Answer 1

The chain of infection, if we think of it as an actual chain, is made up of six different links: pathogen infectious agent , reservoir, portal of exit, means of transmission, portal of entry, and the new host.

The six links include the infectious agent, reservoir, portal of exit, mode of transport, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting this chain at any link.
