Acquired Immunodeficiency syndrome is a potentially life-threatening issue. It is caused by the HIV. HIV attacks and weakens the immune system, specifically the CD4+ T cells, which are a type of white blood cell that plays a critical role in the body's defence against infections. AIDS is the most advanced stage of HIV infection, characterized by severe immunosuppression and increased vulnerability to opportunistic infections, which are infections that take advantage of a weakened immune system. Common opportunistic infections associated with AIDS include pneumonia, tuberculosis, candidiasis (a fungal infection), cytomegalovirus (CMV) infection, and various types of cancers, among others.
The symptoms of AIDS can vary widely depending on the opportunistic infections or cancers that may develop, but they may include persistent fever, fatigue, weight loss, frequent infections, skin rashes, night sweats, diarrhea, oral thrush, and swollen lymph nodes, among others. There are various diagnostic procedures that are usually recommended by the doctor for diagnosing the HIV/AIDS such as AIDS/HIV 1 and 2 Antibody, HIV Viral Load, HIV 1 and 2 Elisa, HIV PCR etc.
