Novel coronavirus is a newly discovered virus that is found in wild animals and has been shown to be human-to-human and very contagious. The virus is spread by droplets from coughing, sneezing, etc., and can also be spread by contact or possibly by aerosols. There is no specific treatment for this virus, so there is a great risk if the disease is not treated in a timely manner in a hospital, the mortality rate is not high, but it does require close observation and attention. The early detection and treatment of mild cases can be cured. However, care must be taken to ensure good protection against cross-infection.
