June 27; The National Association of People with AIDS (NAPWA) started National HIV Testing Day (NHTD) in 1995. Every year, local organizations across the nation engage with communities to promote early diagnosis and HIV-testing. The Centers for Disease Control and Prevention (CDC) estimates that more 250,000 of the 1.6 people living with HIV/AIDS in the United States are unaware of their status.
