Despite extensive research in vaccine development, there is at present no known method of controlling dengue except by the mosquito vectors. Virologic surveillance which involves the detection of dengue virus (DENV) in human serum and followed by isolation of virus using cell culture or mosquito inoculation is used as an early warning symptom to predict the outbreak. The technique is not much effective as the virus is in the human population. However, if the virus is detected in mosquito before it can infect humans could be more effective approach. One of the great mysteries about the epidemiology of dengue is how the virus persists in the interepidemic period. So far, no such studies on dengue vectors have been conducted in the north-eastern region of India, especially in Assam and the dengue cases are increasing every year. There are no reports on the identification of active and potential role of dengue vector responsible for the transmission of dengue in this state. Such type of study will give an overall picture of potential dengue vector responsible for human DENV infection and the viral load carried by the mosquito species in different generations. Such study will be useful in helping the public health personnel.
