The US should prepare for a possible summer surge of Covid-19 cases across Southern states, former White House Coronavirus Response Task Force coordinator Dr. Deborah Birx told CBS on Sunday morning.
It’s now predictable that the South will see surges in the summer and Northern states will see surges in the winter — especially around the holidays, Birx said. Birx said she closely follows data out of South Africa, which has recently seen a rise in new Covid-19 cases.
“Each of these surges are about four to six months apart. That tells me that natural immunity wanes enough in the general population after four to six months — that a significant surge is going to occur again,” Birx told “Face the Nation.”
