Novel coronavirus pneumonia is caused by a novel coronavirus, which is the same coronavirus infection as SARS in 2003 and Middle East Respiratory Syndrome (MERS) in 2012. The new coronavirus is highly contagious, and currently there are confirmed cases in most areas of the country. In mild cases, the symptoms may resolve on their own in 5-7 days, but in severe cases, serious complications such as ARDS and sepsis may occur. It is recommended to take good protection and avoid unnecessary going out.
