The HIV/AIDS Nightline responds to calls annually from all over the United States. People call for many reasons: testing HIV positive, people who are feeling isolated and/or worried about their medications, caregivers under the stress of caring for a loved one at home, and people worried about the HIV risks. The hours make Nightline a good help and immediate care. For people who got their HIV test results after work to people who just had a night of unsafe sexual exposure.
