Joe Biden on the coronavirus pandemic:

"If [Trump] had shut it down a month earlier, we'd have probably another 45-60 thousand people alive instead of dead... He didn't listen to guys like me back in January saying 'we have a problem'"

After President Trump implemented his travel ban from China on January 31, Joe Biden said in Iowa "this is no time for Donald Trump's record of hysterical xenophobia and fear-mongering."

Joe Biden said on March 12:

"Banning all travel from Europe or any other part of the world may slow it but as we've seen, it will not stop it. Travel restrictions based on favoritism and politics rather than risk will be counterproductive."

Joe Biden also wrote in a USA Today op-ed on January 27 that travel bans during the ebola epidemic would have been "reactionary" and "would have made things worse"
