HIV is a virus that attacks the body's immune system. It stands for Human Immunodeficiency Virus (HIV).
HIV is the not the same as AIDS. AIDS stands for Acquired Immune Deficiency Syndrome and can develop when HIV damages the immune system to such an extent that it can no longer fight off a range of infections it would normally cope with.
HIV is most commonly passed on through unprotected sex. It can also be transmitted by coming into contact with infected blood - for example, sharing needles to inject steroids or drugs.
The HIV virus attacks and weakens the immune system, making it less able to fight infections and disease. There's no cure for HIV but there are treatments that allow most people to live a long and otherwise healthy life.
AIDs is the final stage of an HIV infection, when your body can no longer fight life-threatening infections.
Most people with HIV will look and feel healthy and have no symptoms. When you first develop HIV you may experience a flu-like illness with a fever, sore throat or rash. This is called a seroconversion illness.
A simple blood test is usually used to test for an HIV infection. Some clinics may also offer a rapid test using a finger prick blood test or saliva sample.
