Enterovirus 71 (EV71) frequently causes fatal infections in young children in Asia. In 2011, EV71 epidemics occurred in southern Vietnam. We conducted genetic and antigenic analysis of the EV71 isolates and found that 94% of them were genotype C4a related to two lineages circulating in China and 6% were genotype C5 which have circulated in Vietnam since 2003. Antigenic variants were not detected. EV71 vaccines are being developed. Longitudinal enterovirus surveillance data are critical to formulate vaccination policy in Vietnam.
肠道病毒 71 型（EV71）经常导致亚洲幼儿发生致命感染。2011 年，EV71 在越南南部爆发。我们对 EV71 分离株进行了遗传和抗原性分析，发现其中 94%为与中国流行的两个谱系相关的 C4a 基因型，6%为自 2003 年以来在越南流行的 C5 基因型。未检测到抗原变异体。EV71 疫苗正在开发中。在越南制定疫苗接种政策时，需要对肠道病毒进行长期监测。
