Epidemiology
B. malayi infects 13 million people in south and southeast Asia and is responsible for nearly 10% of the world’s total cases of lymphatic filariasis. B. malayi infection is endemic or potentially endemic in 16 countries, where it is most common in southern China and India, but also occurs in Indonesia, Thailand, Vietnam, Malaysia, the Philippines, and South Korea. The distribution of B. malayi overlaps with W. bancrofti in these regions, but does not coexist with B. timori. Regional foci of endemicity are determined in part by the mosquito vectors (see Transmission).
