Suspected infections of novel coronavirus pneumonia can be confirmed by pathogenic testing. How to determine if you are infected is first to determine if you have a history of epidemiological exposure, such as having had close contact with a person infected or suspected of being infected with the virus, or having traveled to or lived in an infected area. Secondly, symptoms such as fever, dry cough and general malaise should appear within 14 days after the contact occurred. When these symptoms occur, you should promptly go to the fever clinics around the world for formal examinations, including routine blood tests, lung CT, and pathogenic examinations.
