The way to determine if you are infected with the novel coronavirus is to test for the nucleic acid of the novel coronavirus in throat swabs and nasal swabs. Neocoronaviruses are new viruses that are now more widespread and can cause neocoronavirus pneumonia when infected. At present, the main clinical method for determining whether one is infected with the novel coronavirus is the nucleic acid test for the novel coronavirus. Normal people or suspected people can dip respiratory secretions into pharyngeal swabs or nasal swabs for the nucleic acid test after consulting a doctor, and if the result is positive, the diagnosis of the novel coronavirus infection can be confirmed, and if the result is negative, the diagnosis of the novel coronavirus infection can be confirmed. In addition to the above methods, clinical diagnosis can also be made by means of antibody testing for novel coronavirus. If a patient is found to be positive for novel coronavirus-specific IgM antibody and IgG antibody during serologic examination without vaccination against the novel coronavirus, infection with the novel coronavirus can also be confirmed. However, since the detection rate of positive test results within 1 week is low in patients infected with the virus, and the test specimen may be interfered with by rheumatoid factors in the body, false positives may occur, so this method is mainly used as an auxiliary diagnostic method. People with normal nucleic acid test results should wear a mask when going out and avoid going to crowded areas. If the result is positive, the patient should report to the community in time and actively cooperate with the health department for isolation and treatment. Tip: The term “new coronavirus pneumonia” has been renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
