Human Immunodeficiency Virus (HIV) is a viral infection that can be sexually transmitted. When someone becomes infected with HIV the virus weakens and damages their body’s immune system so that it cannot fight off infection.

A person is only diagnosed with Acquired Immune Deficiency Syndrome (AIDS) when their immune system cannot cope and they develop one or more particular illnesses.
