Human Immunodeficiency Virus (HIV) is a virus that attacks the immune system of an infected individual. If untreated, HIV infection can result in acquired immune deficiency syndrome (AIDS).

This is the term used to describe the reduced ability of the immune system to fight infections and illnesses, leading to life-threatening complications. However, people who are HIV-positive but receive treatment on time are likely to remain healthy with normal life expectancy.

Public Health England estimates that there are over 100,000 people with HIV in the UK. 92% know their status, however, around 1 in 12 people who are HIV positive in the UK do not know that they are infected, emphasising the importance of regular testing.
