HIV Progression and AIDS Explained
Human Immunodeficiency Virus (HIV) primarily targets and damages the body's immune system, specifically the CD4 cells (T cells) which are crucial for fighting infections.
Acquired Immunodeficiency Syndrome (AIDS) represents the final, most severe stage of HIV infection. It is diagnosed when the immune system is significantly compromised due to HIV.
When HIV infection remains untreated, the virus continuously replicates, destroying more CD4 cells over time. This progressive decline severely weakens the immune system, making the individual highly susceptible to opportunistic infections and certain cancers. This critical state of immune deficiency is defined as AIDS.
Therefore, the natural progression of untreated HIV infection leads to AIDS.
