一、绪言溶血性链球菌(以下简称链球菌)感染和其他急性上呼吸道感染一样,是集体单位发病率较高的传染病,如扁桃腺炎、咽峡炎、猩红热等,在临床上经常碰到。因此,其发病因素以及细菌对周围环境的污染情况等,在流行病学上具有一定的意义,是值得研讨的问题。有鉴于此,我们组织了一个调查研究小组,在某学院内对链球菌感染的发病率及其流行病学进行了调查研究。工作的重点是以预防为主。为了控制流行的发生与蔓延,在平时及流行季节里实施了一系列的综合性防治措施,包括流行病学调查、实验室诊断与临床工作等。现总结报告如下。二、调查方法(一)对象主要调查研究对象为全体学员。学员年龄介于20 First, the introduction Hemolytic streptococcus (hereinafter referred to as streptococcus) infection and other acute upper respiratory tract infection, the collective unit is a higher incidence of infectious diseases, such as tonsillitis, angina, scarlet fever, clinically often touch To Therefore, its pathogenesis and bacterial contamination of the surrounding environment, etc., has a certain epidemiological significance, is worth discussing. In view of this, we organized a research team to investigate the prevalence and epidemiology of streptococcal infections in a college. The focus of the work is prevention. In order to control the occurrence and spread of the epidemic, a series of comprehensive prevention and control measures have been implemented in usual and popular seasons, including epidemiological investigation, laboratory diagnosis and clinical work. The report is summarized as follows. Second, the survey method (a) the main object of the survey for all participants. Students are between 20 years old
