Just plugged today's CDC numbers into my new forecasting model (releases Mon). My initial reaction was "Jesus Christ. That's bad. That's really really bad."

If you live in the West in particular, it's currently about as bad as last winter. About 1 in 23 infectious out West. CDC regional COVID-19 transmission graph. The West region is nearly identical to last winter's peak.
Those of us modeling have been talking about the late-summer wave -- all year -- as a given.

The 1-day isolation policy, the lack of a twice-annual updated vax, & the vilification of masks are emblematic of #LaissezFairePublicHealth. A wintery summer surge is the result.
I hope the present numbers are revised downward, but there is no reason to suspect that. In my view, the current estimates are as likely to be overestimates as underestimates.
Here's the updated CDC COVID "heat" map released today, recolored with dark red to equal more transmission. Highest transmission: West coast, Utah, Wyoming, Minnesota, Oklahoma, Texas, Louisiana, Arkansas, Florida, Carolinas

We're in the 6th year. See the small red line, bottom left. Notice how closely it tracks the median (gray), year 4 (yellow), & year 5 (orange).

Acknowledging caveats, those are plausible gist-level scenarios for months ahead. year over year graph, summarized in post
🧵3 of 8 | PMC Dashboard, April 21, 2025 (U.S.)

Expect steady transmission bouncing up and down around the current national lull-level estimate the next several weeks. 200-350k daily infections nationally.

This is about as low as lulls bottom out anymore. Past 12 months and forecast, summarized in post

Year-over-year transmission (red line, lower left) is tracking the median (grey), year 4 (yellow), and year 5 (orange) closely.

If that trend continues, expect steady yet bumpy transmission the next couple months, until June/July.line graphs, described in tweet

The heat map shows only 4 states in the CDC 'high' level and none in the 'very' high level.

Check local data. Those timing activities to lulls may see a clear opportunity.heat map, described in tweet

The NIH Clinical Center drops universal masking after 5 months of protecting patients, family, & staff.

Wastewater-derived estimates indicate 2.79 million Americans are getting Covid per week AND top actuaries suggest an American dies of Covid every 3 minutes.

🧵1/5 Masks are optional beginning April 11. Staff will mask on request.
These are the current wastewater-derived estimates of transmission.

2.79 million Covid infections/week in the U.S. in the current high "lull."

2) Watch this video to understand how we use excess death data from one of the world's largest reinsurers to estimate how this week's infections will result in >1,000 deaths.
3) Transmission is steady or declining across much of the nation, but remains high in 11 states and DC, per the CDC.

Other sources, such as WastewaterSCAN, show a near doubling of transmission in the Northeast the past few weeks, so remain cautious.

The transmission forecast suggests 300-500k daily infections the next month. If the data get retroactively corrected downward, we could dip to 200k.

PMC Update on #ExcessDeaths

🔥109,000-175,000 people in the U.S. are expected to die as a result of COVID in 2025, based on estimates derived from Swiss Re
🔥COVID deaths expected to be on par with lung cancer in the U.S. in 2025
🔥Death data added to the dashboard
2) Full video links to learn more about COVID #ExcessDeaths in the U.S.

Dashboard page (presently featured): pmc19.com/data
Downloadable file: pmc19.com/data/deaths033…
Veed platform: veed.io/view/558039f4-…
3) The new #ExcessDeath statistics build on what we described in the 5-year pandemic anniversary video.

Watch from 12:14-20:00 to see how simplistic models underestimate COVID deaths. The Swiss Re model solves that problem. PMC extends that work.
