社区获得性肺炎(community-acquired pneumonia)是一个严重的卫生问题,目前仍是最常见的致死性社区获得性感染。应用抗生素后,虽然肺炎球菌性肺炎的病死率降低了近60％,但住院病人的病死率仍有10～20％,而该病死率有可能获得进一步降低。最近英国胸部疾病学会进行了一项研究,使用致病菌敏感的抗生素快速治疗,没有死亡病例发生。肺炎的病原学诊断较为困难。一般来 Community-acquired pneumonia is a serious health problem and is by far the most common fatal, community-acquired infection. Although the mortality rate of pneumococcal pneumonia is reduced by nearly 60% after antibiotics are administered, in-patient mortality is still 10-20% and the mortality rate is likely to be further reduced. A recent study by the British Society of Chest Diseases conducted rapid treatment with a pathogen-sensitive antibiotic and no deaths occurred. Etiological diagnosis of pneumonia is more difficult.
