Abstract
The serological status to cytomegalovirus (CMV) was examined for 616 Brazilians and 399 Japanese immigrants living in the North-East of Brazil. The sera were screened for IgG antibodies to CMV by enzyme-linked immunosorbent assay (ELISA). The overall prevalence of CMV antibodies was higher in the Japanese population (83.7%) than in the Brazilian population (69.8%). The seropositivity was analyzed by factors of age, sex, ethnic background, and socioeconomic status. Mother-baby contact seems to be a factor of significance in the seroepidemiology of CMV infection.
