We report on a viral hepatitis serosurvey done on 381 nursing students in Bangkok; 360 (94%) were female. The mean age was 20 (+/-3.6) years (range 16-41 years); 143, 92, 86 and 59 students came from Thailand's Central, North, Northeast and South provinces, respectively. The overall prevalence of hepatitis A, B, C and E antibody in the students was 8.9%, 10.8%, 0.5% and 11.5%, respectively. The highest seroprevalence to hepatitis A was observed in cadets from the southern region of Thailand. Seroprevalence rates to hepatitis A and B were less than in other reported studies in Thailand.
