Abstract
Human enteroviruses are classified into four species (A, B, C, and D) and include over 100 serotypes. Except polioviruses and enterovirus A71 (EV71) which frequently cause neurological complications, human enteroviruses usually cause self-limited infections. EV71 was first identified and a large-scale EV71 epidemic was documented in southern Vietnam in 2003 which reported 173 EV71 cases, including 51 with neurological complications and 3 fatal cases. In 2011, a large-scale EV71 epidemic occurred with more than 5,000 inpatients and 32 fatal cases in CH1, HCM. NHRI cooperated with CH1 to establish hospital-based surveillance of enterovirus in HCM City in 2011. Inpatients <0.5 years of age to 17.2, 24.0, 29.4, 58.6 at 0.5-0.9, 1-1.9, 2-2.9, 3-3.9 and 4-4.9 years of age, respectively. Risk of EV71 infections in Vietnam increased after 6 months of age. Vietnamese children in HCM City acquired EV71 infections at an early age and vaccine development in Vietnam should target young children.
