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.
