Which stage of the human immunodeficiency virus (HIV) would a client with a CD4 T cell count of 325 cells/mm3 be classified
kirza4 [7]

Based on the CDC guidelines a person with a CD4+ cell count between 200-400 is regarded as being in <u>the second stage</u> of the HIV infection.

Acquired Immunodeficiency Syndrome

Acquired immunodeficiency syndrome (AIDS) is a condition caused by HIV (human immunodeficiency virus). AIDS is a chronic disorder and can become life-threatening for the infected person. The HIV viruses reproduce inside the host and while doing so they destroy the CD4+ immune cells which reduce the person's ability to fight against other diseases.

CD4+ cell count and AIDS

According to the CDC (U.S. Centers for Disease Control and Prevention), HIV infection is categorized into different stages based on the number of CD4+ cells.

  • Stage 1: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
  • Stage 2: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
  • Stage 3: - The CD4+ cell count falls below 200 and AIDS-related symptoms and conditions are present.
