Back 7

an infection not present or incubating at the time of admission to the health care setting

Front 8

host

Back 8

person who provides living conditions to support a microorganism

Front 10

incubation period

Back 10

time between contact and onset of signs and symptoms

Front 11

infection

Back 11

condition in which the host interacts physiologically and immunologically with a microorganism

Front 12

infectious disease

Back 12

the consequences that result from invasion of the body by microorganisms that can produce harm to the body and potentially death

Front 13

latency

Back 14

Staphylococcus aureus bacterium that is not susceptible to extended-penicillin antibiotic formulas, such as methicillin, oxacillin, or nafcillin

Front 15

normal flora
