| Q: What are viruses? A: Viruses are non-living parasites that enter healthy cells, and take over their functioning, so that the cells begin manufacturing more viruses until the cell is engorged with viruses and dies, releasing the viruses to hunt other cells. Antibiotics (special prescription drugs) can't kill viruses, since viruses aren't living. Antibodies, manufactured by B-cells can isolate viruses to help the T-cells destroy them.
