Abstract:

Objective To investigate the characteristics of other infectious diarrhea in Weifang City for evidence to optimize the prevention and control measures. Method The cases of other infectious diarrhea reported in Weifang area in the Chinese Disease Prevention and Control Information System were cumulatively collected from 2017 to 2021, and analyzed using descriptive epidemiology for the distribution characteristics of other infectious diarrhea in different region, population and time in Weifang. Results A total of 43 089 cases of other infectious diarrhea were reported in Weifang from 2017 to 2021, with an average 8 618 cases annually reported, and no deaths occurred. Average annual incidence was 92.01/100 000. The distribution of reported cases had a certain seasonal, with two peaks in July and December. Counties (cities and districts) with the largest number of cases reported were Kuiwen District (n=1 428), Linqu County (n=993), Zhucheng City (n=914) and Shouguang City (n=903). The annual number of reported cases and incidence in males were 4 765 and 99.62/100 000, and those in females were 3 853 cases and 84.07/100 000, both of which were higher in males than in females. Children aged 0 to 3 years had the highest number of reported cases and incidence. By occupation, the proportion was relatively higher in scattered children (3 786 cases, 43.93%) and farmers (2 927 cases, 33.96%). Rotavirus was mostly detected in children aged from 0 to 9 years, which accounted for 88.53% (1 705/1 926), yet rotavirus and norovirus were more seen in those over 10 years old, which accounted for 42.24% (98/218) and 34.48% (80/218), respectively. Rotavirus showed certain seasonal characteristics, while other viruses did not show obvious seasonal trend. Conclusion Incidence of other infectious diarrhea in Weifang had obvious seasonal characteristics. The findings suggest that scattered children and farmers should be the important population for prevention and control of the infection.
