Summary:Hepatitis B virus markers and antibodies to delta agent were studied in adult people (15-54 years) in the province of Haut-Ogooue (Gabon), randomly selected by cluster sampling technique. Of the 384 people, 37 (9.6%) were positive for HBsAg, of which 23 (62.2%) were positive for HBeAg; 246 (65.3%) had anti-HBs and 53 (13.8%) had anti-HBc as the only marker. Chronic carriage of HBV defined as presence of HBsAg or exclusive anti-HBc was observed in 90 people (32%). At least one of the HBV markers was found in 89% of the people. Women were more frequently positive than men. No difference in relation to age was observed. Anti-delta was found in 12 (3.5%) of the 341 people with HBV markers and 7/12 of these could be considered as chronic HBV carriers.
