[Infographic] How to Study: HIV Susceptible Diseases by CD4+ Count

This is an infographic explaining the opportunistic infections seen with HIV, organized by the CD4+ count they arise at.

HIV Susceptible Diseases by CD4+ Count

Some topics you will learn in this infographic:

CD4* < 500:
During the symptomatic period, the patient’s CD4+ T cell counts decreases to < 500 cells/µL. As the viral load in the bloodstream increases, the patient’s immune system has decreased reserves to fight off opportunistic infections and symptoms worsen.

AIDS:
The patient with HIV will be diagnosed with AIDS. The patient’s immune system is severely compromised and highly susceptible to infections. Diagnostic criteria for AIDS includes a CD4+ T cell count of < 200 cells/µL, CD4+ T cells accounting for less than 14% of all lymphocytes, an opportunistic infection, an opportunistic cancer, wasting syndrome, or AIDS dementia complex. A patient diagnosed with AIDS will remain infected for the rest of their life.

CD4* < 200:
