BACKGROUND
We report results of the entomo-virological surveillance system in Aedes aegypti local populations performed by the Ministry of Health of Guerrero.
METHODS
Indoor-adult Ae. aegypti collected at Acapulco, Zihuatanejo, Coyuca de Benitez and Atoyac de Alvarez (dry season, 2015) were processed for dengue virus (DENV) and chikungunya virus (CHIKV) using RT-PCR.
RESULTS
We identified different seroptypes of DENV (2, 3 and 4), CHIKV and their co-circulation in field-caught mosquitoes across a significant geographic area. Pools of males were positive for CHIKV and DENV 3 and 4 suggesting vertical transmission.
CONCLUSIONS
Entomo-virological surveillance in Guerrero has identified early circulation of CHIKV and DENV and provided a trigger for timely and focalized vector control actions.
背景
我们报告了格雷罗州卫生部对埃及伊蚊当地种群开展的昆虫病毒学监测系统的结果。
方法
于2015年旱季在阿卡普尔科、锡瓦塔内霍、科尤卡·德·贝尼特斯和阿托亚克·德·阿尔瓦雷斯采集的室内成年埃及伊蚊，采用逆转录聚合酶链反应（RT-PCR）检测登革病毒（DENV）和基孔肯雅病毒（CHIKV）。
结果
我们在一个重要地理区域内野外捕获的蚊子中鉴定出了不同血清型的登革病毒（2型、3型和4型）、基孔肯雅病毒及其共同传播情况。雄性蚊子样本对基孔肯雅病毒以及登革病毒3型和4型呈阳性，提示存在垂直传播。
结论
格雷罗州的昆虫病毒学监测已发现基孔肯雅病毒和登革病毒的早期传播，并为及时和有针对性的病媒控制行动提供了触发因素。
