Brazil 0.3 %
US 0.6 %

(these numbers are from the ministry of health, check the source.)
The HIV prevalence rate in the US is double that of Brazil, and the rate among African Americans then is about 10 times as high, actually AIDS is the LEADING CAUSE OF DEATH among African American women

The HIV numbers for African Americans are very similar to the numbers found in some African countries, so wipe your mouth before you talk about Brazil since our HIV programme is the most sucessful in the Americas and our rate is one of the lowest on the continent.
