Exogenous Infection
Hospital Acquired Infection Hospital Factors:
- Air and Water Supply (eg. Legionella)
- Fomites
- Hospital Food
Patient Factors:
- Reduced personal hygiene
- Lowered resistance secondary to primary disease
- Overcrowding facilitates disease dissemination
Healthcare Factors:
- Cannulation (48hrs)
- Catheterisation (Introduction of bacteria, biofilm, facilitating retrograde travel)
- Staff as Vectors (Handwashing, Short Sleeves etc.)
