National HIV, STD, and Hepatitis Testing

What is National HIV Testing Day?

National HIV Testing Day (NHTD) is an annual observance to encourage people of all ages to get tested for HIV and to know their status. Too many people don't know they have HIV. At the end of 2014, an estimated 1.1 million persons aged 13 and older were living with HIV infection in the United States, including an estimated 166,000 (15%, or 1 in 7) persons whose infections had not been diagnosed. Getting tested is the first step to finding out if you have HIV. If you have HIV, getting medical care and taking medicines regularly helps you live a longer, healthier life and also lowers the chances of passing HIV on to others.

Testing is the only way for the Americans living with undiagnosed HIV to know their HIV status and get into care. CDC estimates that more than 90% of all new infections could be prevented by proper testing and linking HIV positive persons to care. HIV testing saves lives! It is one of the most powerful tools in the fight against HIV. For more information about National HIV Testing Day and how your agency can get involved, visit: https://npin.cdc.gov/nhtd
