Finally some sanity from CDC. Early on there's evidence that people got infected but they didn't know it, yet they can infect others. The only logical conclusion is everyone should wear mask. See the Asian countries that are doing that got the virus pretty well controlled. I was surprised CDC didn't err on the safe side. You don't need to recommend everyone wear N95. Surgical face masks or homemade masks works too.
