schools likely carry some risk of Covid-19 transmission, as an indoor environment in which students, teachers, and other school staff interact for hours. But schools are also really important for day-to-day life — not just for kids’ education, but also for food, shelter, and child care while parents are at work. Knowing that, a community may decide to fit schools into its reopening budget. The trade-off would be that other places, such as restaurants, bars, or gyms, more likely have to remain closed.
