Abstract:
Objective To investigate the epidemiological characteristics of severe fever with thrombocytopenia syndrome (SFTS) in Weihai, Shandong province and analyze the influencing factors of Bunyavirus infection, and to provide theoretical basis for the prevention and treatment of SFTS. Methods A total of 143 PATIENTS with SFTS in Weihai area of Shandong Province from March 2016 to March 2021 were selected from The China Disease Control and Prevention Information System, and another 215 healthy people in Weihai area of Shandong province during the same period were selected as the control group. 5ml of fasting elbow venous blood was collected from all subjects. Our hospital used daan biological fever with thrombocytopenia new Bunia virus PCR kit detection; All subjects were investigated by unified questionnaire and questioned by trained investigators, including age, sex, pet keeping, poultry breeding, bitten by ticks one month before the disease, engaged in field work, had ticks around their living areas, and had weeds and shrubs around their homes and working areas. Logistic regression was used to analyze the independent risk factors of new Bunia virus infection in SFTS patients. Results A total of 143 cases of SFTS were mainly distributed in Rongcheng city (33.57%) and Rushan City (28.67%). The incidence of SFTS mainly occurred in spring (45.45%), and the occupational distribution was mainly farmers (89.51%). All 358 SFTS patients were positive for new Bunia virus by PCR. Univariate analysis showed that there were statistically significant differences between the two groups in exposure to pet raising, poultry farming, tick bite 1 month before the disease, ticks around the living area, working in the field, working area and weeds and shrubs around the house (P<0.05). logistic regression analysis showed that poultry farming, field operation and ticks around living quarters were independent risk factors for SFTS infection in Weihai, Shandong province ( P<0.05). Conclusions SFTS patients in the majority with flourish in shandong weihai region, mainly concentrated in summer and autumn, for the effective prevention and control of new cloth to SFTS virus infection occurs, should do a good job in disease surveillance in the field operation completes the protection measures, reduce the poultry production, spraying kill ticks around the living area, focus on strengthening the residents' awareness of occupational protection.
