The seroprevalence of human herpesvirus 6 (HHV‐6) infection was examined for 434 Brazilians and 250 Japanese immigrants living in Recife and its vicinity, in the North‐East of Brazil. A total of 684 sera from the healthy individuals were screened for IgG antibodies to HHV‐6 by anticomplement immunofluorescence (ACIF) test. The seropositivity rate to HHV‐6 showed little difference between the two groups: namely, it was 76.5% for Brazilians and 77.2% for Japanese immigrants. The seropositivity rate was constantly higher in females than in males. The high prevalence of anti‐HHV‐6 antibodies among children indicates that HHV‐6 infection occurs very early in life.
