Acquired immunodeficiency syndrome (AIDS) is caused by Human immunodeficiency virus (HIV). HIV infections cause a gradual decrease in CD4+ cells and these cells are an indicator of the immune system including the body’s natural defense system against pathogens and illness.1 AIDS is defined as the advanced stage of HIV infection with CD4 cell count less than 200/mm3. AIDS is characterized by immunosuppression which can result in several opportunistic infections, tumors, and cancers.
