HIV (Human Immunodeficiency Virus) is a virus that weakens the immune system and makes it difficult to fight diseases and infections.
AIDS (Acquired Immunodeficiency Syndrome) is a combination of having HIV and one or more infections or diseases. Because HIV has damaged the immune system, the body can’t protect against or fight infections or diseases, and a person becomes very sick. There is no cure for HIV, but it can be treated. Medication, known as highly active antiretroviral therapy, can be taken to lower the amount of virus in the body, and keep the immune system strong, allowing people with HIV to live long, healthy lives.
