In AIDS there is the destruction of the blood CD4 lymphocytes by the virus.
Explanation:
CD4 cells are a type of immune cell that is found in the blood. This cell count is a measure of the number of these cells in a milliliter of blood. It is an important indicator of immune health.
When the CD4 count gets lower than 200 mm3 the patient is more prone to get opportunistic infections like rare fungal infections, Tuberculosis, Mycobacterial infections, parasitic infections, etc.
The CD4 count is used to measure to identify an immune deficiency in people.
