answer
        Infectious agent: the organism (such as Clostridium difficile)  Reservoir: Patient 1  Portal of exit: bowel movement of Patient 1  Mode of transmission: nurse's hands, because this organism is not killed by alcohol-based hand gel  Portal of entry: Patient 2's mouth  Susceptible host: Patient 2
question

question
            localized infection
answer
        infection is in one area of the body
question
            systemic infection
answer
        if infection spreads from one site to another site, such as from lungs to other organs it becomes systemic, spreading through the bloodstream
question

answer
        systemic infection, because when microorganisms are present and multiplying in the blood, it is referred to as septicemia-
question

question
            How does lack of rest decrease the body's ability to defend itself against infection
