Methods Antibodies against HEV (anti HEV) IgG and IgM were tested by enzyme linked immunosorbent assay (ELISA), and the risk factors of hepatitis E infection were investigated. Results Among 850 healthy subjects aged over 7 years old, the positive rates of anti HEV IgG and IgM were 46 35% and 3 06% respectively, the positive rates of anti HEV IgG in males and females, of which difference had statistical significance (P<0 001), were 53 62% and 39 54% respectively, and the positive rate of anti HEV IgM in females was higher than that in males (P<0 01). HEV infection lied in each age group, but the infection rates were not identical, and the difference had statistical significance (P<0 001), which increased with the age, but remained a stable level up to the group of 45～55 years old. Conclusions The infection rate of HEV in rural population of Deqing county is higher than that reported from other domestic districts. The study also shows that HEV infection is significantly associated with sex and age, males tends to suffer from HEV, and the infection rate increases with age, but remains a stable level up to a certain age.
