本文报告1984年8月份石家庄某铁路单位发生一例 EHF 病人,经 IFA 法检测 EHF抗体阳性而确诊。从患者工作环境检出带毒鼠。从而首次证实了石家庄铁路系统 EHF 疫源地存在,同时该病例也是石家庄市确诊首发病例。鼠分类:褐家鼠71.1%,小家鼠22.9%,大仑鼠4.8%,黑线姬鼠1.2%,带毒阳性鼠全部为褐家鼠。且全部捕自该患者工作的小卖部周围20米以内,提示患者可能吃了被鼠排泄物污染的食物或吸入污染的尘埃而感染。同时指出该疫点在1984年初的阶段尚属孤立的在特定条件上形成灶状疫点。提示带毒褐家鼠也可以通过货物等从远方输入,并在鼠密度高的环境内传播开来,为以后的城市型 EHF 流行酿成后患。提示车站货场及附近的单位要做好灭鼠工作,这对予防 EHF 传播有重要意义。
This article reports a case of an EHF patient in a railway unit in Shijiazhuang in August 1984 and was confirmed by IFA test for positive EHF antibody. Detected from the patient’s working environment with tetramine. Thus confirming for the first time the existence of the EHF epidemic in the railway system of Shijiazhuang and at the same time this case is also the first case of confirmed diagnosis in Shijiazhuang. Rat classification: Rattus norvegicus 71.1%, Mus musculus 22.9%, Durham 4.8%, Apodemus agrarius 1.2%, with poison-positive rats all Rattus norvegicus. And all were caught within 20 meters around the canteen where the patient was working, suggesting that the patient may have eaten food contaminated with rat excrement or inhaled contaminated dust. At the same time, it was pointed out that the epidemic point was still isolated in the early stage of 1984 and formed a foci-like epidemic on specific conditions. Prompted poisonous Rattus norvegicus can also be imported from afar through the goods, and spread in the environment of high density rats, resulting in the future of urban EHF epidemic. Prompt station yard and nearby units to do a good job of rodent control, which is important to prevent the spread of EHF.
