Researchers, policy makers and activists are busy preparing for the International AIDS Conference. The next conference begins Sunday in Vienna, Austria.

On Tuesday, the Obama administration announced its National HIV/AIDS Strategy. The plan aims to reduce new HIV infections by twenty-five percent within five years. It also aims to make sure infected patients get treatment more quickly.

HIV is the virus that causes AIDS. The government says sixty-five percent of Americans who discover they are infected get treatment within three months. The new plan calls for increasing that to eighty-five percent.
