The worldwide distribution of the HBV infection has usually been estimated by the prevalence of hepatitis B surface antigen (HBsAg) among the general population. Total antibodies for hepatitis B core antigen (anti-HBc) are the most important diagnostic marker for proving prior exposure to HBV.
Aim
The aim of this study was to determine the prevalence of Hepatitis B virus (HBV) infection among Bulgarian population. Reliable epidemiologic data is needed to estimate the prevalence of Hepatitis B in order to determine the actual burden of the infection and to plan prevention and control measures.
Materials and methods
A total of 2140 serum samples were tested for major serological markers of HBV (HBsAg and anti-HBc) for a period of two years (2018-2019).
Results
We established an intermediate prevalence of HBsAg (5.1%) and high prevalence of anti-HBc (27%) among HBsAg negative individuals.
Conclusion
In conclusion, the prevalence of Hepatitis B is much higher among those born before the introduction of universal hepatitis B vaccination in Bulgaria (1992).
