Yes, I think what we're seeing in the news right now—talking about banning Indian and Pakistani flights—is the right thing to do. I think it should be very country-specific. Yes, we should do it. We should limit our ports, depending on the locations of highest infection. We should be aggressive at limiting who comes in so that we can manage both community spread as well as foreign-introduced spread.
Should we have done it earlier? Yes. I think everyone agrees with that. I think if everyone had to rewind and say they were worried about variants of concern a year ago, they probably would have done it. That's why I'm saying we should not just be worried about the variants now but should also be worried about the new strains that might develop.
Let's forget about what we did badly before. Let's be aggressive now and start hammering down on those countermeasures.
