The purpose of this review was to summarize the epidemiology, clinical pictures, and virology of enterovirus 71 (EV71) infection. An epidemiological study in Taiwan revealed that the reported incidence of mild cases of hand-footmouth disease/herpangina (HFMD/HA) varied from year to year; seasonal variations in incidence were observed, with an incidence peak observed during the summer season. The study also showed that different enteroviruses co-circulate in the community, and seroepidemiological studies suggest that children aged less than 4 years old are most susceptible, while over 50% of the rest of the population is immune. The emergence of the EV71 epidemic in the Asia Pacific region has been associated with the circulation of three genetic lineages (genotype B3, B4, C2) that appear to be undergoing rapid evolutionary changes. EV 71 infection has emerged as an important public problem, causing serious clinical illness and, potentially, death in young children. Vaccine development is recommended for the prevention of EV 71 infection in the future.
