Summary : Activities used to control malaria transmission in the pilot station of Vanh Canh in the Binh Dinh Province of central Vietnam from 1976 to 1991 have been evaluated. These activities were: spraying DDT in and around the houses in the villages and the settlements in the fields\; spraying lambdacyalothrin in the houses\; and use of bed-nets impregnated with permethrin. Their efficacy was measured by the number of fever episodes due to malaria infections among the population. The spraying of DDT in the houses was followed by a reduction of malaria infection by more than 90%. However, spraying of the settlements was not advantageous. The termination of DDT spraying was not followed by an increase of malaria infections. Spraying with lambdacyalothrin was slightly more effective than with pyrimiphos and DDT. The use of pesticide-impregnated bed-nets was efficient, especially in the villages far away from the forest. Thus, these activities can contribute to the control of the malaria endemic in central Vietnam. |
