近几年,我省襄阳、孝感、随州、鄂州、钟祥及蕲春等县、市中学生相继发生一种由毒隐翅虫叮咬所致的皮炎。病变主要发生在人体暴露部位。为了解其发病规律,便于制定防治措施,我们于1987年对蕲春县一中进行了调查。现将结果报告如下: 蕲春县一中位于县郊区,建有四层楼教室。学校周围为大面积某地及污水沟,校园内低洼潮湿,杂草及多年堆积的垃圾未予清除。 1 发病率:二至四楼为高中二、三年级的749名学生,1987年共发病380人(发病率50.73％)。发病率随楼层增高而升高,二楼4.50％(15/333),三楼77.74％(220/283),四楼99.25％(132/133)。
In recent years, Xiangyang, Xiaogan, Suizhou, Ezhou, Zhongxiang and Hunchun counties and city middle school students in our province have successively developed dermatitis caused by venomous flies. Lesions occur mainly in human exposure sites. In order to understand its incidence and facilitate the development of prevention and control measures, we conducted a survey in 1987 in Hunchun County. Now report the results as follows: Hunchun County, located in the outskirts of the county, built four-story classrooms. A large area around the school and a sewage ditch, low-lying wet campus, weeds and garbage accumulated for many years not cleared. 1 Incidence: From the second to the fourth floor, there are 749 students in the second and third grades of senior high school. In 1987, a total of 380 people were found (incidence 50.73%). Incidence increased with floor height, 4.50% (15/333) on the second floor, 77.74% (220/283) on the third floor and 99.25% (132/133) on the fourth floor.
