  1. High prevalence in Central Africa of blood donors who are potentially infectious for human herpesvirus 8.

    Article - En anglais


    In western countries, the transmission of human herpesvirus 8 (HHV-8) via blood transfusion has been recently postulated.

    In sub-Saharan African, the incidence of HHV-8-associated Kaposi's sarcoma and the seroprevalence for HHV-8 in autochthonous populations are high.


    The aim of this study was to estimate the prevalence of blood donations potentially infectious for HHV-8 in the general adult population of Central Africa.

    Forty-nine blood donors at the Centre de Transfusion Sanguine in Bangui, the capital of the Central African Republic, were selected.

    Forty-five inpatients of Broussais Hospital, Paris, France, who were known to be seronegative for HIV and hepatitis B and C viruses and who had not received heart or kidney transplants, were chosen as a European « control » group for comparison.

    HHV-8 DNA sequences were detected in peripheral blood mononuclear cells by nested polymerase chain reaction using primer sets located in the HHV-8 open reading frame 26.


    Eleven (22.5% ; 95% Cl : 12% - 37%) of 49 blood donors were positive for HHV-8.

    Three (6%) were HIV-1 seropositive.

    Two (67%) of the 3 HIV-infected blood donors were also positive for HHV-8.

    All blood donors were apparently healthy ; none was known to suffer from Kaposi's sarcoma.

    Only one (2.2%) control was carrying HHV-8 DNA on the peripheral blood mononuclear cells. (...)
