[South-East Asian arboviruses (author's transl)]

Abstract

The South-East Asian arbovirological pathology is dominated by dengue fever, of which haemorrhagic forms constitute an important public health problem. The incidence of the disease is increasing from year to year, especially in large urban areas of this region and it is expected that the development of a vaccine in the near future will make it possible to improve the actual prevention only based on mosquito control, directed against domestic and peridomestic Aedes. Almost equally worrying is the epidemiological situation of Japanese encephalitis, which recently gave rise to important outbreaks in the Indian sub-continent, the transmission of which is ensured by rural mosquitoes and is very difficult to interrupt. Other arbovirus diseases are of secondary importance; they can involve dengue-like syndromes, meningo-encephalitic syndromes or haemorrhagic syndromes, and constitute public health problems only sporadically.
