Hemagglutination inhibition tests for antibody against chikungunya virus and the 4 dengue viruses were performed on a rural Thai village population. The 50 and 90% prevalence indices fell at .apprx. ages 3 and 15 yr for dengue virus exposure. This is a considerably earlier exposure than comparable urban populations. The prevalence of chikungunya virus antibody was also age-related with 50% prevalence at .apprx. 45 yr.
