Abstract: Objective To investigate the source, transmission route and risk factors of an outbreak of severe fever with thrombocytopenia syndrome (SFTS), and provide a scientific basis for prevention and control. Methods To investigate the cases'epidemiological history, exposure history, domesticated animals infection status and biological disease vectors. The real-time PCR and double antigen sandwich test were applied for pathogen detection Results Four clustered outbreaks which occurred in rural areas involved two in Penglai city, one in Haiyang city and Qixia city from 2013 to 2016. These clustered outbreak involved 17 cases. There were 11 male and 6 female cases. Four cluster outbreak reason was divided into two kinds. One was direct contact with confirmed cases and another was exposed to the suspicious external environment. Conclusion Medical staff need training for hospital infection control and strengthened health education. Family members should strengthen the personal protection and avoid contacting with the patient's blood or secretions. The human body of death case needs to be processed properly. The close follow up should be carried out, environmental management and tick control should be implemented as needed.
