Most people who were diagnosed were gay men, with cases increasing by 70% from 1,810 in 2001 to 3,080 in 2010.
But there is also a high risk among black Africans, which has led to the National Institute for Health and Clinical Excellence (Nice) publishing guidance on driving up testing for HIV among black African communities.
Professor Mike Kelly, director of the centre for public health excellence at Nice, said: “For many people of black African heritage there is a fear that being diagnosed HIV positive will result in social exclusion or racism and prejudice from both inside and outside their community.
“As such there is often a reluctance to be tested which can significantly delay diagnosis.”
The aims of the guidance is to make sure that people living in an area where there is a high prevalence of HIV are regularly offered testing. This can take place when registering with a new GP, on admission to hospital, and when having a blood test.
Three out of five people who die from HIV each year received a late diagnosis.
