Delegates at the 17th National Health conference will discuss 20 proposals on the health of the migrant population
A little context: In Brazil, public free health care is universal. You may be homeless, a legal or illegal immigrant, a tourist, undocumented, never having paid insurance or taxes, but you have the right to use the health care system. As it should be, everywhere.
Keep in mind the health care isn't exactly the best and you'll probably be in a queue for a while, but at least you don't go bankrupt after a visit to the hospital.
I know, I'm Brazilian! It's the largest public health system in the world, and Brazil is not (yet haha) a superpower, so all things considered (and despite all the corruption), they do a pretty good job. In some regions it's even decent, once you survived the lines.
