While national averages for COVID-19 metrics appear to be at a peak or plateau as of mid-September, the picture actually looks pretty different from region to region.

The U.S.’s summer 2026 COVID-19 wave is in full swing. All disease tracking metrics report increased spread across the country, and the school year’s start and upcoming holiday weekend will cause further outbreaks. The Food & Drug Administration (FDA) has approved updated vaccines for this year, but they may be hard to access for many…

The latest data are from before Thanksgiving, and the increases are likely to continue as outbreaks from holiday travel and gatherings show up in our numbers.

After an uncertain few weeks, all available metrics now agree that the U.S. has passed the peak of its summer/early fall COVID-19 surge. But even as disease levels trend down, there is still a lot of SARS-CoV-2 going around, and levels are unlikely to drop too much further as we start getting into colder weather.…

The latest COVID-19 data offer conflicting information about whether or not we’ve passed the peak of this year’s summer/early fall surge.
