Abstract

During the 1993 rainy season, 15,806 mosquitoes, including 14,304 Aedes ssp., were collected and tested for virus infection in 702 and 547 pools, respectively. Aedes furcifer (Edwards) was the most abundant species collected throughout the survey period. Yellow fever (YF) virus was detected in 187 pools: Ae. furcifer (123 isolates), Ae. taylori (Edwards) (41 isolates), and Ae. luteocephalus (Newstead) (23 isolates). A high prevalence of immunoglobulin (IgG) antibodies was found in human and simian populations. Results clearly indicated that increased sylvatic YF activity in eastern Senegal has the increased the risk of YF transmission among rural populations in West Africa. Our results showed that a minimal survey period may be effective in detecting the circulation of YF in the Kedougou area.

摘要

在1993年雨季，分别从702个和547个样本池中收集了15806只蚊子，其中包括14304只伊蚊属蚊子，并检测其病毒感染情况。在整个调查期间，富氏伊蚊（爱德华兹）是收集到的数量最多的蚊种。在187个样本池中检测到了黄热病（YF）病毒：富氏伊蚊（123个分离株）、泰勒伊蚊（爱德华兹）（41个分离株）和黄头伊蚊（纽斯特德）（23个分离株）。在人类和猴类群体中发现了高流行率的免疫球蛋白（IgG）抗体。结果清楚地表明，塞内加尔东部丛林型黄热病活动的增加提高了西非农村人口中黄热病传播的风险。我们的结果表明，最短的调查期可能有助于检测凯杜古地区黄热病的传播情况。
