Distribution of HIV and Acute Hepatitis B Infection among Drug Injectors in Glasgow

This study compared the distributions of known human immunodeficiency virus (HIV) and acute hepatitis B virus (HBV) infection among drug injectors in Glasgow over a 3.5 year period. Data were obtained from all relevant laboratory request forms submitted to Glasgow's 3 virology laboratories during the period 1 January 1986 to 30 June 1989. The overall prevalence of HIV among those tested was 3.7% (66/1786). There were 125 cases of acute HBV infection. The male:female ratios for HIV and acute HBV were 1:1 and 2:1, respectively. Thirty-four per cent of persons with HIV were aged under 21 years compared with 53% with acute HBV. Three out of 10 areas of the city accounted for 92% of HIV infection but only 66% of acute HBV infection. HIV infection was not detected among drug injectors in 4 areas of the city but at least 2 cases of acute HBV infection were recorded in all 10 areas. The geographical and age distribution of acute HBV infection in Glasgow suggests that the potential for future spread of HIV among drug injectors remains considerable.
