As experts panic about the risk posed by the Delta variant, LA County's infamous Public Health Director Dr. Barbara Ferrer last night decided to revive LA's indoor-mask policy, requiring all individuals - including the vaccinated - to wear masks at gyms, restaurants, bars, supermarkets and - importantly - schools.

Setting aside the issue of whether the Delta variant poses a serious threat to the public health of California (available evidence would suggest that it doesn't), the CDC released guidelines earlier this month for schools across the US for deciding how to handle COVID prevention policies including masking.

The Feds said that while vaccinated teachers and vaccinated students be allowed to go mask-less, the unvaccinated should be required to wear masks. It also recommended that schools track the vaccination status of their employees and students.
