Abstract:
The virologic surveillance offered knowledge of epidemic stereotypes of dengue viruses inViet Nam during the years from 1987-2001. The activity cycle of Dengue-1 stared in 1989 and remained active until 1996. The Dengue-2 activity cycle began in 1987 and continued through 1997. While Dengue-3 first appeared in 1995 and presently continue to be active. Genomic structure of the Dengue-2/Viet Nam/1987 is somewhat different in comparision with several topotypes of the world, but closely related to the Dengue-2 topotype of Jamaica. Another sles relationship has been demonstrated between the Dengue-3/Viet Nam and the Dengue-3/ThaiLand/1987. In Southern Viet Nam, cases of dengue haemorrhagic fever are confirmed through virologic and serologic surveillance in the first quarter of each year
