Q

Identify the three parts of the management component in the infection model

A
  • Diagnosis
  • Treatment (specific and supportive)
  • Infection prevention (hospital and community)

important to prevent it spreading to other hospital staff, patients

Q

describe ways that the infection spreads

A
  1. attachment of the pathogen to a cell
  2. toxin production
  3. damage to a host cell

all lead to inflammation

PRRs

A

they bind to the phagocyte receptor

17
