The positive rate of HAV-IgM in different age groups decreased with the increase of age, and the differences of HAV-IgM positive rate among different age groups were statistically significant （χ2=49.080, P=0.000）. The HAV positive rate of managers and food processing enterprises was lower than that of other professions （χ2=65.557, P=0.000）.
