The reopening November 1st is a clear clue.

At the moment, I'm in a required hybrid work mode and if the USA continues to insist on a negative COVID-19 test to return, it's a risk I probably should not take unless we revert to work-from-home (at least as an option) in the meantime. OTOH, if I were to test positive for some reason even at home, presumably I shouldn't go near my office for two weeks, so this might be a way around the rules.

Is it known what happens in Argentina when a fully vaccinated foreigner gets a positive COVID-19 test?

I'd like very much to return to BsAs for another COW DO and the Thanksgiving dates would work well for me, assuming flight and hotel availability.

ADDED: I just realized that the dates would be the weekend before USA Turkey Day. Assuming flight schedules would be similar to what they always were, I assume that I would be arriving on Saturday morning (not Friday) and departing whenever.
