Is the flu a new type of coronavirus pneumonia?

The new coronavirus pneumonia manifests itself as fever, cough, etc. The common cold in the general population can also manifest itself as fever, sore throat, cough, runny nose, etc., but these two are completely different diseases. Colds are upper respiratory tract infections caused by a variety of viruses, including respiratory syncytial virus, but also other types of coronaviruses. Novel coronavirus pneumonia is a lower respiratory tract infection caused by a novel coronavirus, and there is a clear distinction between the two. The common cold is characterized by upper respiratory symptoms such as runny nose, fever, and cough, whereas novel coronavirus pneumonia often presents with fever and deep cough with impaired respiratory function. The appropriate pathogenetic tests can help to differentiate between colds and novel coronavirus pneumonia. Source: Dr. Yurai
