World AIDS Day, held every year on 1 December since 1988, is an opportunity to unite in the fight against HIV, show support for people living with HIV and to commemorate people who have died.
Doctors, health officials and members of the public around the world take part in events that promote awareness and understanding of the pandemic.
OpenLearn has published a variety of articles and study units that you can access to learn more about HIV and AIDS and other important issues in health.
Find links to several of them below, as well as to the World AIDS Day website, where you can read more about the campaign, find events and make a donation. You can also use the hashtag #HIVNotRetro to spread positive thoughts on social media.
