Hidden Epidemics in Mexico

Believe it or not, I had a difficult time finding much coverage online about the fact that this recent UN report, while calling the AIDS epidemic "stable" in Latin America, notes that the worst epidemics are in Brazil and in Mexico, attributing this largely to "hidden epidemics." From the fact sheet (link below): "Hidden epidemics of HIV among men who have sex with men are happening in several Central America countries—in Mexico more than half (57%) of the HIV diagnoses to date in the country have been attributed to unprotected sex between men." (emphasis added)

If anyone has information on a good article about this, please share?
