Study Notes
Susceptible Host
- Infection acquisition is linked to an individual's susceptibility to infectious agents.
- Susceptibility varies based on the person's resistance to pathogens.
- Constant exposure to microorganisms does not lead to infection unless susceptibility increases.
- Higher virulence of an organism correlates with greater susceptibility in individuals.
- Antibiotic-resistant organisms are becoming prevalent in acute care environments, exacerbated by misuse of antibiotics.
- Vaccination or previous infection can enhance a person's resistance to specific infectious agents.
