Background/Aims: Hepatitis A is an acute infectious disease transmitted by fecal-oral route. As the incidence of hepatitis A has been increased in Gwangju and Chonnam province of Korea recently, the number of hepatitis A patients in hospital employees has also increased. Thus, we investigated the seroprevalence of IgG anti-HAV in hospital employees below 40 years old.
Methods: We analysed the seroprevalence of anti-HAV IgG from 1,002 Chonnam national university hospital empolyees (men: 190, women: 812) who were below 40 years old. The age group was divided by 5 years; 21-25 years old 199 (19.9%), 26-30 years old 426 (42.5%), 31-35 years old 215 (21.5%), 36-40 years old 162 (16.1%).
Results: Overall seropositive rate of IgG anti-HAV was 32.8% (329/1,002). The seropositive rate of men was 40.5% (77/190) and that of women was 31.0% (252/812). The seropositive rates of each age group were 1.5% (3/199) in 21-25 years old, 21.6% (92/426) in 26-30 years old, 48.4% (104/215) in 31-35 years old, and 80.2% (130/162) in 36-40 years old. The seropositivity rate of the high risk group (doctors, nurses, technicians) was 28.9% (234/809).
Conclusions: The seropositive rate of IgG anti-HAV was the lowest in early twenties of hospital employees and below 50% in early thirties. Therefore, hepatitis A vaccination may be warranted in the hospital empolyees below the early thirties.
