[Advances in epidemiology, etiology, and treatment of community-acquired pneumonia].

Community-acquired pneumonia (CAP) is the third leading cause of death worldwide and one of the most commonly infectious diseases. Its epidemiological characteristics vary with host and immune status, and corresponding pathogen spectrums migrate over time and space distribution. Meanwhile, with the outbreak of COVID-19, some unconventional treatment strategies are on the rise. This article reviewed the epidemiological characteristics, pathogen spectrum and treatment direction of CAP in China over the years, and aimed to provide guidance for the diagnosis and treatment of CAP in clinical practice.社区获得性肺炎（CAP）是全球第三大致死原因，是最常见的感染性疾病之一。其流行病学特征因宿主和免疫状况而异，病原谱也随时间和空间分布而迁移；与此同时，随新冠疫情突发，一些非传统治疗策略正在兴起。本文对我国近年来CAP的流行病学特征、病原谱变迁及治疗方向转变进行阐述，以期为CAP的诊疗提供参考。.
