The emergence of Zika created a panic situation worldwide and burdened the public health system of the affected countries. In India, Zika outbreak occurred in 2017 and in July 2021 one laboratory-confirmed case was also reported in Kerala state. The study aimed to assess any positivity in field-collected mosquitoes for ZIKV and DENV during 2016-2021. Mosquito samples were received from 4 Zika affected citites, whereas samples were collected from Delhi. Out of 2346 pools, 4 pools for ZIKV, and 23 pools for DENV were found positive. ZIKV positive pools were from Shastri Nagar, Jaipur (2 pools), Rajpur Hotel, Jaipur (1 pool) and Kanpur (1 pool). Ten localities of Delhi were found positive for DENV. It was observed that the maximum positivity rate for both viruses were found in September-October. The active role of the vector in local transmission of ZIKV warrants regular surveillance and monitoring of Aedes vectors in India.
寨卡病毒的出现在全球范围内引发了恐慌，并给受影响国家的公共卫生系统带来了负担。在印度，寨卡病毒疫情于 2017 年爆发，2021 年 7 月，喀拉拉邦也报告了一例实验室确诊病例。本研究旨在评估 2016 年至 2021 年期间从现场采集的蚊子中寨卡病毒 (ZIKV) 和登革热病毒 (DENV) 的任何阳性情况。蚊子样本来自 4 个寨卡病毒感染城市，而来自德里的样本是采集的。在 2346 个池中，有 4 个池对 ZIKV 呈阳性，23 个池对 DENV 呈阳性。ZIKV 阳性池来自斋浦尔的沙斯特里纳加尔（2 个池）、拉杰普尔酒店（1 个池）和坎普尔（1 个池）。德里的 10 个地方对 DENV 呈阳性。观察到这两种病毒的最高阳性率都出现在 9 月至 10 月。病媒在寨卡病毒本地传播中的积极作用，要求印度定期对埃及伊蚊进行监测和监控。
