Abstract:
Epidemiological characteristics of Dengue hemorrhagic fever (DHF) in the High-Plateaux were assessed using data from the national DHF control project and the results of viral isolation and serologic surveillance between 1998 - 2004. From 1998 to 2004, the number of epidemics was decreasing. Main forms of DHF I&II accounted for 86.90%. The majority of epidemics occurred in Buon Ma Thuot city and Pleiku city. Some epidemics has occurred in others districts in the High-Plateaux from 1999 to 2004 at mild degrees. Interestingly, the main types of DHF were Dengue virus type 3 in 1998, Dengue virus type 2 in 2002, and Dengue virus type 1 in 2004. The seropositive rate was high (35.02 - 40.78%) and primarily infected patients were predominant (57.75 - 76.70%).
