The clinical manifestations and treatment of hand, foot and mouth disease caused by Coxsackievirus A6

Abstract

Hand-foot-and-mouth disease (HFMD) is a common infectious disease caused by human enterovirus (EVs). It is more common in children under 5 years of age.The clinical symptoms are mainly rash and herpes in the hands, feet, mouth and other parts.Some serious cases may suffer from serious complications in nervous system, respiratory system or circulatory system.Since 1998, HFMD has been mainly caused by enterovirus 71 and coxsackievirus A16 (CV-A16). In the past 10 years, coxsackievirus A6(CV-A6) has gradually replaced EV-71 and CV-A16, and become a main pathogen of HFMD.Many literatures have shown that CV-A6 often causes atypical HFMD, which is mainly characterized by a wider and more serious rash and desquamation, and even onychomadesis.At present, there are some reports on the prevalence and detection methods of HFMD caused by CV-A6.The paper reviewed on CV-A6 related etiology, epidemiology, clinical manifestations and treatment of HFMD.
