Former federal regulator Scott Gottlieb said Monday that new COVID-19 case increases due to the delta variant in the United States will reach a peak in the next few weeks, using the downward trend in new infections in the United Kingdom as a reference.

“If the U.K. is turning the corner, it’s a pretty good indication that maybe we’re further into this than we think and maybe we’re two or three weeks away from starting to see our own plateau here in the United States,” said Gottlieb, the Food and Drug Administration commissioner under former President Donald Trump.
