Infection prevention Control/Mode of transmission
What do we mean by airborne transmission?
Residue from evaporated droplets or infected dust particles can stay suspended in the air for a long time
Air currents make them travel
Infection prevention Control/Mode of transmission
What is an example of airborne diseases?
3 points
Measles- virus
Chicken pox- virus ( varicella- zoster)
TB- bacteria ( breathing in droplets from sneeze or cough )
Infection prevention Control/Mode of transmission
What can you do to prevent direct contact transmission in a clinic ?
Wear a mask / gloves
Offer hand sanitizer to patients
Clean with a low level disinfectant
What can you do (to prevent transmission) if you have a patient that suffers of an air born disease ?
Try to see him at the end of the day
Wear High efficiency N95 masks
Open windows
Offer masks and hand sanitizer
Infection prevention Control
What is Portal of entry?
fifth on chain of infection
Tip: it informs the practitioner on the PPE that may be required
Site where organism can gain access to the host
How the germs get in!
Infection prevention Control
What measures can you take to break the portal of entry “ link” of the chain ?
Wash hands
Aseptic technics during procedures
Taking proper care of wounds ( wear gloves)
Infection prevention control

Mucous membranes
Breaks in the skin
⚡️NEEDLE PUNCTURE
