An outbreak of a new coronavirus disease in 2019 (COVID-19) that began in Wuhan, China has been developing since December 2019. This outbreak now includes hundreds of thousands of cases worldwide and thousands of deaths.
The source of the outbreak has been linked to “wet markets” where live animals are butchered and sold. This new (“novel”) virus is a member of a family of viruses called coronaviruses. Most coronaviruses cause mild disease in humans but some, like MERS and SARS, have been associated with more severe disease.
Since the virus has never been seen in humans, there is no immunity and no vaccine.
