Detailed explanation-1: -AIDS (acquired immunodeficiency syndrome) is the most severe stage of HIV (Stage 3). People with AIDS have badly damaged immune systems. They get an increasing number of severe illnesses, called opportunistic infections (OIs). their CD4 cell count drops below 200 cells per milliliter of blood.
Detailed explanation-2: -Using T cell count to diagnose AIDS If someone’s helper T cells are below 200 cells/mm3, they will likely receive an AIDS diagnosis. When a person has HIV, a healthcare professional will collect a blood sample and request a CD4 count.
Detailed explanation-3: -HIV destroys CD4 cells by using their replication machinery to create new copies of the virus. This ultimately causes the CD4 cells to swell and burst. When the virus has destroyed a certain number of CD4 cells and the CD4 count drops below 200, a person will have progressed to AIDS.
Detailed explanation-4: -Opportunistic infections (OIs) are infections that occur more often or are more severe in people with weakened immune systems than in people with healthy immune systems. HIV damages the immune system. HIV-related OIs include pneumonia, Salmonella infection, candidiasis, toxoplasmosis, and tuberculosis (TB). More items •16-Aug-2021
