any organism of microscopic size

way that the causative agent can be transmitted to another reservoir or host where it can live

part of the normal flora of the body and are beneficial in maintaining certain body processes

hospital acquired infection

Microorganisms that are normal residents of a host but can cause illness when the host's defenses are weakened by such factors as poor nutrition or a recent bout with the flu.

an epidemic that is geographically widespread
