To analyze the epidemiological and spatial-temporal aggregation characteristics of other infectious diarrhea (OID) in Hubei Province from 2013 to 2022, to provide scientific basis for disease prevention and control.

The data were collected from the infectious disease surveillance and reporting system of China Disease Prevention and Control Information system. Descriptive epidemiological methods, seasonal index analysis, and spatial autocorrelation analysis were used.

A total of 393 817 OID cases were reported in Hubei Province from 2013 to 2022. The reported annual incidence rate was 49.2/100 000 to 89.2/100 000. The overall incidence increased at first and then decreased. There were two peaks of incidence in winter and summer every year. The incidence rate showed a high-to-low trend from west to east, and the high incidence area changed dynamically with time, mainly in northwest and southwest regions. The sex ratio of reported cases ranged from 1.20 to 1.31, mainly in children under 5 years old (55.3%) and elderly people aged 60 and above(34.0%). The occupational categories were mainly children living at home (53.1%) and farmers (23.0%). Of the reported cases, 43 020(10.9%) were laboratory confirmed cases, of which viral diarrhea accounted for 95.4% and bacterial diarrhea accounted for 4.4%. The results of seasonal index analysis showed that there was a seasonal backshift in the epidemic month of viral diarrhea. The results of spatial autocorrelation analysis showed that the Moran I index was between 0.307 and 0.401, and there was spatial aggregation in each year. The number of “high-high” aggregation areas fluctuated and decreased, and the distribution was mainly in the northwest.

The incidence of OID in Hubei Province fluctuates, and there are obvious characteristics of temporal and spatial aggregation. Attention should be paid to the high incidence areas and key populations in the northwest, and the surveillance, prevention, and control of OID should be strengthened.
