The primary objective of this testing is to reduce the transmission of SARS-CoV-2 in the community, where there are concerns for introduction and widespread transmission, by quickly identifying and isolating people who are infected. Positive results of the first follow-up antigen test were evaluated by demographic characteristics, symptom status, previous infection, vaccination status, and number of days since symptom onset or a positive test result. Despite this, the sudden drop in viral load means testing too late might produce a false negative. People who have had severe COVID-19 may be contagious for up to 20 days.

An infection with the SARS-CoV-2 virus may cause new or worse symptoms. It is important to consider these factors especially if a person has limited access to tests. In general, for all diagnostic tests, the lower the prevalence of infection in the community, the higher the proportion of false positive test results. For example, a higher likelihood of SARS-CoV-2 infection would be a person who has had close contact or suspected exposure to a person with COVID-19. ** Defined as days since symptom onset if symptomatic, or days since the initial NAAT or antigen test if asymptomatic.
