of P1 into three capsid subunit proteins VP0, VP1, and VP3. These three subunit proteins co-assembled into CVA10 VLPs, which were visualized as spherical particles with a diameter of ∼30 nm under electron microscope...

Bullous pemphigoid (BP) is an immune mediated bullous disease that is manifested by urticarial plaques with superimposed subepidermal blisters and significant pruritus. It is generally found in the elderly, but is rare in the pediatric population. A 5-month-old girl previously diagnosed with hand-foot-mouth disease was examined in our dermatology department owing to vesicles and bullae, initially located to the hands and feet, which progressed with new lesions. Tense vesicles and bullae distributed in an annular string of pearls pattern on the abdomen and facial and cervical regions were noted...

Fibronectin (FN) is a high molecular weight extracellular matrix protein that contains RGDS motif, which is required to bind to integrins. Synthetic RGDS peptides have been reported to compete with FN to bind to the cell surface and inhibit the function of FN. Here, we identified that synthetic RGDS peptides significantly inhibit human enterovirus 71 (EV71) infection in cell cultures. In addition, mice treated with RGDS peptides and infected with EV71 had a significantly higher survival rate and a lower viral load than the control group...

BACKGROUND: As a common infectious disease, hand, foot and mouth disease (HFMD) is affected by multiple environmental and socioeconomic factors, and its pathogenesis is complex. Furthermore, the transmission of HFMD is characterized by strong spatial clustering and autocorrelation, and the classical statistical approach may be biased without consideration of spatial autocorrelation. In this paper, we propose to embed spatial characteristics into a spatiotemporal additive model to improve HFMD incidence assessment...

Enterovirus 71 (EV71) is the primary pathogen of hand-foot-and-mouth disease (HFMD) in children and virus infections are associated with severe neurological dysfunctions and even death. MIR2911 is a honeysuckle-encoded atypical microRNA with extremely stability. Here, we report that MIR2911 directly inhibits EV71 replication by targeting the VP1 gene. Bioinformatics prediction and luciferase reporter assay showed that MIR2911 could target the VP1 gene of EV71. Transfection experiments using synthetic MIR2911 and extracted RNA from HS decoction shown that each of these preparations was capable of inhibiting EV71 VP1 protein expression; however, these preparations did not impact EV71 mutants in which the MIR2911-binding sites were mutated...

Enterovirus 71 (EV71) and coxsackievirus A16 (CA16) are two major etiologic agents associated with hand, foot, and mouth disease (HFMD) worldwide. Despite that they both belong to the Enterovirus genus of the Picornaviridae family, there are many differences in the infection process of these viruses. However, the underlying mechanisms have not been elucidated. Multiple studies indicated that microRNAs (miRNAs) can play critical roles in the host-pathogen interaction. Our previous study reported that EV71 and CA16 infection leads to differential expression of miRNAs in human bronchial epithelial (16HBE) cells...

Enterovirus 71 (EV71) is the primary causative pathogen of hand, foot, and mouth disease (HFMD), affecting children with severe neurological complications. Pyroptosis is a programmed cell death characterized by cell lysis and inflammatory response. Although proinflammatory response has been implicated to play important roles in EV71-caused diseases, the involvement of pyroptosis in the pathogenesis of EV71 is poorly defined. We show that EV71 infection induced caspase-1 activation. Responding to the activation of caspase-1, the expression and secretion of both IL-1β and IL-18 were increased in EV71-infected cells...

Enterovirus A71 (EV-A71), coxsackievirus A16 (CV-A16), and CV-A6 are the major causative agents of Hand-foot-and-mouth disease (HFMD). These viruses belong to the species Enterovirus A of the genus Enterovirus of the family Picornaviridae. These viruses can also cause aseptic meningitis (AM), encephalitis and/or paralysis. EV-A71 is one of the main infectious agents related to severe encephalitis. Between 1997 and 2013, East and Southeast Asia experienced large encephalitis outbreaks caused by EV-A71 infections, which ranged from severe to lethal...

Hand, foot and mouth disease (HFMD) is a serious public health problem, and coxsackievirus A6 (CVA6) and coxsackievirus A10 (CVA10) are two of the major causative pathogens, in addition to enterovirus 71 (EV71) and coxsackievirus A16 (CVA16). A simple and rapid reverse transcription recombinase-aided amplification assay (RT-RAA) was developed for the detection of CVA10 and CVA6 in this study. The analytical sensitivity for detection of CVA10 and CVA6 at 95% probability by probit regression analysis was 35 copies per reaction and 38 copies per reaction, respectively, with 100% specificity...

Human enterovirus 71 (EV71) is the second most common cause of hand, foot, and mouth disease (HFMD), which can occur as a severe epidemic especially among children under 5-years old. New and improved treatment strategies to control EV71 infection are therefore urgently required. The heterocyclic compound GS-9620, a potent and selective agonist of Toll-like receptor 7 (TLR7), has been reported to activate plasmacytoid dendritic cells (pDCs), and suppress HBV as well as HIV replication. In this study, we indicated that GS-9620 also could inhibit EV71 replication in the mouse model of EV71 infection...

Susanna Esposito, Nicola Principi
For a long time, hand, foot and mouth disease (HFMD) was seen as a mild viral infection characterized by typical clinical manifestations that spontaneously resolved in a few days without complications. In the past two decades, HFMD has received new attention because of evidence that this disease could have clinical, epidemiological and aetiological characteristics quite different from those initially thought. In contrast to previous beliefs, it has been clarified that HFMD can be associated with complications, leading to severe neurological sequelae and, rarely, to death...

BACKGROUND: Hand, foot, and mouth disease (HFMD) has become an emerging infectious disease in China in the last decade. There has been evidence that meteorological factors can influence the HFMD incidence, and understanding the mechanisms can help prevent and control HFMD. METHODS: HFMD incidence data and meteorological data in Minhang District, Shanghai were obtained for the period between 2009 and 2015. Distributed lag non-linear models (DLNMs) were utilized to investigate the impact of meteorological factors on HFMD incidence after adjusting for potential confounders of long time trend, weekdays and holidays...

Hand, foot and mouth disease (HFMD) is a substantial burden throughout Asia, but the effects of temperature pattern on HFMD risk are inconsistent. To quantify the effect of temperature on HFMD incidence, Wuhan was chosen as the study site because of its high temperature variability and high HFMD incidence. Daily series of HFMD counts and meteorological variables during 2010-2015 were obtained. Distributed lag non-linear models were applied to characterize the temperature-HFMD relationship and to assess its variability across different ages, genders, and types of child care...

Hand, foot, and mouth disease (HFMD), usually a self-limiting illness for young children, could cause a significant burden for parents because it can take up to 1-2 weeks for a sick child to recover. We conducted a two-wave longitudinal study over one summer peak season (May-July 2014) of HFMD to examine parents' HFMD-related risk perceptions and protective responses. In total, 618 parents with at least one child aged ⩽12 years, recruited using randomly-dialled household telephone calls completed the baseline survey interview, 452 of whom subsequently completed the follow-up survey...

Enterovirus 71 (EV71) is a major pathogen that causes hand, foot and mouth disease (HFMD) as well as neurological complications, such as encephalitis. The chemokines involved in the migration of leukocytes have increasingly been implicated in infectious diseases of the central nervous system. Few studies have evaluated the levels of chemokines in HMFD children with EV71-related encephalitis. In the present study, we evaluated the cerebrospinal fluid (CSF) levels of the chemokines IL-8, RANTES, MIG, MCP-1 and IP-10 in 99 children with EV71-related encephalitis and 22 children with febrile convulsion (FC)...
