HIV infection -Parasitic retrovirus (virus inserts a copy of its RNA into the DNA of a cell and
changes the cell) that causes immunosuppression making persons more
susceptible to infections
-HIV can be transmitted through contact with certain body fluids (blood, semen,
vaginal secretions, and breast milk)
-HIV is not spread through casual contact (hugging, dry kissing, shaking hands,
sharing eating utensils, using toilet seats)
HIV is an RNA virus -Called retroviruses because they replicate in a "backward" manner, going from
RNA --> DNA, must be in cell to replicate
CD4+T cell is the target cell for HIV -Type of lymphocyte (WBC in the lymphatic system)
-HIV binds to the cell through fusion
-Insufficient immune response allows for opportunistic disease
Immune problems start when CD4+T cell count drops to 500 cells/uL
less than
Severe problems develop when less than 200 cells/uL
CD4+T normal range 800-1200 cells/uL
