肺炎的发病率在上升,曾报道居民年发病率为0.3％。肺炎也是住院患者的常见病因,占10％。但对社会获得性肺炎来说,该数值不够准确,因为只有50％患者需要住院,其余可自愈。存在的问题是诊断较困难,而且由于新病原体的发现和先进技术的应用,使肺炎的病原学研究发生了变化。为了获得准确的病原学诊断,以非损伤性方法研究了165例有肺炎 The incidence of pneumonia is on the rise, with a reported annual incidence of 0.3%. Pneumonia is also a common cause of hospitalized patients, accounting for 10%. However, for social-acquired pneumonia, the value is not accurate enough, as only 50% of patients require hospitalization and the rest can be self-healing. The problem is that it is more difficult to diagnose and because of the discovery of new pathogens and the application of advanced technologies, the etiology of pneumonia has changed. In order to obtain accurate etiological diagnosis, non-invasive methods were studied in 165 patients with pneumonia
