Abstract Sera from inhabitants of Belém, Pará (542 sera), Brazil and of members of 3 Brazilian tribes—Tiriyo/Alto Paru (near Surinam) (212 sera), Xicrin (128 sera), and Mekranoiti (121 sera)—of different age and sex groups were tested for the presence of specific antibody against human parvovirus (B19) (RIA) and rubellavirus (latex agglutination test). Parvovirus (B19) IgG was found in 42.6% of the population sample from Belém but in only 4.7 to 10.7% of the members of the tribes. Rubellavirus antibody was found in 72.7% of the sera from Belém but approaching a prevalence of 85–90% in age groups above 20 years. In the tribes rubellavirus antibody was detected in 36.9 to 72.6% of all sera. There were remarkable sex differences of antibody prevalence in several age groups of the population from Belém and of the tribal populations. About a quarter of the skin rashes in Belém that were not attributable to infections with rubella, measles, or arboviruses were caused by recent B19 infections.
