Journal of the Association of Physicians of India. 1989 Feb; 37(2): 160-1http://imsear.searo.who.int/handle/123456789/95524A survey of Hepatitis B virus (HBV) carrier state of paid and voluntary blood donors in and around the city of Calcutta has been carried out. HBV carrier state is higher in paid donors (5.84%) than voluntary donors (1.79%). The nutritional status of paid donors as assessed by serum protein, immunoglobulin and cholesterol shows evidence of malnutrition and chronic infection. The socio-economic status of the prospective blood donors has an important bearing on the persistence of carrier state for HBV.engAdolescentAdultBlood DonorsCarrier StateHepatitis B --epidemiologyHumansIndiaMiddle AgedComparative Study
