Dengue Virus 3 Genotype I inAedes aegyptiMosquitoes and Eggs, Brazil, 2005–2006

Abstract

Dengue virus type 3 genotype I was detected in Brazil during epidemics in 2002–2004. To confirm this finding, we identified this virus genotype in naturally infected field-caught Aedes aegypti mosquitoes and eggs. Results showed usefulness of virus investigations in vectors as a component of active epidemiologic surveillance.

Vertical Transmission of Dengue Virus in Aedes aegypti Collected in Surabaya, Indonesia, during 2008^|^ndash;2011

“…This mechanism is particularly important for maintenance of the virus, because mosquito eggs are capable of surviving in the environment even under adverse conditions for long periods, sometimes for more than a year (6). Vertical transmission in Aedes aegypti L., the principal vector for DENV1-4, has been proven experimentally (5,(7)(8)(9) and in the field (10)(11)(12)(13)(14). However, the extent to which vertical transmission affects the percentage of infected Ae.…”

Infection of the central nervous system with dengue virus 3 genotype I causing neurological manifestations in Brazil

“…Our laboratory has isolated and characterized DENV-3 genotype I from patients and mosquitoes in different cities of Minas Gerais (Figure 1), most recently (2013) in Contagem, MG (unpublished data) (6) (7) . The patients presented with a wide range of clinical manifestations including headache, light sensitivity, retro-orbital pain, general body pain (arthralgia, myalgia), vomiting, and hemorrhage (6) .…”

Towards a Casa Segura: A Consumer Product Study of the Effect of Insecticide-Treated Curtains on Aedes aegypti and Dengue Virus Infections in the Home

“…aegypti females is feasible, and thus can serve as the basis for viable virological outcome measures in intervention studies. 9,22,[53][54][55][56][57][58] In conclusion, the longevity of Ae. aegypti, its penchant for feeding frequently on humans even in a single gonotrophic cycle, and its preference for feeding on humans in domiciles and in bedrooms where DENV-infected humans typically are cared for and visited by friends and relatives make it a public health imperative to control the mosquito in the home and other indoor environments.…”
