1.1 Definition

• Definition and terminology of nosocomial infections (healthcare-associated infections)

1.2 Causes

• Pathogenesis and transmission routes
• Common sources of infection in healthcare settings

1.3 Common Pathogens

• Bacteria (e.g., Staphylococcus aureus, Pseudomonas aeruginosa)
• Viruses (e.g., Hepatitis B & C, Influenza)
• Fungi (e.g., Candida spp.)

1.4 Impact on Healthcare Settings

• Morbidity and mortality
• Increased length of hospital stay
• Economic and resource burden

2. Risk Factors for Nosocomial Infections
