Over 60,500 dengue cases were reported in the state of Espírito Santo (ES), Brazil, between 1995 and 1998. The study's purpose was to identify whether Aedes albopictus was transmitting the dengue virus during an epidemic in the locality of Vila Beth nia (Viana County),Vitória, ES. From April 3 to 9, 1998, blood and serum samples were collected daily for virus isolation and serological testing. Four autochthonous cases were confirmed through DEN 1 virus isolation and two autochthonous cases through MAC ELISA testing. Of 37 Ae. aegypti and 200 Ae. albopictus adult mosquitoes collected and inoculated, DEN1 virus was isolated only from a pool of two Ae. aegypti female mosquitoes. The study results suggest that Ae. albopictus still cannot be considered an inter-human vector in dengue epidemics in Brazil.
1995年至1998年间，巴西圣埃斯皮里图州（ES）报告了超过60500例登革热病例。该研究的目的是确定在圣埃斯皮里图州维多利亚市维亚纳县的维拉贝尼亚地区发生疫情期间，白纹伊蚊是否传播登革热病毒。1998年4月3日至9日，每天采集血液和血清样本进行病毒分离和血清学检测。通过DEN 1病毒分离确诊了4例本地病例，通过MAC ELISA检测确诊了2例本地病例。在采集并接种的37只埃及伊蚊和200只白纹伊蚊成年蚊子中，仅从一组两只埃及伊蚊雌蚊中分离出了DEN1病毒。研究结果表明，在巴西的登革热疫情中，白纹伊蚊仍不能被视为人间传播媒介。
