It's weird you said for "enacted similar purposes". I've looked at two articles from the date of Jan 31, 2020 (as Biden's tweet from 2/1/2020 says he did it yesterday). Interestingly, neither one mention the ban being because of Coronavirus. Which of course makes sense because that was before 'rona blew up.
So they didn't actually ban for similar purposes, like you said. Trump didn't do his ban to stop the spread of coronavirus.
Here's politico, no mention of coronavirus as the reason for the ban:

Nope. Not corona.
So many conservative lies in this forum.
