For college students, HIV infection is the same as any other population, regardless of the stage and current immune function, and requires early antiretroviral treatment. The general procedure is for the diagnosing organization to notify the local CDC, which will refer the patient to a designated hospital for free antiretroviral medication, and will require regular review during the treatment process. AIDS, also known as acquired immunodeficiency syndrome, is a group of syndromes caused by HIV and characterized by immune system damage and infection, mainly through blood transmission, sexual transmission and vertical transmission from mother to child.
