How many people are living with HIV in the UK and worldwide?
The United Nations Programme on HIV/AIDS (UNAIDS) and the World Health Organization (WHO) released their annual figures for World AIDS Day in 2011. They said that at the end of 2010 there were an estimated 34 million people living with HIV worldwide. In that year, there were 2.7 million new HIV infections. This was 21 per cent below the number of new infections at the peak of the epidemic in 1997.
The worst-affected region is sub-Saharan Africa. In some African countries, over 20 per cent of adults have HIV. The fastest spread of HIV is happening in Eastern Europe and Central Asia. Here, the number of people living with HIV increased by 250 per cent between 2001 and 2010.
The number of people dying of AIDS-related causes fell in 2010 to 1.8 million. This is down from a peak of 2.2 million in the mid-2000s.
Globally, in 2010, 6.65 million people were getting treatment in 2010. However, more than 50 per cent of the people eligible for treatment do not have access to antiretroviral therapy, including many people living with HIV who don’t realise they have HIV.
In the UK, it was estimated that 91,500 people had HIV at the end of 2010, of whom nearly a quarter (24 per cent) did not know they had HIV. Of those living with HIV, 44 per cent were gay men and 45 per cent had been infected though heterosexual sex. Many of those infected heterosexually are black African people. In total, 4.6 per cent were infected through injecting drug use and another 1.7 per cent through mother-to-child transmission.
During 2010, there were 6660 new diagnoses of HIV in the UK.
Over 69,000 people were receiving HIV treatment and care that year and over 90 per cent attended HIV services regularly.
The number of people living with HIV aged over 50 has been increasing. In 2010, 21 per cent of adults were aged 50 years or older, compared with 11 per cent in 2001. Around 58 per cent of all people diagnosed were aged between 25 and 39.
