The United States should prepare for a possible summer increase in Covid-19 cases across southern states, former White House Coronavirus Response Task Force coordinator Dr. Deborah Birx to CBS Sunday morning.
It is now predictable that the south will see increases in the summer, and northern states will see increases in the winter – especially around holidays, Birx said.
Birx said she is closely following data from South Africa, which has recently seen an increase in new Covid-19 cases.
“Each of these increases is about four to six months apart. It tells me that the natural immunity decreases enough in the general population after four to six months – that there will be a significant increase again,” Birx told “Face the Nation.”
“That is what we need to be prepared for in this country. We should be preparing right now for a potential increase this summer over the southern United States because we saw it in 2020 and we saw it in 2021. ”
Public health officials need to make it clear to the public that protection against the infection diminishes over time, and precautions should be taken against vulnerable or compromised people, Birx said.
She said Covid-19 home test kits and boostershots are critical tools to help Americans deal with increases.
