 Today is National HIV Testing Day. To learn more about the importance of testing, WTOP's Dick Uliano turned to the Whitman Walker Clinic, which has been a leader in LGBTQ healthcare for more than 50 years. Ramatule Keita, Director of Community Health at Whitman Walker, reminds us that human immunodeficiency virus, which causes AIDS, is still infecting people. It's so important to get tested. It's important to know your status.
