Fifteen years ago, when Pedro Zamora appeared on MTV’s The Real World, he changed the face of HIV/AIDS in America.

For the first time, viewers saw an openly gay, HIV-positive young person on national television. As we followed his story each week, Pedro humanized the growing epidemic, reducing our ignorance and fears and increasing our determination to act. By living bravely and allowing MTV to show his story, Pedro set an extraordinary example of what a tremendous impact a single person can make in our world.

Pedro’s story and his message remain powerful and relevant. Today, more than 1 million Americans are living with HIV, and 20 percent of them don’t know they are infected. Infection rates are increasing among certain groups, including women of color. The HIV infection rate in Washington, D.C. – at 3 percent – is comparable to some African countries where AIDS is the number one cause of death.

It’s critical for our nation to intensify the fight against HIV/AIDS here at home, starting with testing. Lack of information, misconceptions, and social stigma keep too many people from getting tested. Others mistakenly believe they have been tested as part of routine health care visits. Rapid result tests, including basic oral swabs, make it easy for anyone, anywhere in the country to be tested for HIV. Non-invasive testing is also available for other, more prevalent STDs, including chlamydia, gonorrhea.

Today marks the start of National STD Awareness Month. Several organizations on the frontlines of the HIV/AIDS and broader STD efforts are beginning a concentrated push to get as many people tested as possible this April. This is an opportunity especially for younger people who have never lived in a world without the threat of HIV/AIDS to confront these challenges head on. I urge all Americans, particularly those under age 25 who are sexually active, to get tested for STDs and make responsible decisions about their sexual health. Our actions now will shape the future of the AIDS epidemic and our country’s health.
