Abstract
A sero-epidemiological study was conducted in Solo (Central Java) and Pontianak (West Kalimantan) to compare the role of culex mosquitoes and pigs in transmitting the Japanese Encephalitis (J.E.) virus in the community. Data were obtained from 898 children at 6—7 y.o. using C.F. test, while light traps and mosquito larval collection gained from 235 houses in endemic and silent areas, and from 416 pigs collected from farmers, using H.I. test. The high infection rate against J.E. among children in Pontianak (44.4%) compared with in Solo (6.8%) was correlated with the higher infection rate (100.0%) and higher geometric mean of antibody titer (> 80) among pigs population rather than with the Culex density which was found high in both cities. Cx. gelidus was found only in Pontianak , but its role in transmission was not studied yet.
