Study Notes
Cross-Infection
- Transmission of infectious agents among patients and staff in a clinical environment.
- Sources of infection include patients with infectious diseases, patients in the prodromal stage of infections, and healthy carriers of pathogens.
Chain of Infection
- Involves a reservoir (e.g., people, equipment, water) as a source of the infection.
- A portal of exit (e.g., secretions, excretions, droplets, skin) allows the infectious agent to leave the reservoir.
- The chain of infection likely includes other stages like a mode of transmission, a portal of entry, and a susceptible host.
