Abstract

In order to assess the current seroepidemiology of hepatitis D virus (HDV) infection in Taiwan where hepatitis B virus (HBV) is hyperendemic, a total of 756 voluntary blood donors, 641 prostitutes, 1,014 patients with sexually transmitted diseases (STDs), and 628 drug abusers were studied. Radioimmunoassays were used for testing HBV infection markers and antibody against HDV (anti‐HDV) among HBsAg carriers. The anti‐HDV prevalence among HBsAg carriers was significantly higher in STD patients (9.6%), prostitutes (33.1%), and drug abusers (68.1%) than in blood donors from the general population (2.2%). The prevalence gradually increased with age in blood donors and STD patients, but reached a plateau at a young age in prostitutes and drug abusers. Males had a higher prevalence than females in blood donors (2.7% vs. 0), STD patients (8.2% vs. 7.5%), and drug abusers (69.0% vs. 57.1%), but the difference was not statistically significant. STD patients with syphilis had a higher prevalence (19.5%) than those affected with non‐ulcerating STDs (5.3%). While unlicensed prostitutes had a lower prevalence (1 3.6%) than licensed prostitutes (44.9%), intravenous drug abusers had a higher prevalence (73.1%) than non‐intravenous drug abusers (34.6%). There was a twofold increase in anti‐HDV prevalence from 1986 to 1989 among prostitutes, but the prevalence remained unchanged in the general population and drug abusers. HDV infection remains limited to the high‐risk groups and spread mainly by promiscuity and needle sharing in Taiwan. © 1992 Wiley‐Liss, Inc.
