title: Seroprevalence of HHV 8 antibodies among the general population and HIV positive persons in the Czech Republic.
abstract: BACKGROUND
  The seroprevalence rates of herpesvirus 8 (HHV 8) antibodies were determined for the general Czech population and HIV-positive individuals.
  
  
  OBJECTIVE
  Six hundred and sixty six serum samples from the general Czech population and 129 serum samples from HIV-positive persons were tested for the presence of antibodies to the HHV 8 lytic and latent antigens.
  
  
  METHODS
  HHV 8 antibodies were detected by the indirect immunofluorescence test.
  
  
  RESULTS
  In the general Czech population, only 2.4 and 0.3% of the serum samples tested positive for antibodies against the lytic and latent HHV 8 antigens, respectively. As many as 34.9 and 10.9% HIV positive individuals had antibodies to the HHV 8 antigens, respectively. Only three of them have developed Kaposi's sarcoma (KS) to date. At the time of KS diagnosis, the three patients had antibodies to both HHV 8 antigens. HIV-positive homo/bisexuals were at significantly higher risk of acquiring HHV 8 infection compared with HIV-positive heterosexuals. The increase in HHV 8 seroprevalence was associated with progression of the HIV infection from stage A to stage B. No correlation was found between the HHV 8 seroprevalence and CD 4+T-lymphocytes counts or the HIV viral load.
  
  
  CONCLUSIONS
  Among the general Czech population, the HHV 8 seroprevalence is as low as in the West European countries. The mean HHV 8 seroprevalence rate in HIV-positive individuals was 34.9% and was comparable with those reported in other low seroprevalence countries.
