Bar chart titled, “Published Sequences from NS3, CDC Sequencing Contracts, and Other CDC Sequencing Efforts: Weekly Published Sequences.” The X axis represents time, from January 2021 to May 2025, while the Y axis represents SARS-CoV-2 sequences published each week. The number of sequences published increased and decreased along with COVID-19 spread from 2021 through 2023…

National COVID-19 metrics in the U.S. continue to report consistent disease levels across much of the country — as I noted last week, I remain pleasantly surprised that we haven’t seen a sharper uptick yet this summer. Still, there are signs of increased SARS-CoV-2 spread in wastewater in some places, particularly on the West Coast…

While there are signs of a summer COVID-19 wave on the horizon in the U.S., disease levels remain low to moderate across much of the country as of early June. I’m honestly surprised by the latest data — I expected more of a sharp increase by now. But the new variant NB.1.8.1, now spreading in…

Advocates pushed back against threatened funding cuts and won continued support for Long COVID work in the Minnesota legislature’s final 2026–27 budget.

A summer COVID-19 surge is likely on the way in the U.S. While the disease is still spreading at more moderate levels in most of the country, there are signals of increased viral spread in parts of the West and East Coasts. New variants are likely to accelerate outbreaks from summer travel and gatherings. And…

Everyone in the COVID-tracking space is watching for a summer surge. Disease levels in the U.S. remain on the lower end as of late May, but I see warning signs for potential increases soon: cases are going up in some West Coast states, and new variant NB.1.8.1 has reached the U.S.

While national COVID-19 metrics continue to report slight declines, multiple weeks of increased spread in some parts of the U.S. (particularly on the West Coast) suggest we are getting closer to a summer wave. Plus, the latest available data are from before Memorial Day weekend, which tends to be the start of summer travel and…

The U.S. remains in a moderate lull between COVID-19 surges, with national metrics reporting slow declines through mid-May. There are increases in disease spread in a few West Coast states, however, and new variants now arriving in the country are likely to spur outbreaks this summer. Also, Novavax’s COVID-19 vaccine is finally approved — but…

National COVID-19 metrics continue to report declines, as the U.S. remains in a moderate lull between winter and summer surges. There are signs of increased disease spread on the West Coast, indicating that this region may experience the start of a summer wave before others.

In August, leading Long COVID researchers will gather in Santa Fe, New Mexico for a major conference on Long COVID and other post-acute infection syndromes. The meeting, organized by Long COVID experts and hosted by the nonprofit Keystone Symposia, follows a similar conference in 2023 at which scientists presented novel, exciting studies.
