大部分患者无症状；然而，约有 20% 的感染会导致轻度和自限性的发热、皮疹和结膜炎。
有很强的科学共识认为，寨卡病毒是引起小头畸形和一些其他先天性畸形的病因。所观察到的异常程度与病毒间可能的因果关系表明可能存在一种新的先天性综合征。不建议孕妇前往寨卡病毒疫区，且应仔细考虑前往有寨卡病毒传播风险地区的风险。
格林-巴利综合征以及其他神经系统疾病与寨卡病毒相关性很高，且疑似由寨卡病毒引起，但其中的关联尚未证实，关于此的研究正在进行中，包括阐明其中可能的机制。
症状性感染的治疗主要为支持性治疗，且在这个阶段还没有特异性抗病毒疗法。通过个人和公共卫生手段预防蚊子叮咬是预防感染的重要方式。
由寨卡病毒（又称 ZIKV）引起的感染，当有症状时（发生于约 20% 的感染）表现为轻度且通常为自限性。寨卡病毒属于黄病毒科（黄病毒属），且为虫媒病毒（由节肢动物传播的病毒）。该病毒以 1947 年首次发现它的乌干达寨卡丛林命名。[1]Kindhauser MK, Allen T, Frank V, et al. Zika: the origin and spread of a mosquito-borne virus. Bull World Health Organ. 2016 Sep 1;94(9):675–86C.

寨卡病毒最初由伊蚊传播给人类，伊蚊同时也是登革热、基孔肯雅热和西尼罗河病毒的传播媒介。也有可能在人类之间经性传播。
发现先天性寨卡综合征是一种由孕期感染寨卡病毒所致的婴儿先天性异常（即，小头畸形、颅内钙化或其他脑部异常、或眼部异常等）。[2]Adebanjo T, Godfred-Cato S, Viens L, et al.
