Abstract:
In 1997, a big outbreak of DF/DHF occurred in the South of Viet Nam, especially in 3 provinces: Tra Vinh, Ca Mau and Kien Giang. Morbidity and mortality of the disease is highest in these provinces. Although ULV insecticide spray was carried out several times during the year, DF/DHF situation was not improved. Result of dengue vector surveillance shows that Breteau index of Ae.aegypti was from 5 to 11 times higher than dengue transmitting risk, 83-100% houses infecting with Ae.aegypti larvae. Key breeding sites of the mosquitoes were not affected by control activities are the main reason leading to persistence of DF/DHF in the areas.
