A 22-year-old immigration ban preventing those with HIV/AIDS from entering the United States ended on Monday.
President Barack Obama announced he would eliminate that ban in October, a step he said could "encourage people to get tested and get treatment."
"We talk about reducing the stigma of this disease, yet we've treated a visitor living with it as a threat," Obama said in May, according to CNN. "If we want to be the global leader in combating HIV/AIDS, we need to act like it."
The move arrives as the United States prepares to host the World Aids Conference in 2012. The previous travel ban would have severely complicated the White House's ability to participate in the annual forum.
