Document Summary

Host: either a person or a population that contacts one or more agents in an environment. Vector: a biological or physical vehicle that carries the agent to the host, providing the means of transmission. Tough tiny pathogens that consist of a bit of nucleic acid with a protein coat. Unable to reproduce on its own so it must invade a living cell to reproduce. Before it dies because the cell can no longer preform its normal functions, the cell releases new viruses which are then released to enter other cells. Some alter the cells functions, instead of kill the cells, which can become cancerous. Antibiotics: drugs that inhibit or kill bacteria (have no effects on viruses) Antiviral drugs: can decrease its severity and duration. Simple one-celled organisms that have a rigid cell wall and a thin, rubbery cell membrane that surrounds cytoplasm inside the cell.
