The HIV blood test detects anti-HIV antibodies. Why do viruses stimulate antibody production? How effective are antibodies against viruses, as compared to bacteria? How are viral infections normally eliminated in the body? Why does a person's immune response fail to eliminate life -long viral infections such as HIV and herpes? Explain all of your answers.
What will be an ideal response?
Viruses have antigens, thus they stimulate the humoral immune response as well as the cell-mediated response.
Antibodies are less effective against viruses because viruses "hide" inside cells, and antibodies do not enter cells.
Viral infections can be eliminated by the cell-mediated response, which destroys virus-infected self cells. Life-long
virus infections are possible because some viruses persist inside of cells without altering them in a way that
stimulates immune attack.
