Abstract

Aedes aegypti mosquitoes drive arboviral outbreaks in tropical regions. Zika virus (ZIKV), linked to congenital and neurologic complications, caused a major outbreak in Puerto Rico, USA, in 2016, infecting ≈26% of the population. Autocidal gravid ovitraps (AGOs), pesticide-free devices targeting gravid Ae. aegypti mosquitoes, have been shown to reduce transmission of another arbovirus, chikungunya. During March-May 2017, we conducted a household-based serosurvey in 4 demographically similar communities in southeastern Puerto Rico, 2 with long-term AGO deployment (≈85% coverage) and 2 without, to assess effects of AGOs on ZIKV transmission. Among 271 participants >5 years of age, ZIKV seroprevalence was much lower in intervention than nonintervention communities (9.6% vs. 20.0%). Protective effects were strongest among older adults, larger households (>4 persons), and persons spending more time at home. Although study design and measurement limitations could limit generalizability of results, our findings support AGOs as sustainable nonchemical tools for reducing ZIKV infections.

美国波多黎各自杀妊娠诱卵器预防寨卡病毒感染的效果评价。

埃及伊蚊在热带地区引发虫媒病毒暴发。与先天性和神经系统并发症有关的寨卡病毒（ZIKV）于2016年在美国波多黎各引起了一次重大疫情，感染了约26%的人口。自杀妊娠诱卵器（AGOs），针对妊娠伊蚊的无农药装置。埃及伊蚊已被证明可以减少另一种虫媒病毒基孔肯雅热的传播。2017年3月至5月期间，我们在波多黎各东南部4个人口统计学相似的社区进行了一项基于家庭的血清调查，其中2个长期部署了AGO（≈85%覆盖率），2个没有，以评估AGOs对寨卡病毒传播的影响。在271名5岁以下的参与者中，干预组的寨卡病毒血清患病率明显低于非干预组（9.6%对20.0%）。在老年人、大家庭（40人）和在家时间较长的人中，保护作用最强。尽管研究设计和测量的局限性可能会限制结果的普遍性，但我们的研究结果支持AGOs作为减少寨卡病毒感染的可持续非化学工具。

期刊介绍： Emerging Infectious Diseases is a monthly open access journal published by the Centers for Disease Control and Prevention. The primary goal of this peer-reviewed journal is to advance the global recognition of both new and reemerging infectious diseases, while also enhancing our understanding of the underlying factors that contribute to disease emergence, prevention, and elimination. Targeted towards professionals in the field of infectious diseases and related sciences, the journal encourages diverse contributions from experts in academic research, industry, clinical practice, public health, as well as specialists in economics, social sciences, and other relevant disciplines. By fostering a collaborative approach, Emerging Infectious Diseases aims to facilitate interdisciplinary dialogue and address the multifaceted challenges posed by infectious diseases.
