We investigated dengue and chikungunya virus antibody seroprevalence in French Polynesia during 2014-2015. Dengue virus seroprevalence was ≈60% among schoolchildren and >83% among the general population; chikungunya virus seroprevalence was <3% before and 76% after Zika virus emergence (2013). Dengue virus herd immunity may affect Zika virus infection and pathogenesis.
我们调查了 2014-2015 年法属波利尼西亚的登革热和基孔肯雅热病毒抗体血清流行率。在学童中,登革热病毒血清流行率约为 60%,在普通人群中>83%;在寨卡病毒出现之前(2013 年),基孔肯雅热病毒血清流行率<3%,而在寨卡病毒出现后为 76%。登革热病毒群体免疫力可能影响寨卡病毒感染和发病机制。
