作者以日本的流行病学及临床为中心,综述报告了肺炎支原体感染症。一、流行病学:支原体在适宜的湿度下能长期存活,故可经空气飞沫传染。在人群密切接触的生活环境易发生流行。据报告,家族中如有一名患者,其家族成员小儿的84%、成人的41%可被传染发病。潜伏期平均为3周,除少数散发发病外均有多发的流行年,约每四年出现一流行高峰,其流行特点是在一年内外持续地缓慢流行,以7～11月份发病最多。防止本症发病的有效抗体是代谢抑制抗体,据测定结果表明,人群中各年度的该抗体水平无显著差异,故认为每四年一次流行与抗体以外的未知因素有关。其 The author of Japan epidemiology and clinical as the center, a review report of Mycoplasma pneumoniae infection. First, the epidemiology: Mycoplasma long-term survival in the appropriate humidity, it can be infected by air droplets. Living in close contact with the crowd prone to epidemic. It is reported that if there is one patient in the family, 84% of pediatric members of their family members and 41% of adults may be infected. The average incubation period was 3 weeks. Except for a few cases of epidemic occurrence, there were many popular epidemic years and about one peak occurred every four years. The epidemic characteristic was that it continued to slow epidemically within a year and beyond, with the highest incidence in July and November. The effective antibody to prevent the onset of this disease is metabolic inhibition of antibodies, according to the results showed that the population of the antibody levels in each year was no significant difference, it is considered once every four years, the prevalence of unknown factors other than antibodies. its
