Overview

Coronaviruses have a worldwide distribution, causing 10-15% of common cold cases. Infections show a seasonal pattern with most cases occurring in the winter months. Coronavirus infection is very common and occurs worldwide. The incidence of infection is strongly seasonal, with the greatest incidence in children in winter. Adult infections are less common. The number of coronavirus serotypes and the extent of antigenic variation is unknown. Re-infections appear to occur throughout life, implying multiple serotypes (at least four are known) and/or antigenic variation, hence the prospects for immunization appear bleak.

Recent Outbreaks

2019-nCoV

Global

• An outbreak of pneumonia of unknown etiology in Wuhan City was initially reported to WHO on December 31, 2019. Chinese health authorities have confirmed more than 40 infections with a novel coronavirus as the cause of the outbreak. Reportedly, most patients had epidemiological links to a large seafood and animal market. The market was closed on January 1, 2020. Currently, Chinese health authorities report no community spread of this virus, and no transmission among healthcare personnel caring for outbreak patients. No additional cases of infection with 2019-nCoV have been identified in China since January 3, 2020.

• On January 13, 2020 public health officials in Thailand confirmed detection of a human infection with 2019-nCoV in a traveler from Wuhan, China. This was the first confirmed case of 2019-nCoV documented outside China. On January 17, 2020 a second case was confirmed in Thailand, also in a returned traveler from Wuhan City. On January 15, 2020 health officials in Japan confirmed 2019-nCoV infection in a returned traveler from Wuhan City. These persons had onset dates after January 3, 2020. These cases did not report visiting the large seafood and animal market to which many cases in China have been linked.

• On January 11, 2020, CDC updated the level 1 travel health notice (“practice usual precautions”) for Wuhan City, Hubei Province, China with additional information (originally issued on January 6, 2020)
