[Antibody detection of hepatitis E virus in some human population, swine and chicken in Beijing in China].

Objective: To investigate the seroprevalence of HEV infection in human population, swine and chicken in Beijing region.

Methods: EIA was used for detecting anti-HEV IgG of the serum samples. All samples were collected in 2006-2007 in Beijing areas.

Results: The anti-HEV IgG was detected positive in 21.52% of human (260/1208), 46.88 % (15/32) of swine, but was negative in chickens (0/24). The positive rate of human at different age group, was 5.60% (14/250) of 11-20 year, 20% (42/210) of 21-30 year, 24.03% (62/258) of 31-40 year, 26.44% (78/295) of 41-50 year, 32.82% (64/195) of 51-60 year. The male (29.51%) was higher than the female (21.70%).

Conclusion: The HEV infection was correlation with age and sex significantly. The infection rate was increased with age, the positive rate in swine was more double than the human population.
