Our annual summer Covid-19 wave continues to progress in the U.S., with wastewater testing and other early indicators pointing to slow-but-steady increases in disease spread. West Coast states, especially Hawaii and California, are reporting the greatest increases. Even with delayed and spotty data, we have enough information to signal this is a good time to…

Covid-19 metrics show continued signs that we’re at the start of a summer wave in the U.S., with the West Coast reporting more of a pronounced increase in transmission than other regions. Newer variants with the FLiRT mutations are contributing to this increase, but it will be a few more weeks before we understand their…

Wastewater surveillance and testing data suggest that the U.S. might be at the very beginning of a summer surge in Covid-19 cases, driven by a perpetual lack of collective safety measures and the newer variant KP.2. Without safety measures or long-lasting vaccines, the country faces a wave of reinfections every few months.

Covid-19 spread in the U.S. is still at a lull, following the trend we’ve observed since mid-March. In this era of the pandemic, though, low points in transmission still mean thousands of new infections every day. And the CDC just stopped tracking Covid-19 hospitalizations, removing one of our more reliable data sources as a new…

The U.S.’s lull between Covid-19 surges continues, with hospitalizations for the disease reaching their lowest value in over a year — though we’re about to lose that data source. As I’ve pointed out multiple times in recent weeks, there is still a lot of SARS-CoV-2 transmission going on even when CDC maps are colored all…
