Study Notes
Nosocomial Infections
- Also known as health-care-associated (HAIs) or hospital-acquired infections
- Infectious diseases acquired in a health-care facility, specifically in hospitals
- Must develop at least 48 hours after admission
Mode of Transmission of HAIs
- Contact transmission:
- Direct physical contact through touch (e.g., Staphylococcus, HSV)
- Indirect contact through contaminated objects (e.g., instruments, needles, or dressings)
- Respiratory route:
- Airborne aerosols
- Inhalation of droplets or aerosol from respiratory tract secretions (e.g., sneezing, coughing, speaking)
- Food borne:
- Ingestion of contaminated food, water, or drinks
- Vector transmission:
- Through insect bites
- Blood borne:
- Through medical procedures (e.g., Dialysis, Transfusions, Heart Surgery, Injections, Catheterization)
Test your knowledge on nosocomial infections, also known as health-care-associated infections, which are infectious diseases acquired in a health-care facility after at least 48 hours of admission. Learn about the different modes of transmission of HAIs, including contact (direct and indirect), respiratory route (via airborne aerosols and droplets), food-borne ingestion, and vector transmission.
