What are the six elements of the chain of infection?

The 6 points include: the infectious agent, reservoir, portal of exit, means of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting the chain at any link. The host is any carrier of an infection or someone at risk of infection.
