coronavirus pandemic are engrained in our minds.But with “pandemic fatigue” an increasing concern, public health experts are reminding people of the importance of these measures using an unusual metaphor — cheese.The “Swiss Cheese Model” uses slices of cheese to visualize how interventions work together.
Each intervention — including physical distancing, mask-wearing, hand washing and disinfecting — is depicted as an imperfect barrier to virus transmission by the holes in the cheese.When multiple effective, but imperfect, interventions are combined like a stack of Swiss cheese slices, some of the holes in the cheese are covered and virus transmission is decreased or even stopped.
