老年人病毒性肺炎鉴别诊断

2019年12月武汉报道多起新型冠状病毒肺炎。引起该疾病的病毒是单股正链RNA病毒,具有较强传染性,可感染多种动物和人。其临床特征与严重急性呼吸综合征(SARS)、A/H5N1禽流感、腺病毒肺炎及甲型H1N1流感等病毒性肺炎类似,不易鉴别。本文综述了上述病毒性肺炎的流行病学、临床表现、实验室及影像学检查方面的共性与特异性,对临床病例诊断及鉴别有一定指导作用。

Differential diagnosis of viral pneumonia in the elderly

In December 2019, dozen of cases of respiratory illness caused by a novel coronavirus were reported in Wuhan, Hubei Province, China. The identified virus, named as 2019 novel coronavirus (2019-nCoV), is single-stranded positive sense RNA, and can infect a variety of animals and people because of its strong infectivity. The clinical features of the novel coronavirus-infected pneumonia are similar to those of severe acute respiratory syndrome (SARS), A/H5N1 avian influenza adenovirus pneumonia, and A H1N1 influenza, and thus, the disease is not easy to be distinguished. In this paper, we review the commonalities and specificities in epidemiology, clinical manifestations, laboratory results and radiological features among above mentioned viral pneumonia, and hope to provide guidance to the diagnosis and differential diagnosis of clinical cases.
