What is caused by the human immunodeficiency virus? helper T cells
viruses. All four of those infectious diseases are caused by viruses. Human Immunodeficiency Virus (HIV) is the name of the virus that causes AIDS. The common cold is usually caused by the rhinovirus (up to 40% of colds), or Coronaviruses (about 20%), but there are more than 200 viruses that can cause the common cold. Viruses also cause the flu, there are three types of human influenza viruses, Types A, B and C and many subtypes and strains of each of those types.
The main cause of immune system disorder is expose of closed self antigens those were not recognised by body immune system's antibodies against these self antigens started to produced that combined with it and causes inflammations
Probably the disease most commonly recognized as a disease of the immune system is Human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS), which is known as a secondary immune deficiency disorder (secondary = caused by something acting on the body, like the HIV virus that causes AIDS, as opposed to being primary = caused by inherited genetic mutations). There are many primary immune deficiency disorders, but these are less well-known, examples are: Severe Combined Immunodeficiency (SCID) and Selective Immunoglobulin A Deficiency.Other diseases or disorders that affect the immune system are those that cause autoimmune diseases, such as Lupus Erythematosis, Rheumatoid Arthritis, Multiple Sclerosis, and Pernicious Anemia. These cause the the immune system to get confused and attack your cells as if they are foreign invaders to try to destroy the cells.There are also medications that can affect the immune system to depress the immune response so that people with transplanted organs do not have the immune system attacking the "foreign" organ and creating "rejection".
Heart diseases are among the most common causes of death.

Infection secondary to trauma.
HIV is the virus. AIDS is the disease caused by the virus. (So HIV is not actually a disease per se.) As an analogue - the H1N1 virus can cause the flu.
