Mitigation Strategies
- Image source via the New York Times ” The Swiss Cheese Model of Pandemic Defense“
James Reason , an english researcher, proposed the image of “Swiss cheese” to explain the occurrence of system failures.
According to this metaphor, in a complex system, hazards are prevented from causing human losses by a series of barriers.
Each barrier has unintended weaknesses, or holes – hence the similarity with Swiss cheese. Applied to COVID, we ought to think of multiple layers as part of our strategy.
⚠️ The central theme is to apply multiple mitigation layers in unison and not in isolation.

How many mitigation layers are being implemented in your school or place of business ?
This a reasonable question to ask your school head or employer ?
⚠️ 2021 transmission risk cannot be effectively managed with only 2020 strategies or solutions.
