Endogenous Infection

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.)
