Kinda useless as people can fly to Mexico sneak in thru San Diego. I can't believe in 2020 we still don't have a simple and effective reusable respirator, which evaporates all aerosols and turns them into safe to breathe vapors. I also think the ban now is good, but 30 days will not be enough as things are exponentially getting worse. Even if we reach the infliction point, this is not gonna end in 30, 60, or even 90 days.
