Abstract:
In 2 epidemics of Dengue haemorrhagic fever in Bien Hoa, the predominant serotypes of dengue virus in the year 2000 and 2003 were Dengue-4 and Dengue-1, respectively. The number of clinical cases of children under 15 years old diagnosed as viral infection and unknown fever (n=1653), were higher than those diagnosed as Dengue fever/Dengue haemorrhagic fever (DF/DHF) (n=1122). The number of Dengue virus isolated from patients with viral infection and unknown fever (n=102) was higher than those isolated from DF/DHF cases (n=85). The number of Dengue positive MAC-ELISA cases in 2 years was 870 corresponding to a positive rate of 30.27%
