What are HIV & AIDS? HIV, or human immunodeficiency virus, is a type of virus that infects human immune cells. Over time, immune cells are lost, which weakens the immune system and allows patients to be infected by other viruses. This video explains the pathophysiology behind viral infection, as well as important signs and symptoms of HIV and clinical markers of AIDS. It also gives an overview of diagnosis and treatment. Today is World AIDS Day.
