2019 Novel Coronavirus—Important Information for Clinicians

In early December 2019 a patient was diagnosed with an unusual pneumonia in the city of Wuhan, China. By December 31 the World Health Organization (WHO) regional office in Beijing had received notification of a cluster of patients with pneumonia of unknown cause from the same city.¹ Wuhan, the capital city of Hubei Province in central China, is the nation’s seventh largest city, with a population of 11 million people. Over the next few days, researchers at the Wuhan Institute of Virology performed metagenomics analysis using next-generation sequencing from a sample collected from a bronchoalveolar lavage and identified a novel coronavirus as the potential etiology. They called it novel coronavirus 2019 (nCoV-2019).² The US Centers for Disease Control and Prevention (CDC) refers to it as 2019 novel coronavirus (2019-nCoV).³
