Summary Introduction
To review:
The vulnerability of a patient with AIDS and HIV toward infection and cancer.
Introduction:
Human immunodeficiency virus is a virus that is capable of infecting the immune system of humans and suppressing its functions. This virus is transmitted by blood, semen, vaginal, and rectal fluids, and breast milk. Acquired immunodeficiency syndrome (AIDS) is a disease that is developed with time in people infected with the virus. The initial symptoms of the infection involve influenza-like symptoms.
