ResultsA total of 25 487 cases of 6 intestinal infectious diseases were reported during this period with the average annual incidence rate of 53.87/lakh, accounting for 29.74% of total notifiable infectious diseases cases. The incidence rate declined from 72.79/lakh in 2001 to 25.88/lakh in 2008, and the declines of the incidence of hepatitis A and dysentery were obvious.
