[Antibody detection of hepatitis E virus in human population of different national in China].
OBJECTIVE
To investigate the seroprevalence of HEV infection in different national human population in Han, Hui and Zang in China.


METHODS
EIA was used for detecting anti-HEV IgG of the serum samples. All samples were collected in 2006-2008 in Sichuan, Beijing, Heilongjianin, Sandong, Gansuo, Ningxia and Qinghai areas.


RESULTS
The total positive rate of anti-HEV IgG was 17.97% (1878/ 10448), 24.32% (1794/7376) in Han national, 3.59% (81/2258) of Hui national and 0.37% (3/814) of Zang national, respectively. The positive rate of Han human at different age group, was 5.19% of < or = 10 year, 11.64% of 11-20 year, 20.08% of 21-30 year, 34.17% of 31-40 year, 41.75% of 41-50 year, 48.58% of 51-60 year, 57.43% of > or = 61 year. The positive rate of Hui human at different age group, was 3.11%, 3.96%, 2.11%, 3.98, 2.52%, 4.57% and 6.67%, respectively. Three positive of Zang human was between 21-60 year.


CONCLUSIONS
The HEV infection in Han national population was higher than the Hui and Zang national, significantly. The HEV infection was correlation with age significantly, the infection rate was increased with age.
