Forty years ago today the world changed forever with the first reported cases of what we now know to be HIV.

Since then, more than 30million lives have been lost to the epidemic. We've come a long way in the fight against HIV and seen huge medical progress – but it's not over.

Terrence Higgins Trust is the UK's leading HIV and sexual health charity. We support people living with HIV and amplify their voices, and help the people using our services to achieve good sexual health.
