Title
Malaria control through impregnated bednets - A pilot project in selected villages in Lao PDR
Abstract
In 7 villages on the foothills of the Houayxai district of the Bokeo Province in Lao PDR between midyear 1995 to midyear 1997 an attempt was made to test the acceptability and use of DDT impregnated bed nets as well as environmental and behavioral risk factors. About 380 women between 15 to 45 years old and their children in the age range of 1 to 14 years had been studied. A pre-tested questionnaire had been applied and blood from women and children was taken from the finger prick and a conventional thick and thin blood smear was performed, fixed Giemsa stained and examined for malaria parasites. DDT (dichlorodiphenyltrichloroethane) impregnated mosquito nets were distributed in the intervention villages. The availability of mosquito nets increased statistically significant from approximately 50% to 70% for all family members in the intervention area between 1995 and 1997 and statistically significant decreased in the control area from 79% to 45.1%. There was a statistically significant decrease in malaria attacks as claimed by the females for the intervention area but not for the control villages. The proportion of positive blood smears did decrease overall for women and children in between 1995 to 1997. Occupation, location of the house and use of mosquito nets had been determined as the most important risk factors.
