Keeping schools closed comes with massive, long-term individual and societal costs. Many children cannot effectively learn, grow, engage, socialize, be active, eat healthy food, or get support until schools reopen. Parents and caregivers cannot go back to work until children go back to school. Knowing that schools will reopen at some point, we set out to answer this question: What strategies should schools consider to reduce risk of COVID-19 transmission?
Note that a risk reduction strategy is different from a goal of achieving zero cases. There is no such thing as “zero risk,” in anything we do, and certainly not during a pandemic.
