METHODS： Blood samples from 410 unselected schoolboys, 666 students, 500 military personnel, 1286 casual blood donors, 378 voluntary blood donors and 640 pregnant women （total 3880 non-vaccinated residents of rural and metropolitan areas from all over Albania; 2354 （60.7%） male and 1526 （39.3%） female; mean age of 26.3 years） were tested during 2004-2006 for hepatitis B surface antigen （HBsAg） and antibodies to hepatitis B virus （anti-HBs） by ELISA. RESULTS： The HBsAg and anti-HBs prevalence were 9.5% and 28.7%, respectively. The highest HI3sAg prevalence was evident in the younger age group, such as in schoolchildren （11.8%） and the military （10.6%）. Consequently, the anti-HBs prevalence increased with age, from 21.2% in schoolchildren （mean age： 15.7 years）, to 36.3% in pregnant women （mean age： 26.3 years） and 29.7% in voluntary blood donors （mean age： 40.1 years）. There were no significant differences between males and females. CONCLUSION： Despite the estimated two-fold reduction of HBsAg prevalence in the general population from about 18%-19% to 9.5%, Albania remains a highly endemic country （i.e. over 8% of HBsAg prevalence rate）.展开更多
