Teachers union prez to CDC: We’re not convinced that your new three-foot distancing rule for schools is based on science

The grand irony of this complaint is that the six-foot rule that the union prefers & wasn t based on science. Two days ago, former FDA chief Scott Gottlieb took the CDC to task for having relied so heavily on six feet as the baseline for social distancing since the start of the pandemic when there s never been any hard data to support that. Gottlieb can t even track the rule s provenance. His best guess is that the CDC turned to it as a rule of thumb on safe distancing in the early days of COVID when it thought the virus was mainly spread via large droplets, which turned out not to be true. The virus spreads via aerosols, which can linger in the air and travel much further than six feet. So why didn t we discard the rule long ago? The agency & doesn t always identify the underlying science of its recommendations, Gottlieb lamented. We don t know the exact basis for its initial view to stay 6 feet apart.
