The Pennsylvania Supreme Court has given school districts the authority to decide whether children need to wear masks in schools. Even though they have the power to revoke mask mandates, now isn’t the time to use that power. With cases of COVID-19 spiking, some area school districts aren’t requiring students to wear masks. The Northern Lehigh and Whitehall-Coplay school districts are among the districts that made masks optional when students returned from winter break. It’s easy for the highly contagious disease to spread where lots of people gather indoors in places such as schools. Once the disease starts spreading throughout the student body, you’ve already missed your opportunity to slow it down with a mask mandate. Children with COVID then take the disease home and spread it to their families and their at-risk relatives, and the disease gets that much harder to contain. We urge all school districts to mandate the wearing of masks until the rate of transmission of COVID drops to a safer level.
