How Common is HIV?
 
HIV in the UK
 
HIV can affect anybody, but in the UK most 
people with HIV come from two groups:

men who have sex with men 
people of sub-Saharan African origin. 

Gay men are the group most affected by HIV in the UK. However, 
since 2003 more of the people newly diagnosed with HIV in the UK became 
infected through heterosexual sex than gay sex. The majority of these became
infected with HIV when they were abroad. 

While these groups are high profile, it is important not to forget the other people 
who are living with HIV. Around 1,800 people became infected through injecting 
drugs. Just over 1,000 children in the country have HIV because it was passed on 
from their mothers, and about 700 people got infected through blood transfusions 
and blood products.

The Health Protection Agency estimates that about 30% of the people in the 
UK living with HIV do not know that they have become infected.

You can find out more details on the UK pages of the Facts and statistics area.

 

HIV worldwide

The Joint United Nations Programme on HIV/AIDS (UNAIDS) has estimated 
that there are up to 40 million people living with HIV in the world. 
Seventy percent of them live in sub-Saharan Africa. 

In the three worst affected countries - Botswana, Swaziland and Zimbabwe - 
about one in three people is living with the virus. In comparison, there is no 
country outside Africa where more than one in 20 people is living with the virus. 

However, although Africa continues to be the worst-affected region, many of the
countries with the highest rates of growth are outside Africa. These include 
India, China, Russia and most of the other former Soviet states.

A further breakdown is available on the Worldwide
pages of the Facts and statistics area.
