Longer answer, what I predict he will do:
--Biden can't mandate face masks everywhere in the country, since the President doesn't have that power, but he can at least set an example by doing so himself frequently in public and verbally encouraging it.
--We can expect Biden won't be constantly warring with the CDC & Fauci, deflecting blame to scientists, to China, to state governors, etc etc. Biden definitely has a "we're all in this together" attitude.
--Biden will actually retain Fauci unlike Trump who threatened to fire him after the election.
--Biden won't be touting miracle cures like sunlight and disinfectant and hydroxychloroquine and Regeneron before they are proven & accepted by the medical community.
--We can expect Biden & the incoming congress will pass another Covid-related stimulus if one doesn't pass by then
Those are the basics I think
