Final answer:
EBV infection can result in lymphocytosis, which is an abnormally high lymphocyte count. CD8+ T cells are a specific subset of lymphocytes that increase in response to EBV infection.
Step-by-step explanation:
EBV infection can result in lymphocytosis, which is an abnormally high lymphocyte count. Lymphocytes are a type of white blood cell that play a key role in the immune response. CD8+ T cells are a specific subset of lymphocytes that are involved in the cell-mediated immune response. When a person is infected with EBV, the body produces more CD8+ T cells as part of the immune response to control the infection. This leads to an increase in the overall lymphocyte count in the blood.
