The test refers to the Neocoronavirus antigen test, where two bars usually indicate a positive Neocoronavirus infection. A common fever does not result in a positive Neocoronavirus test; a fever caused by infection with Neocoronavirus may result in a positive Neocoronavirus test. A normal fever may be infectious, such as those caused by infection with various bacteria, parasites, or other viruses that do not contain Neocoronaviruses, or non-infectious, such as those caused by aseptic necrotic tissue resorption, metrorrhagia, or malfunctioning of the thermoregulatory center. This type of fever does not contain neocoronavirus in the body and will not result in a positive test for neocoronavirus antigen. On the other hand, patients with fever caused by neocoronavirus infection contain neocoronavirus in their bodies, so they may test positive for neocoronavirus antigen. If the test is positive, the patient should immediately report to his/her community and be transferred to a designated medical institution for nucleic acid testing according to the relevant regulations. If the test is positive, the patient should immediately cooperate with healthcare personnel for active isolation and treatment. Patients who test positive for new crown antigen should wear a mask throughout the journey to the hospital and do a good job of self-health monitoring.
