Objective] To understand the current status of HBV infection among employees of public places in ShunYi district of Beijing City during 2006 to 2008, and analyze the existed problem. Methods] The Enzyme-linked Immunosorbent Assay （ELISA） was applied to detect serum hepatitis B markers among employees of public places .

The HBsAg positive rate among male（ 1.68%） was higher than that among female（ 1.18% ） , the difference was significant （ Χ^2 = 67.69, P 〈 0.01 ） ; the maximum of HBsAg positive rate was in under 20-year-old age group （ 1.83% ） ; the minimum was in above 50-year-old age group （0.92% ）. The HBsAg positive rate of employees in food industry （ 1.30% ） was lower than that of employees in public places （ 2.40% ）, the difference was significant（Χ^2 = 115.54, P 〈 0. 01 ） ; the HBsAg positive rate of local population （ 0.62% ） was lower than that of the immigrant（ 1.63% ） , the difference was significant.
