In response to an outbreak of respiratory illness, Chinese officials have closed transport within and out of Wuhan and other cities in Hubei province, including buses, subways, trains, and the international airport. Additional restrictions and cancellations of events may occur.
A new coronavirus is causing an outbreak of respiratory illness that began in the city of Wuhan, Hubei Province, China. This outbreak began in early December 2019 and continues to grow. Initially, some patients were linked to the Wuhan South China Seafood City (also called the South China Seafood Wholesale Market and the Hua Nan Seafood Market).
Chinese health officials have reported thousands of cases in China and severe illness has been reported, including deaths. Cases have also been identified in travelers to other countries, including the United States. Person-to-person spread is occurring in China. The extent of person-to-person spread outside of China is unclear at this time.
Coronaviruses are a large family of viruses. There are several known coronaviruses that infect people and usually only cause mild respiratory disease, such as the common cold. However, at least two previously identified coronaviruses have caused severe disease — severe acute respiratory syndrome (SARS) coronavirus and Middle East respiratory syndrome (MERS) coronavirus.
