It's not COVID we need to worry about from international visitors but the FLU's and RSV's that we haven't been exposed to for 2 years. It's going to be total carnage if they get loose. Isolation would slow this down and in many cases prevent it.
people wash their hands more, sanitize and use face masks, along with social distancing. they all still work for those virus's you mentioned.
what are the stats looking like overseas for those virus's? unless there is been a major increase somewhere why would not open up?
