What is the final stage of the HIV virus called?

The final stage of the HIV virus is indeed Acquired Immune Deficiency Syndrome (AIDS). This condition occurs when the immune system is severely compromised due to the prolonged effects of the HIV infection. At this stage, the body's ability to fight off infections and certain diseases is significantly weakened, which can lead to opportunistic infections and specific cancers.

Acquired Immune Deficiency Syndrome is characterized by a marked decrease in CD4 cells, which are essential for the immune response. Individuals diagnosed with AIDS typically present with a range of symptoms and complications that indicate their immune system is no longer able to function effectively.

The other options refer to different concepts: Human Immunodeficiency Virus (HIV) is the virus responsible for the progression toward AIDS but does not represent the final stage itself. Pseudomonacidal does not pertain to HIV, and Herpes Simplex (HSV) refers to a different viral infection altogether. Thus, understanding the terminology is crucial in recognizing how HIV can lead to AIDS, emphasizing the importance of timely diagnosis and treatment to prevent progression.
