Background: Currently, the incidence of hepatitis A is on the increase in Korea. Although there is emphasis on contact precautions, the nosocomial outbreak of hepatitis A virus (HAV) in healthcare personnel has increased within endemic areas because these workers inevitably come in close contact with patients and work under suboptimal hygiene conditions. In this study, we evaluated the necessity of immunization against HAV for healthcare personnel.
Methods: We investigated the seropositivity of serum immunoglobulin G (IgG) anti-HAV antibody (Ab) in 672 healthcare personnel on the basis of their age-group, sex, and occupation in Soon Chun Hyang University Hospital and Soon Chun Hyang University Bucheon Hospital.
Results: The subjects were divided into 6 groups on the basis of their ages to identify differences among the various age groups in the number of cases with HAV Ab seropositivity. Significant intergroup differences were noted in this respect: 21-25 years, 2/152 (1.3%); 26-30 years, 33/245 (13.5%); 31-35 years, 70/148 (47.3%); 36-40 years, 52/79 (65.8%); >40 years, 44/48 (91.7%).
Conclusion: The number of seropositive cases was low among young healthy personnel: low seropositivity is an emerging risk for vulnerable population. With the increase in the incidence of hepatitis A, healthcare personnel have become a risk population for hepatitis A, as are community residents. Therefore, for healthcare personnel working in hospitals, immunization against HAV should be recommended for personnel younger than 30 years, and serological testing for older personnel.
