A positive neocoronavirus antigen test does not confirm the diagnosis of neocoronavirus infection. The antigen test can be used as a supplemental tool, and the new crown nucleic acid test is the definitive basis for the new crown virus infection; if you find that the antigen test is positive, you should get a valid document and go for the new crown nucleic acid test in a timely manner, as the result of this test is the gold standard for the new crown virus infection. Patients infected by the New Crown virus may have symptoms such as fever, headache, loss of sense of smell, coughing and chest pain, and there are also asymptomatic infected people. Neocoronaviruses are relatively strong transmitters, so it is important to be aware of the need for precautions. People who are in contact with patients with New Crown Pneumonia should do antigen testing and also nucleic acid testing in a timely manner to avoid delaying the disease and spreading it to others, and those who have traveled to an infected area or have had close contact with an infected person need to take the initiative to report the disease. Do not self-medicate when you have symptoms of CKP, but go to a specific medical institution for isolation and treatment in a timely manner. Tip: In this article, the terms “new coronavirus pneumonia” and “new coronavirus pneumonia” were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
