U.S. was slow to recognize coronavirus threat from Europe: CDC director 

The director of the U.S. Centers for Disease Control and Prevention (CDC), Robert Redfield, on Tuesday admitted for the first time that the U.S. was slow to recognize the coronavirus threat from Europe.

"The introduction from Europe happened before we realized what was happening" Redfield said in an interview with ABC News, noting that "by the time we realized the Europe threat and shut down travel to Europe, there was probably already two or three weeks of 60,000 people coming back every day from Europe."

As of Tuesday evening, the U.S. has reported more than 4.3 million COVID-19 cases and 149,235 deaths nationwide, according to the latest tally from Johns Hopkins University.
