一、初步判断:根据了解的情况,对这次“不明高热”的流行,初步分析如下。 (一)患者在发病前均有在草滩施工和接触滩水的历史,而未去滩地施工者无一发病。停止施工和接触滩水后,无续发病例。提示这次的流行病,很可能是经皮传染病。 (二)在当地已知的经皮传染病有四种:血吸虫病、钩端螺旋体病、钩虫病及动物血吸虫尾蚴皮炎。根据当地是血吸虫病流行区,部队施工时间正是流行季节,患者接触滩水后多有皮炎发生,一个月左右出现高热、荨麻疹、腹泻、肝脾肿大、白细胞总数及嗜酸
First, the initial judgment: According to the understanding of the situation, the prevalence of this “unknown high fever,” a preliminary analysis is as follows.
