We just found out that our closest friend has tested positive for antibodies SARS-Cov-2 meaning he might have been exposed to Covid-19. He said he did have a cold some time ago with no fever. We have been with him many times since the pandemic started. We have been with and another friend on a pretty consistent basis, none of us have any major symptom of the virus. We all had been going for Covid testing in the height of the pandemic with consistent negative results. We are now going for antibody tests too as we feel we would have to have been exposed if he was.
