The endemicity of schistosomiasis japonica in Sorsogon, Southeastern Luzon

ABSTRACT

For the first time, the endemicity of Schistosomiasis japonica in Irosin, Sorsogon has been definitely established, with the finding of both Oncomelania quadrasi snails and 22 human cases who had contracted the disease there. This is the first town in the island of Luzon so declared; and judging from conditions of climate and topography (low rice lands, and abundant streams) the neighboring towns of Juban and Bulan may also be marked as probable endemic fociIncidentally, it has also been found that paragonimiasis could be endemic in Irosin with the discovery of one case in a child of 7 years who had never left the town, and the presence of infected crabs in the place.
