Getting dengue from vector mosquito bite at home: a reappraisal on chance based on molecular epidemiology data in Indochina.

Abstract

Dengue is an important vector borne viral infection. At present, it is endemic in many tropical countries. A molecular epidemiology of viral type in patients and mosquitoes can give useful epidemiology data for disease control. In Indochina, dengue is very common and the molecular epidemiology surveillance is continuously performed. Here, the authors reappraise on available local data from epidemiology studies of viral type in patients and mosquitoes in an endemic area of dengue in Indochina. According to analysis, the authors found that a considerable number of dengue patients do not have the same viral type with caught mosquito vector at their home. According to this study, a chance that a dengue patient gets pathogen from mosquito bite at home is 2.185%. The chance of getting dengue from the vector mosquito bite at home is not high. Hence, a public health policy to control of mosquito vector at home has to extend to universal control at any public places.
