Restrain i know this for sure
To determine if a person is potentially exposed to a
communicable disease, one should be familiar with the case of the patient. By
then she can determine how the disease will be transmitted by knowing the
portal of entry of the infectious agent and its mode of transmission from
reservoir to a susceptible host by direct or indirect contact.
Moreover, a health professional must be immunized against
infectious disease to lessen the chance of susceptibility of communicable
diseases.
