摘　　要：目的为弄清海训部队发生群体性皮炎情况，并做好防治。方法在现场采用个案随机调查及走访当地防疫部门，查阅相关文献，逐一分析并采取防治措施。结果发现海训部队开训近一周后就发生皮炎，随机调查64名官兵，出疹率为96．9％（62／64）。尤以双下肢暴露部位皮肤出现红点、丘疹、水疱样皮疹；其原因为蚋类昆虫叮咬引起。因海训场存在成群结队的蚋类昆虫，从早上6：00一直到黄昏都有叮咬活动，其活动高峰为上午7：00—9：00时，平均密度为28只／人工小时；下午4：00～6：00，平均密度为56只／人工小时。经现场处理后蚋密度下降，皮疹病人逐渐减少，说明防治有效。结论蚋类昆虫引起群体性皮炎应引起重视。Objective In order to make clear for factors of biting dermatitis and carry on control of dermatitis in officers and soldiers of army unit in training-sea.
