As of Janaury 26, all international passengers flying into the United States need a negative COVID-19 test

Just a heads up that as of January 26, all international travelers to the USA, including US Citizens, will need to have a negative COVID-19 PCR test within 72 hours of your flight. There is a similar requirement for entering Brazil.

In Brazil, there is testing at GRU airport in Sao Paulo in Terminal 3 with CR Diagnosticos and they advise that you arrive 6 hours prior to your flight if you are flying the same day to ensure you get your results in time.

Personally, I would not chance it the same day. I would take the time to have it done a day or two ahead of departure at the Guarulhos T3 or the Mooca Shopping location. Probably by train. That’s me. 

If connecting at GRU, given the chances of a delay getting there ... for example, I have been stressed in the past due to my incoming flight being late ... that would put you under pressure at the test location ... it makes sense to have the testing done locally in the last place you are visiting.

This brings us back to the idea of when to get tested in your home country ahead of travelling. If you reside in a region with high CoV prevalence you may want to get tested a week or two prior to your formal departure test, as residual but inactive viral particles might trigger a positive PCR result though you were asymptomatic following infection outside of awareness. That would give you time to organize documentation of recovery and non-infectious status, eg neutralizing antibodies. Similarly, when leaving Brazil you would have on hand the same documentation, having known of your past infection, in the event your inbound test is also positive. That’s me; bred to be thorough. 

I assume that, by now, boarding gate employees are able to interpret a positive test accompanied by verification of non-transmissibility.

PS: Or you might be aware of being recently infected but are an outlier showing positive test results for a few weeks after being non-contagious.

There are a few places in Rio that do same day testing.. you are screwed if you are positive though
