RESUMO
The purpose of this study is to document the potential feasibility of using a bed net impregnation program to enhance the control of Malayan filariasis in southern Thailand. A survey was conducted in one Muslim and one Buddhist village along the swamp forest in Narathiwat Province. Face-to-face interview was employed to collect data on practice of bed net use, knowledge and attitudes on filarial control and acceptance if a bed net impregnation program were to be introduced. Bed nets were used by 98.5% of the study households. Both Muslims and Buddhists were all in bed by 23.00 hrs. By 03.00 hrs, more than 20% of Buddhists were out of bed for rubber tapping, whereas more than 90% of the Muslim were still in bed until 04.30 hrs. Combining our data with biting rate from a previous study, approximately one-third of Mansonia bites were protected by the current bed net practice. The impregnation program was potentially welcome by both groups of villagers. From this study, we conclude that a bed net impregnation program in this area is feasible.
