目的调查一起发热伴血小板减少综合征疫情的流行特征。方法通过新型布尼亚病毒感染病例的监测和鉴定、临床症状和流行病学调查、媒介生物的病原携带研究,分析一起发热伴血小板减少综合征疫情的临床表现和流行特征。结果岱山县发现1例75岁女性患者,2013年7月18日发病,23日收住入院,出现腹泻(清水样),淋巴结肿大,伴血白细胞、血小板呈进行性下降,发病7天后死亡。其丈夫于7月21日发病。经RT-PCR核酸检测报告2例病例新型布尼亚病毒核酸均阳性。媒介生物病原检测,布尼亚病毒核酸未发现阳性。结论该起疫情2例病例存在共同暴露发病的可能;但由于居住条件的相对局促,也不能排除生活密切接触传播的可能。
Objective To investigate the prevalence of fever with thrombocytopenia syndrome. Methods The clinical manifestations and epidemiological characteristics of fever with thrombocytopenia syndrome were analyzed through monitoring and identification of new cases of Bunyan virus infection, clinical symptoms and epidemiological investigation, pathogenic carriage of vector organisms. Results A 75-year-old female patient was found in Daishan County. On July 18, 2013, the patient was admitted to Daishan County and admitted to hospital on the 23rd. He was admitted with diarrhea (clear water sample), swollen lymph nodes, white blood cells accompanied by leukopenia and thrombocytopenia. . Her husband was on July 21. Two cases of new Bunyavirus nucleic acid were detected by RT-PCR. Vector bioassay, Bunyavirus nucleic acid was not found positive. Conclusion The two cases of outbreak may have the possibility of co-exposure. However, due to the relatively cramped living conditions, the possibility of close contact with life can not be ruled out.
