Abstract:
Objective:This study analyzed the epidemiological characteristics of the clustered cases of severe fever with thrombocytopenia syndrome (SFTS) in Jiangsu province, so as to provide a scientific basis for prevention and control efforts.Methods:In this study we searched for cases related to clustered outbreaks and conducted epidemiological investigations of the cases, their co-exposed individuals, and close contacts. The basic information of the cases and their disease progression were collected and documented. The source of infection and transmission routes were analyzed. Fisher’s exact probability test and independent samples t-test were used to compare the differences between index and secondary cases. Results:From 2018 and 2024, a total of nine cluster outbreaks were reported in Jiangsu province, involving 32 cases of SFTS with 12 fatalities. Seven clustered outbreaks occurred in rural communities, while two occurred in medical institutions. The primary cause of these outbreaks was direct contact with confirmed cases.Conclusions:In recent years, Jiangsu province has experienced multiple clustered outbreaks of SFTS. Targeted health education should be implemented in high-risk areas to increase awareness of personal protective measures. Medical institutions should standardize the management of confirmed cases, educate patients′ families about prevention and control measures, and strengthen training for healthcare workers to ensure effective infection control within hospitals.
