The Chief Executive of the Terrence Higgins Trust highlighted that HIV is "an entirely preventable condition" and regular testing can halt the spread of the virus.
Sir Nick Partridge said:
Thirty years on from the start of the epidemic, public understanding of HIV has dropped to a worrying level.
As a result, we are starting to see a significant increase in the number of heterosexuals acquiring the virus in the UK.
It is important that everyone, no matter their age or background, understands that nobody is immune from infection.
Sir Nick also urged people in high-risk groups to undergo regular HIV testing.
