THE REGION

Free HIV Tests Tomorrow

Free and fast HIV tests will be offered tomorrow at dozens of locations across the Washington region as part of the 11th annual National HIV Testing Day. The event, which this year focuses on the disease's increasing reach into the black and Latino communities, marks the 20th anniversary of the first commercially available diagnostic test for the virus.

The locations include churches, community clinics, universities and health departments, with some offering education, counseling and other screenings on-site. To find a location, go to www.hivtest.org and use the Zip code tool on the front page.

The Centers for Disease Control and Prevention estimates that as many as 280,000 Americans do not know they are infected with HIV.
