What is hiv?

No; AIDS (Acquired Immune Deficiency Syndrome) is a late stage of HIV infection. AIDS is diagnosed when a person with HIV infection has a severely damaged immune system so that they develop a disease caused by an organism that doesn’t usually affect healthy people. AIDS is also present if a person with HIV infection develops certain kinds of cancers. People with HIV infection who are on effective treatment do not develop AIDS, as the treatment stops damage to the immune system.

Most people have mild symptoms or no symptoms when they are first infected with HIV. Some people develop a flu-like illness with fever, sore throat, swollen glands or a rash a few weeks after being infected. These symptoms usually disappear without treatment after a week or two. This is called the seroconversion illness. After the initial illness, people with HIV infection usually have no symptoms for many years, despite the virus living in their body.
