What COVID measures work? It’s complicated

Scientists evaluate 7 different methods Michigan schools are using to prevent the spread of COVID-19.

Many schools in Michigan are requiring masks. Some are enforcing social distancing. Others have installed new ventilation systems. What none of them have is a concrete idea of what works to halt the spread of COVID-19.

Bridge Michigan evaluated seven different methods that schools in Michigan are using to control the coronavirus. It spoke to medical and public health professionals in order to find out what works and what doesn’t. And the truth is, it’s complicated.

The seven methods evaluated are:

  • Masks
  • Plexiglas separators
  • Ventilation upgrades
  • Social distancing
  • Surface sanitization
  • Hand sanitizer
  • Temperature checks

The key takeaway is that there is no one method that is perfect for preventing the spread of COVID-19. But several methods in combination can do a pretty good job.

Among the findings are that ventilation upgrades and mask mandates are helpful for limiting the spread of disease-carrying droplets. Meanwhile, temperature checks probably aren’t worth the effort.
