What if the seller or buyer has Covid-19 on day of closing?

What happens if the buyer or seller has tested positive for Covid prior to closing and is relatively certain they still have it on day of closing? I realize most title companies at this present time do not have a buyer and seller meet at the same time, but they still would be interacting  a little bit at the closing table with a notary.

All parties sign in their cars respectively and attorney will stand outside in a parking lot and review docs when done. It sounds crazy but this is very much how things are done under this circumstance.
