How Long Ago Would A COVID-19 Infection Be Detected?

Antibodies persist in the body after a viral infection, however, longer-term antibody persistence studies for SARS-CoV-2 have not yet been concluded.

IgG antibodies have been shown to persist for several years for other similar viruses. So it is possible that SARS-CoV-2 antibodies stay in the blood for some time, but we cannot say for certain how long this is without the data to prove it.
