Viet Nam

00000000In Viet Nam since 1963, there has been a steady increase in the incidence of DHF. This was a major health problem and a leading cause of hospitalization and death for children. In Northern Viet Nam, DHF was identified for the first time in 1959, where a major epidemic occurred in 1969. At present most of the cases in the North are DF and affect adults more than children. In the South, DHF first appeared in 1960, then an outbreak has occurred in 1963 resulting in 331 hospitalized children with severe hemorrhage, of whom 116 died. Since then, the disease has been spreading with continuous increase in the number of cases and deaths, with the critical appearance of DEN 2 in 1987, then it was closely followed by DEN 1, Den 3 and DEN 4. Most of the cases in the South are DHF and affect mostly children under 15 years of age.
