BACKGROUND: Human herpesvirus 8 (HHV-8) is associated with Kaposi's sarcoma. In the US and Europe, HHV-8 is believed to be mainly sexually transmitted, but reports from some African countries suggest non-sexual transmission. OBJECTIVES: To find out more about HHV-8 seroprevalence and transmission in Eastern Africa. STUDY DESIGN: In this study, 411 serum samples from different population groups in Eritrea (children, pregnant women, female sex workers and members of the isolated Rashaida tribe) were examined for HHV-8 antibodies with an immunofluorescence assay detecting antibodies to latent and lytic HHV-8 antigens. RESULTS: Antibodies to HHV-8 latent antigen were found in 0-2% of Eritrean children, 5% of pregnant women, 8% of female sex workers and 26% of Rashaidas, respectively. No correlation was found between detectable HHV-8 antibodies and seropositivity to HIV or herpes simplex 2. CONCLUSIONS: These results suggest that HHV-8 infection is relatively common in Eritrea and that viral transmission occurs predominantly through non-sexual route in this region.
