US secretary of state Hillary Clinton and former US president George W Bush are headed for an HIV conference being held in Washington this week.
This will be the first time since 1990 that the US has hosted the event – the conference has been unable to visit the US due to a law that restricted HIV-positive people entering the country.
President Barack Obama repealed the law in 2009.
President Obama will not be at the conference, but is sending a video message and will host a reception on HIV/AIDS later this month.
A White House spokesperson said, “Under the president’s leadership, the administration has increased overall funding to combat HIV/AIDS to record levels. We have launched the first comprehensive National HIV/AIDS Strategy for the United States to prevent and treat HIV in America. Globally, the Obama Administration has committed to treating six million people by the end of 2013 and is increasing the impact and sustainability of our investments.”
