I understand the point, but it really si not quite accurate. Keep in mind that the COVID-19 cases in Brazil came form the US. To suggest that the US is protecting itself is laughable. Protection requires comprehensive testing and aggressive case epidemiology.
Neither Brazil nor the US has either of those.
Flying in Brazil, where possible does include quite comprehensive evaluation prior to flight. Indeed poor people suffer. Rich ones do not. The statistics everywhere indicate that. Poor people do not fly much.
From a statistical perspective flying is less risky than many other activities. Partly that is because aircraft filtration has been upgraded, aircraft interiors are sterilized, crews and passengers are screened and food service has been curtailed/modified. Almost all respectable airlines are doing those things.
I am not suggesting air travel is risk free, far from it. I am stating that no significant international airline neglects protection against viral spread today. That said I will not travel in the immediate future.
FWIW, I normally fly 12-15 international round trip per year. I have now been on the ground for the longest period in my adult life. I admit it, I'm stir-crazy!
For anybody who deigns to travel to Brazil I recommend GOL or Latam, both of which are assiduous regarding cleanliness. Given the current situation were i to travel to the US I'd probably choose either Lufthansa or KLM via EU unless Latam would fly non-stop from GIG.
For all of us, though, air travel is no longer the risk it was in December and January. Now politics are dominating science.
I would not get on a plane without an N95 mask and an awful lot of personal disinfectant. In fact I would probably put a cloth mask over the N95 mask. Even with that combination I might only get on an airplane unless I was reasonably convinced that no one was going to sit next to me, and I had no other option for essential travel. With all those contingencies driving the Tesla looks better and better. Won't get me to Europe but I think it's going to be my transportation in the US for quite a while
