| 1 | Epidemiology of hepatitis B virus infection in Albania显示文摘AIM:To assess the prevalence and socio-demographic distribution of hepatitis B virus(HBV) infection in Albania.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 HBsAg 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). | Bashkim Resuli Skerdi Prifti Bledar Kraja Tatjana Nurka Mimoza Basho Edita Sadiku | 2009 | World Journal of Gastroenterology2009，15，7： | 9 |
