Masks work! Amazing study of 26 elementary schools that pulled wastewater samples every 15 minutes. Researchers observed the masked percentage in the school. “The odds of a positive wastewater signal in the 5 days after one of these observations decreased by 47% for each 10% increase in the proportion of people who were fully masked."

“It doesn't have to be all or nothing. Even a little nudge can keep kids safer at school.”
