The U.S. has tragically surpassed 400,000 COVID-19 deaths, and case numbers and hospitalizations are likewise spiking to record levels around the world. With vaccines now rolling out out, there is reason to hope that there is an end in sight. However, by most estimates, widespread vaccinations will not be in place until the middle of the year at the earliest. So, we have some ways to go yet with social distancing, mask wearing and other pandemic mitigation behaviors.

It is worrying, therefore, that the world is witnessing a consistent decline in compliance with these mitigation behaviors over time. For example, a Gallup poll from the fall that tracked social distancing habits among Americans found that the percentage of respondents avoiding small gatherings declined by 40 points since April, while those avoiding public places declined by 25 points. Public health experts term this phenomenon “pandemic fatigue” and cite it as a contributor to the increase in incidence rates being witnessed here and in Europe.
