Thinking of your current or a past practice area provide an example of the train of transmission specific to that area. Fill in all ‘links’ in the chain with an example for each link:
Portals of Exit:
Modes of Transmission:

I agree with you , we should do hand washing in proper way , and another important thing is , make sure when we are sick be more cautious at work . Either stay home till getting better or use proper PPE .
I agree with you. Hand Hygiene is crucial. I complete hand hygiene audits several times a week at work and I have had to provide 1:1 education with the staff. I also hear about staff coming in to work despite being sick. I agree with that you the person should stay home until they are better.
Infection agent: Covid 19
Reservoir: resident with COPD
Portal of exit: respiratory secretions

Modes of Transmission: touching surfaces that are contaminated with feces and then touching the mouth
Portals of Entry: mouth
Susceptible Host: long-term use of antibiotics, consuming infected food or water; an immunocompromised person
Great discussion everyone. I really like to see you engaged with your fellow professionals. As nurses, we can always learn from one another.
MRSA example has been one of the nosocomial infection that I have seen in hospital setting because it spread by direct contact with contaminated hands. So the 4 moments of hand hygiene, cleaning equipment after each use and educations staff will help to prevent the spread of the bacteria.
Going through the last few years has made me and others I am sure more cautious at home related to cleaning of high touch surfaces like light switches etc on a daily or more basis. As well working in the community cleaning of our vehicles high touch areas.
Hi Tina, I also think it is important to maintain a good hygiene such as hand washing, cleaning of high touch surfaces on a daily basis, not only in our workplace, also at home.
I agree, one positive outcome is how even stores are more cautious and routinely have hand sanitizer and spray to keep the carts clean. I feel covid has increased the general publics knowledge on I.C.
