Seroprevalence of Hepatitis B in blood donors from Maracaibo Zulia. Period 2000-2005
Hepatitis B is a serious disease caused by aDNAvirus that attacks the liver. The infection may either be acute or chronic. Hepatitis B is transmitted through exposure to bodily fluids containing the virus. This includes unprotected sexual contact, blood transfusions, re-use of contaminated needles a...

A total of 1.439 (3.09%) cases were seropositive for Anti-HBc, which corresponds to the real seroprevalence, since the marker found in this group indicates past infections. 97 (0.208%) sera where found to be positive for HBs-Ag, indicating incidence or new cases. However, 95 (0.205%) sera had both HBs-Ag and Anti-HBc positive, which means that both markers were present in each of these 95 donors and this could be a motive for the development of acute or chronic diseases. 95.16% of the positive sera where taken from male patients and the larger prevalence (32.42%) is between the ages of 29 through 39 years old.
