Novel coronavirus pneumonia is a very serious disease that is very dangerous. It is a category B infectious disease in our country, but is managed as a category A infectious disease. After infection, patients mainly present with symptoms of the lower respiratory tract, with fever, malaise and dry cough. In severe cases, patients may suffer from respiratory failure or even death due to the rapid progression of intrapulmonary lesions. Most of these patients have a combination of underlying diseases, such as liver cirrhosis, diabetes, etc. If the patient progresses to severe disease, the mortality rate can be as high as 50% or more. Because the novel coronavirus is very contagious and can infect a large number of people in a short period of time, it causes a very high number of deaths and there is no effective drug to cure it, making it a very serious disease.
