Coronavirus: Close the bars. Reopen the schools. - Vox - 0 views

Reopening is a community-wide project. Whether a school can reopen safely, for example, doesn’t just depend on capacity, personal protective equipment, or individual actions. It depends on how widespread the coronavirus is in the community outside the school’s walls.

But if a community is flooded with infections, the chances are much higher that those infections will creep in no matter how many protective steps are embraced.

If you want to reopen schools this fall, then you need to get the spread of Covid-19 down, as close to zero as possible, this summer. And that means opting not to reopen — possibly at all and definitely not at full capacity — restaurants, bars, nightclubs, or other places that will lead to significantly more coronavirus spread but have less value to society than schools.

The goal is to keep the basic reproduction number in a community below 1. That would mean that every person who gets coronavirus transmits it to, on average, fewer than one other person. Over time, that would lead to coronavirus cases falling closer and closer to zero. This number is typically calculated as the R0 or Rt, depending on the methods used. (Some websites, like Rt.live, calculate this figure for all states, and it’s at 1 or more in most states.)

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.
