Monday, April 18, marks the first-ever National Transgender HIV Testing Day (NTHTD), an event to raise awareness around the issues of HIV prevention and treatment among transgender people, a group disproportionately affected by the epidemic.

The NTHTD campaign is led by the University of California, San Francisco’s Excellence for Transgender Health. The Center has created a Transgender HIV Testing Toolkit, which you can download online for free. The site also includes promotional materials fliers and fact sheets about trans health and HIV, as well as tool kits for health departments.

You can also watch videos of some of the transgender advocates who are part of the Centers for Disease Control’s “Doing It” testing campaign. For example, Shandi Moore, in the video clip above, talks about why it’s important for everyone to know their HIV status and to have honest discussions about sex.

About 0.3 percent of the Unites States population is transgender, which translates to about 700,000 people, according to data presented at the 2016 Conference on Retroviruses and Opportunistic Infections (CROI) and included in the above video on aids.gov. Worldwide, it’s estimated that about 19 percent of transgender women are living with HIV.
