If the patient has the typical symptoms of new coronavirus pneumonia, such as fever, malaise, dry cough, some patients will be accompanied by loss of taste and smell, a history of living in high-risk areas, or close contact with patients with new coronavirus pneumonia, two bands of the new coronavirus antigen test is very likely to indicate infection with the new coronavirus, and need to be reported to the fever clinic in a timely manner to complete the nucleic acid test. Tip: “New coronavirus pneumonia” and “new coronavirus pneumonia” mentioned in this article have been renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
