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:

Infectious Agent:

Reservoirs:

Portals of Exit:

Modes of Transmission:

Portals of Entry:

Susceptible Host:

an example of the chain of transmission as a past PSW in long-term care is:

infectious agent: norovirus

reservoirs: infected staff member, resident, or visitor

portal of exit: through vomit or feces from the infected person

mode of transmission: direct contact caused by not using proper hand hygiene or indirect contact from touching a contaminated surface

portal of entry: enters another person through mouth – contaminated hands, food or surfaces

susceptible host: another resident, staff member or another visitor

Hello Everyone,

Module 1 – Chain of Transmission Discussion Board Post:
Influenza in a Hospital
Infectious Agent: Influenza Virus – The flu virus, which causes fever, cough, sore throat, and body aches.
Reservoir: A staff member who had the flu but didn’t realize how sick they were and came to work anyway.
Portal of Exit: The virus left their body when they coughed, sneezed, or talked, sending tiny droplets into the air.
Mode of Transmission: The droplets landed on things like handrails, bed tables, or medical equipment. Other people touched those surfaces or breathed in the droplets.
Portal of Entry: A resident touched a surface with the virus on it, then rubbed their eyes, nose, or mouth, giving the virus a way into their body.
Susceptible Host: An elderly patient with health problems and a weaker immune system gets infected and becomes very sick from the flu.

Thanks,
Deborah

An example of Chain of transmission in my life in 2019 year:
Infectious Agent:Covid -19 virus

Reservoirs:I got that virus from my brother who was working in the hospital at that time.

Portals of Exit:I started having a cough and sneezing as well as fever.

Modes of Transmission:there were many modes of transmission as we were sharing the same basement.
Direct contact (touching, ),Indirect contact (contaminated surfaces in the kitchen or instruments),Droplet (sneezing, coughing),Airborne (dust or air particles)

Portals of Entry:I got these particles enter into my body through mouth, nose.

Susceptible Host:My grandfather (an elderly people) who was already having chronic illness , got infected and died because of that virus.

Hi Kiranjit,

Thank you for sharing your personal experience with the chain of transmission—it’s a clear and real example of how quickly diseases like COVID-19 can move between people in a household. You’ve explained each step well, from the virus to the person who gets sick.

[Deborah]

It is still unbelievable how fast Covid-19 spread. I am sorry to hear about your grandfather.
