Freitas, Ronaldo Barros de
Linhares, Alexandre da Costa
A total of 497 serum samples obtained from residents of 2 neighbourhoods (Terra-Firme and Guamá) in Belém, Pará, Brazil was tested for the presence of antibody to human herpesvirus 6 (HHV6), using an indirect immunofluorescence assay. The overall seroprevalence was 90 percent, with seropositivity rates ranging from 75 percent to 100 percent in the different age groups and sexes. There was a significant difference between the antibody prevalences in Terra-Firme and Guamá 94 percent and 87 percent, respectively (P = 0.01). The geometric mean titres (GMT) of antibody to HHV6 declined from the first (>=2 years) to the sixth (31-40 years) age groups, and slightly increased (GMT %>50) among individuals older than 40 years.
