Abstract
-Aedes aegypti is the principal epidemic vector of dengue viruses, responsi ble for a viral infection that has become a major public health concern in Asia. In Vietnam, dengue haemorrhagic fever was detected in the 1950s and b ecomes today one of the first causes of hospitalization and death among chi ldren in most Asian countries. In South-East Asia, urban centers expanded r apidly in an uncontrolled and unplanned way. The Ae. aegypti populations an d dengue viruses thrived in these new ecological and demographic settings. The result of these changes was a greatly extended geographic distribution, increased densities of Ae. aegypti and the maintenance of the four dengue serotypes in most urban centers of South-East Asia. The result of these cha nges was the dramatic increase of dengue transmission. To assess the role o f the vector in the changing pattern of the disease in South-East Asia, we studied the ecology of Ae. aegypti, the genetic differentiation, the variab ility in competence as a vector for dengue 2 virus and the resistance to in secticides.
