HIV Facts HIV - which causes AIDS - can be transmitted through body fluids, in particular blood, semen, vaginal secretions and breast milk.
Anybody can become infected with HIV, but some groups in the UK have a higher proportion of people living with HIV than others.
This is why investment in prevention needs to be focused on particular groups and why testing, treatment, care and support should especially take into account the needs of these groups of people.
