ABSTRACT
Objective To analyze the burden of intestinal infectious diseases in Jining city from 2009 to 2016, determine the epidemic trends and the high-risk groups in this area, so as to provide evidence for the prevention and control of intestinal infectious diseases. Methods The intestinal infectious diseases case information were collected from the Infectious Diseases Surveillance Information Reporting System. Based on these data, the incidence rate, the years lived with disability (YLDs) and the intensity of YLDs of intestinal infectious diseases was calculated. Results From 2009 to 2016, the annual incidence rate of intestinal infectious diseases in Jining city was 128.81/100 000, the annual incidence rate of subtype diseases in the descending order were other infectious diarrhea (74.74/100 000), hand-foot-and-mouth disease (49.15/100 000), bacillary dysentery (3.65/100 000), hepatitis E (0.57/100 000), acute hemorrhagic conjunctivitis (0.37/100 000) and hepatitis A (0.34/100 000). The highest incidence of intestinal infectious diseases was at May to August. The total YLDs caused by intestinal infectious diseases were 593.04 person-years, including 372.31 person-years for males and 220.73 person-years for females. The YLDs ranked in descending order were of hand-foot-mouth disease (326.88 person-years), other infectious diarrhea (235.74 person-years), hepatitis E (10.65 person-years), bacillary dysentery (10.09 person-years), hepatitis A (7.71 person-years), and acute hemorrhagic conjunctivitis (1.97 person-years), and the corresponding intensity of YLDs were 0.489, 0.353, 0.016, 0.015, 0.012, and 0.003 person-years /100 000, respectively. Conclusions The hand-foot-and-mouth disease and the other infectious diarrhea were the main intestinal infectious diseases subtypes prevailed in Jining city from 2009 to 2016, whose incidence was highest in the season of summer, and the preschool children and elderly people were the high-risk populations. According to its incidence characteristic, relevant government departments can take effective measures to prevent and control the intestinal infectious diseases in Jining city.
