MPs have urged continued education about safe sex, during a Westminster Hall debate on cases of HIV on 1 December 2010, World Aids Day.
Leading the debate, Labour MP David Cairns said there needed to be more promotion of the risks of HIV amongst "non-stereotype" groups, such as older people and heterosexuals.
Globally in 2009 there were 2.6m new HIV infections, down almost 20% since the peak of the Aids epidemic in 1999.
In 2009, 1.8m died from Aids-related illnesses, down from 2.1m in 2004.
However the UK's Terence Higgins Trust has warned that a quarter of people with HIV in the UK - around 22,000 - are unaware that they have the virus.
Conservative MP for Hove Mike Weatherley said the figures showed a need for access to early testing, a call backed up by the Shadow Health Minister Diane Abbott.
