Seroepidemiology of HBV infection among health-care workers in South Sulawesi, Indonesia.

Exposure to HBV showed significant association with HCWs' age, work type, and service period. Needlestick injury was the highest risk factor for the acquisition of HBV, with highest events in the intervention work-type. Two thirds of HCWs were still susceptible to HBV infection.
