1Sanitation and Antiepidemic Station of Ning Xia Hui Autonomous Region.
Abstract:
An epidemiological investigation on pathogens of diarrhoeal diseases in Ning Xia was reported. Eight genus of agents were found in all stool specimens of persons with detectable rate of 41.16%. Moreover, the most prevalent pathogens were shigella (19.59%), followed by rotaviruses (10.07%), salmonella (4.76%), and entero-pathogenic Escherichia coli (4.20%). Four of them accounted for 93.85% of detectable agents. In addition, in shigella B group made up 80.44%, and 2a was the predominant agent. Similarly S. typhimurium accounted for 85.71% in salmonella. The detectable rates in different age groups ranged from 27.21% to 59.89%. It was was lower in the groups under one year and over fifty and highest (59.89%) in the groups aged 20-49. Regarding seasonal variation, the detectable rate fluctuated from 31.25-50.13%, and the highest prevalence was obtained in autumn, whereas the lowest in the winter. Besides, the most commonly found agent in any seasons was shigella. In spring and autumn rotavirus was more frequently found. This study revealed that there were no significant differences between male and female, Hui and Han people, or urban and rural areas in detectable rates of agents.
Insights
Diarrhoeal disease pathogens were investigated in Ning Xia, with shigella being the most common agent. Prevalence varied by age and season, with highest rates in adults during autumn.
Area of Science:
- Epidemiology
- Microbiology
- Public Health
Context:
- Diarrhoeal diseases pose a significant public health challenge globally.
- Understanding the etiological agents is crucial for effective disease control.
- Ning Xia, China, presents a specific epidemiological landscape for diarrhoeal pathogens.
Purpose:
- To conduct an epidemiological investigation of diarrhoeal disease pathogens in Ning Xia.
- To identify the prevalence and distribution of various infectious agents causing diarrhoea.
- To analyze demographic and seasonal variations in pathogen detection rates.
Summary:
- Eight genera of diarrhoeal pathogens were detected in 41.16% of stool specimens.
- Shigella (19.59%), rotaviruses (10.07%), Salmonella (4.76%), and enteropathogenic Escherichia coli (4.20%) were the most prevalent agents, accounting for 93.85% of detections.
- Prevalence peaked in adults aged 20-49 and during autumn, with shigella consistently being the most common pathogen across seasons.
Impact:
- This study provides critical data for targeted interventions and public health strategies in Ning Xia.
- Findings inform the development of diagnostic and treatment guidelines for diarrhoeal diseases.
- Highlights the importance of continued surveillance of diarrhoeal pathogens in diverse populations.
