The sudden appearance of overt human Zika virus infections that cross the placenta to damage fetal tissues, target sexual organs, and are followed in some instances by Guillain-Barré syndrome raises questions regarding whether these outcomes are caused by genetic mutations or if prior infection by other flaviviruses affects disease outcome. Because dengue and Zika viruses co-circulate in the urban Aedes aegypti mosquito-human cycle, a logical question, as suggested by in vitro data, is whether dengue virus infections result in antibody-dependent enhancement of Zika virus infections. This review emphasizes the critical role for epidemiologic studies (retrospective and prospective) in combination with the studies to identify specific sites of Zika virus infection in humans that are needed to establish antibody-dependent enhancement as a possibility or a reality.
人类寨卡病毒显性感染突然出现,该病毒可穿过胎盘损害胎儿组织、侵袭性器官,且在某些情况下会引发吉兰-巴雷综合征,这引发了关于这些后果是由基因突变导致,还是先前感染其他黄病毒影响疾病结果的疑问。由于登革热病毒和寨卡病毒在城市埃及伊蚊-人类传播循环中共同流行,正如体外数据所表明的,一个合乎逻辑的问题是,登革热病毒感染是否会导致寨卡病毒感染的抗体依赖性增强。本综述强调了流行病学研究(回顾性和前瞻性)与确定人类寨卡病毒感染特定部位的研究相结合的关键作用,这些研究对于确定抗体依赖性增强是否可能或确实存在是必要的。
