National HIV Testing Day is here, with numerous clinics and medical centers opening their doors to offer free, confidential HIV tests.

According to the CDC nearly 1.1 million people are living with HIV in the U.S. alone, and almost one in six don't know they are infected.

Getting tested is the first step: If you have HIV, getting medical care and taking medication regularly will help you live a longer, healthier life and lowers the chances of passing HIV on to others. In fact, early diagnosis and treatment can extend your life and prevent transmission by as much as 96%.

Knowing your status makes you and your community stronger.

As part of National HIV Testing Day, Walgreens has teamed up with Greater Than AIDS to offer free HIV tests in more than 250 stores nationwide. Head over to the Center for Disease Control's website or download the new locator app to find the  location nearest to you.

Share your support on social media with the #NHTD campaign on Twitter and Pinterest or share your own HIV/AIDS story or testimony on the AIDS.gov blog. For more information, visit AIDS.gov.
