ABSTRACT

This was a descriptive cross sectional study. It was done in 4 communes along the Vietnam-Lao PDR border of two mountainous provinces Sonla and Nghean. The cluster multistage sampling technique was applied to choose the study sites. The results of the study show Among the 2,441 persons given blood tests to find malaria parasites, 0.7% of them carry malaria parasite, of whom 0.6% carry P. falciparum and 0.1% carry P. vivax. The malaria morbidity in the year was 6.9%. The mortality due to malaria is 1.59 per 100,000 population per year. Among the 106 hamlet motivators being interviewed, only 75.5% knew that malaria is transmitted by mosquitos, 71.7% knew that malaria patients are a source of transmission, over 50% of the motivators have mistaken understanding about the living environment of malaria mosquitos. Most of them have had mistakes in diagnosis, treatment of malaria, mosquito-killing spraying. Among the 729 adults being interviewed, 59.0% did not know about the causes of malaria, 30.7% did not take part in malaria control activities. Only 69.3% of the adults regularly sleep inside mosquito nets, 68% of adults buy medicine to cure malaria, 39.9% referred patients to health facilities for cure, and 25% use forest herbs to cure malaria. The factors that increased the malaria morbidity in communes along Vietnam-Lao PDR border have been identified.
