Does the US approach mean countries like New Zealand need to stay isolated until a vaccine is found? Or would herd immunity eventually eradicate the virus in US?
They should definitely have anyone abroad strictly quarantine for at least 14 days upon entering the country. Herd immunity would slow it to a crawl but it seems like it could pop back up in odd pockets of previously unexposed people. We also still don't know how long immunity will last- scientists are hopeful that it will last until a vaccine is produced but that's not a guarantee.
