Is COVID test to enter Brazil 24 hours or 1 calendar day?

Pretty sure it’s not required any more

02/19/23 @sakabaro. Follow the instructions on your airline's website. If it says "one day", you can treat it as one calendar day, unless the airline's instructions say otherwise.  Personally, I'd get the test the preceding afternoon, processing times permitting, especially for an afternoon or night flight the next day.

The Brazilian authorities depend on the airline to screen you; if the airline lets you board, you're good to go. Your test status won't be rechecked at Immigration, unless perhaps you're showing obvious symptoms of illness.

Or why not just get a quick vaccine before you go, just to be on the safe side, Then you have the documents to show.

Please don't start this debate here again

Hi,
I've been reading contradictory things online.

Always check with your airline. I have been flying Air Canada and their website now just send me to Anvisa. https://www.gov.br/anvisa/pt-br/assunto … -aeronaves

I wasn’t trying to start a debate. Wasn’t sure how aware the writer was of how available they are and it would be a quick fix

02/19/23  Everybody is just trying to help.  But the rules change regularly, so the most reliable source for information is always your own airline, in the days just before you take off. 

For what it's worth -- which isn't definitive! -- I checked American, the airline I most often fly, before responding to sakabaro's original post.  Their current guidance for Brazil is to get a PCR or Antigen test no more than one day before departure.

I'm hoping all this ends soon. It's become absurd.
