Abstract: We report the results of seroepidemiological survey of Human immunodeficiency virus (HIV), Hepatitis B virus (HBV) and Hepatitis C virus (HCV) infections among the Karen, La-Wah and Lahu-Na, designated as the hill tribes, in northern Thailand. Some of these hill tribes are living in the remote and isolated mountain areas, settling their own communities. Anti-HIV seropositive cases were found only in the Lahu-Na (2.6%). The highest incidence of Hepatitis B surface antigen (HBs-Ag) positive was found in the Karen (13.2%), followed by the Lahu-Na (2.6%) and the La-Wah (1.7%). The highest incidence of anti-Hepatitis C virus antibody (anti-HCV) positive was found in the La-Wah (3.3%), followed by the Karen and the Lahu-Na (2.6%, respectively). Two out of nine anti-HCV positive cases were from seven and 11 year-old Karenean girls, who had no previous history of surgery, blood transfusion, intravenous medication, vaccination and dental therapy. These results suggest that HIV infections have not yet reached to the hill tribes, except the Lahu-Na. One of the possible transmission routes of HCV infection is a vertical or intrahhousehold infection among the hill tribes in northern Thailand.
