Epidemic Characteristics, Spatial-Temporal Pattern, and Risk Factors of Other Infectious Diarrhea in Fujian Province From 2005 to 2021: Retrospective Analysis
ABSTRACT
Background:
Other infectious diarrhea (OID) remains a serious public health threat to all age groups in Fujian Province.
Objective:
This study explores the links between demographic, social, and environmental factors and OID in Fujian from 2005 to 2021, as well as the epidemic characteristics and spatial-temporal pattern.
Methods:
Incidence data for OID from 2005 to 2021 in Fujian were extracted from the China Information System for Diseases Control and Prevention. Moran's Index and Kulldorff’s scan statistics were performed to explore the space-time pattern of OID, and geographical weighted regression was used to determine possible risk factors.
Results:
The average annual incidence of OID was 60.3 per 100,000 population, and children under two years counted for 50.7% (196,905/388,636) of all cases. From 2005 to 2017, there was a steadily increasing OID trend from 2005 to 2017; and a clear seasonal shift from autumn to winter/spring. The spatial and temporal aggregations were concentrated in Zhangzhou City and Xiamen City for 17 study years. Factors like populated areas with a large under-one-year population, less economically developed areas, and higher pollution levels contributed to OID cases in Fujian Province.
Conclusions:
We investigated the epidemiological characteristics, spatial-temporal pattern, and risk factors of OID in Fujian Province. Disease-specific and location-specific interventions might be possible based on the findings.
