Final answer:
AIDS is caused by HIV and weakens the immune system. Clinical oral presentations can include swollen lymph glands, sores, and a white coating on the tongue. General manifestations include fever, weight loss, weakness, and opportunistic infections.
Step-by-step explanation:
AIDS, or acquired immunodeficiency syndrome, is caused by the human immunodeficiency virus (HIV). HIV weakens the immune system by attacking CD4 T-cells, a type of white blood cell that helps the body fight off infections. When the CD4 T-cell count drops below 200 cells/μL or when certain opportunistic infections occur, a person is diagnosed with AIDS.
The clinical oral presentations of AIDS can include swollen lymph glands, sores in the mouth or throat, and a white coating or discoloration on the tongue. These symptoms may be caused by opportunistic infections like oral thrush or a weakened immune response to oral pathogens.
The general manifestations of AIDS can vary greatly depending on the individual, but common symptoms include fever, chills, sweats, weight loss, weakness, and the development of opportunistic infections and rare cancers.
