HIV & AIDS overview
Human immunodeficiency virus, or HIV, is the virus that causes AIDS. In the UK it's estimated there are more than 100,000 people living with HIV. Around a quarter of people with HIV don't know they have the condition. HIV weakens a person’s ability to fight infections and cancer. HIV transmission can occur during unprotected sex or needle sharing. Symptoms of HIV vary widely, with some infected people not showing any signs or symptoms. There is no HIV cure, although medications can delay the onset of AIDS.
