Zika virus is a mosquito-borne flavivirus primarily transmitted by Aedes aegypti mosquitoes (1,2). Infection with Zika virus is asymptomatic in an estimated 80% of cases (2,3), and when Zika virus does cause illness, symptoms are generally mild and self-limited. Recent evidence suggests a possible association between maternal Zika virus infection and adverse fetal outcomes, such as congenital microcephaly (4,5), as well as a possible association with Guillain-Barré syndrome. Currently, no vaccine or medication exists to prevent or treat Zika virus infection. Persons residing in or traveling to areas of active Zika virus transmission should take steps to prevent Zika virus infection through prevention of mosquito bites (http://www.cdc.gov/zika/prevention/).
Zika 病毒是一种蚊媒黄病毒，主要由埃及伊蚊传播（1,2）。据估计，80%的 Zika 病毒感染病例无症状（2,3），当 Zika 病毒确实引起疾病时，症状通常较轻且自行限制。最近的证据表明，母体 Zika 病毒感染与不良胎儿结局之间可能存在关联，例如先天性小头畸形（4,5），以及与吉兰-巴雷综合征之间可能存在关联。目前，尚无疫苗或药物可用于预防或治疗 Zika 病毒感染。居住在或前往 Zika 病毒传播活跃地区的人应采取措施通过预防蚊虫叮咬来预防 Zika 病毒感染（http://www.cdc.gov/zika/prevention/）。
