What is epidemic?

100

An individual whom harbors a disease-causing pathogen even though they have recovered.

Who is an active carrier.

100

The immediate transfer of an agent from a host to a vulnerable host.

What is direct transmission?

100

The attempt to prevent a disease or disorder before it occurs.

What is primary prevention?

200

This type of epidemiology uses a comparison group and answers the questions of "why" and "how".

When an agent is carried or transferred by an intermediate mechanism to a vulnerable host.

What is indirect transmission?
