Your immune system can also be weakened by smoking, alcohol, and poor nutrition. AIDS. HIV, which causes AIDS, is an acquired viral infection that destroys important white blood cells and weakens the immune system. People with HIV/AIDS become seriously ill with infections that most people can fight off. Worldwide, the most common causes are HIV, malnutrition, and unsanitary conditions. However, about one in 500 patients has an innate or primary immunodeficiency. Immunodeficiency disorders usually result from use of a drug or from a long-lasting serious disorder (such as cancer) but occasionally are inherited. People usually have frequent, unusual, or unusually severe or prolonged infections and may develop an autoimmune disorder or cancer.
