2019 Novel Coronavirus-Important Information for Clinicians.
Author information 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.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).The US Centers for Disease Control and Prevention (CDC) refers to it as 2019 novel coronavirus (2019-nCoV).
As of February 4, 2020, more than 20 000 cases of 2019-nCoV have been reported, 98.9% of them in China, and the outbreak is linked to more than 400 deaths. As the epidemic is evolving and the situation is rapidly changing, up-to-date reliable information on the number of cases and recommendations on management of cases and preventive interventions can be found at various sites, including the webpage developed by the CDC.3 Currently the number of infections outside of China remains small (approximately 180), but cases have been detected in 26 countries, including 11 cases in the United States.
