Which stage of HIV is characterized by a severely compromised immune system?

The stage characterized by a severely compromised immune system is known as AIDS (Acquired Immunodeficiency Syndrome). At this point, the HIV virus has significantly weakened the body's immune defenses, leaving the individual highly susceptible to opportunistic infections and certain cancers.

During this stage, the CD4 T cell count drops below 200 cells/mm³, which is a critical threshold for immune function. The progression to AIDS signifies that the HIV infection has advanced despite treatment or that the person has not received adequate care.

This stage can have serious consequences, as the body's inability to fight off infections becomes critical, and even common illnesses can become life-threatening. Treatment at this stage focuses on managing infections and conditions that occur as a result of the severely weakened immune system, as well as continuing antiretroviral therapy to prolong life as much as possible.

Understanding this is crucial for recognizing the importance of early detection and intervention in individuals living with HIV, as timely access to treatment can help prevent the progression to AIDS.
