Novel coronaviruses belong to the coronaviridae family and look similar to a crown under microscopic examination, hence the name coronavirus. There are seven types of coronaviruses found clinically, each of which is highly infectious and has different characteristics. Clinically, early detection, isolation and treatment of novel coronaviruses are necessary, especially for early symptoms of patients should be enhanced to identify. Fever, cough, shortness of breath and other respiratory symptoms are easily confused with cold and other diseases. Clinical attention should be paid to observation, isolation as appropriate, and clarification of whether a novel coronavirus infection has developed through nucleic acid testing and chest CT testing. In the later stages of the disease, severe pneumonia, respiratory failure, renal failure, and liver failure, among others, require symptomatic treatment.
