After COVID-19 infects the human body, it first propagates in the respiratory system, so we can determine whether the human body is infected by detecting the viral nucleic acid in sputum and nasopharyngeal swabs. After a period of infection, usually 7-10 days later, the human body will produce specific antibodies against the virus. IgM antibody appears first, and then IgG antibody appears. Therefore, immunological detection methods can be used to detect these specific antibodies to determine whether the human body has been infected with virus.
