Rio is at an all time low with no tourists. I was in Rio last week for a while and Dengue Mosquitos are biting a lot of people in the suburbs around Rio de Janeiro. Even my Gym in Ipanema, a Doctor friend got bit on a side street near Leblon. The News shows a horrible scene of poor people standing in long lines for miles waiting for treatment. They have make shift beds and ivs in arms, people just sittingthe North Zone of Rio. That was on the News. From what I understand if you get bit, seek treatment asap or you could die. Because there is no cure.

Routes within Brazil and out are based I think on corruption, who gets paid what. Remember Varig broke from corruption within.
