Methods:Blood samples were collected from 650 individuals distributed among six districts in East Timor.434 and 216 individuals were sampled by passive and active case detection, respectively(PCD,ACD).Results:The results showed that the plasmodium infection prevalence was 18.9%with predominance of Plasmodium falciparum(P.falciparum) infections(60.2%). The majority of cases were detected in children between 2-14 years old in both PCD and ACD. Participants residing in Same and Lospalos were at a higher risk of malaria.The percentage of infections associated to the lack of bed net use was twice as high as users(25.2%vs 12.5%). The prevalence of malaria among participants who lived in brick/cement houses(8.3%) was two times less than those who lived in other types of houses(3.7%).There was a significantly lower prevalence of infection detected in individuals living in complete housing constructions with absence of domestic animals in or near the houses.Conclusions:The major risk factors for malaria in East Timor are age,lack of bed net use,incomplete housing constructions and exposure to mosquitoes.展开更多
