1) 5-yr Anniversary of the WHO Pandemic Declaration

🔥10 waves
🔥Covid mortality rivals lung cancer
🔥8 infections/person by 2030
🔥Long Covid as catastrophic
🔥Death trajectories becoming complex
🔥"During Covid" as anti-science rhetoric
🔥Serious ppl take Covid seriously
🧵
2) Wastewater-derived estimates of case rates show international consensus 20-26% of populations got Covid during the peak 2 months of the 2023-24 winter wave in the U.S., Canada, and the U.K.
3) The ratio of reported cases versus true cases has remained consistent, demonstrating the validity of wastewater-derived estimates. True cases are 15-30x reported cases, a consistent ratio. There are no examples demonstrating low case rates.
4) Misinformation is based on cognitive biases that steer people toward easy-but-bad data or lead them to overestimate their skills.

Disinformation can be blatant or grounded in specious pseudo-scientific arguments. Financial COIs are often the cause. Misinformation: Wastewater can’t predict cases  You can’t do that  “Streetlight effect,” “drunkard’s search,” or “McNamara fallacy”  “Dunning-Kruger fallacy”  Usually people w/expertise in adjacent or unrelated fields, or with clinical non-scientist backgrounds   Disinformation: Audacious lies: herd immunity, masks, tests, vaccines, air cleaning, surveillance Specious arguments: Whataboutism, amplifying trivial limitations, misrepresenting the CDC  Often serious Social/ Online Subscription & Ad Dollar Conflicts of Interest (SO SAD COIs)
5) Contrary to misinformation and disinformation, wastewater-derived estimates have a long history of publication on top scientific journals Example articles
6) The NYTimes shows that Covid continues to cause excess deaths, meaning it is killing hundreds of thousands of Americans in 2025.

Their estimates are overly simplistic but make the correct argument. See next few. NYT graph of excess deaths. Simple
7) More complex analyses of Covid excess deaths remain much too simplistic and often underestimate current Covid deaths. They do not account for "mortality displacement" -- the idea that so many have already died, we should be seeing fewer deaths by now. We're not. Our World in Data perpetuates bad Covid analyses that minimize Covid
8) Actuaries measure excess death correctly (or still slightly underestimate). They find Covid deaths are on par with lung cancer in 2025. Current excess death estimates using the best formulas show that under the "pessimistic" scenarios (similar to reality, if not lightly optimistic) Covid deaths are slightly higher than for lung cancer
9) The sources of Covid excess deaths are increasingly understood and paint a more pessimistic long-term trajectory, as demonstrated by (multi-systemic) non-respiratory deaths. Multi-systemic deaths on the rise, consistent with or surpassing more pessimistic scenarios.
10) The past and ongoing consequences of Covid will be marked by health disparities. Race, ethnicity, socioeconomic status, immigration status, LGBTQ. JAMA NO article on c19 disparities.
11) We are headed from nearly 4 Covid infections on average to 8 cumulative infections over the next 5 years if current trends hold. The Long Covid burden will be substantial.

Mitigating risk using multi-layered mitigation, like during the early pandemic, helps greatly. Line graph summarized in post
12) Nearly 5 million American adults have become disabled during the pandemic, with an ongoing linear trend because cumulative infections remain an ongoing burden.

We're doing almost nothing as a society to reduce infections. NYT graph
13) Children continue to become sick more frequently and more severely, with an increasing proportion missing multiple weeks of school.

So-called "lockdowns" don't case this. An annual Covid infection is the likely culprit. NYT graph
14) Younger adults are becoming disabled by Covid, though often still working. Women are particularly burdened. >1 million female workers <65 have become disabled during the pandemic
15) Though at a slower clip, male workers <65 years old are also becoming disabled by Covid.

>1 million female workers <65 have become disabled during the pandemic >0.5 million male workers <65 have become disabled during the pandemic
16) Older adults are dropping out of the workforce. 2.0-2.7 million so far, so-called "excess retirements" graph summarized in post
17) Covid deaths are less and less about acute deaths and more and more about complex non-acute death trajectories. Graphs of 4 prototypical death trajectories.
18) An example of a Covid cumulative reinfection death trajectory. Complex death trajectory, stairstep decline with c19 infections, with superimposed organ damage.
19) I have no idea what people mean by "during Covid" - a useless and anti-science concept. "During Covid" as the early pandemic
20) #DuringThePandemic is today. 10 covid waves, each labeled during the pandemic
21) #DuringCovid is today. 10 covid waves, each labeled as during covid
22) "During Covid" is anti-science offensive nonsense.

We don't say during car accidents, during lung cancer, or during diabetes to describe the onset or any time point of these public health problems. graphs of covid, car accidents, lung cancer, and diabetes, with "during" labels for the onsets
23) Many people are "high risk," simply based on known evidence, albeit imperfect. Many more are high risk based on unknown or undiagnosed factors. Most should assume a high risk family member or that high risk themselves. Estimated >50 million Americans with known high risk
24) NIH has required universal masking in 48 clinical centers for >4 months because they lead on healthcare. info from nih website
25) Over 75% of PMC Covid Dashboard viewers note using 4 layers of mitigation (masks, vax, tests, air quality) in the past 6 months. 95% use at least 3 out of 4 layers. described in post

PMC COVlD Update, Apr 13, 2026

Levels are flat during a relative "lull" in transmission.
▪️1 in 187 estimated actively infectious
▪️260,000 estimated new daily infections
▪️High: OK, MS, WV
▪️Moderate: VT
▪️All other states low/very low in relative transmission

🧵THREAD 1/6 Heat map from CDC data and PMC prevalence estimates harmonizing CDC and Biobot wastewater data with IHME true case estimates to derive ongoing transmission projections
COVID-19 persists in 2026.

We are in a relative "lull" following a 12th wave, but at a baseline of 200-300K estimated new daily infections.

Transmission was lower in the era many refer to as #DuringCOVID, when multi-layered mitigation was used instead of denial.

🧵THREAD 2/6 Annotated graph of the 12 waves (U.S.)
Transmission during a "lull" is high in an absolute sense. Many people are getting infected.

Simultaneously, its low in a relative sense, or compared to so-called "typical" transmission. In most places, it's a safer time for medical/dental care.

PMC COVlD Update, April 6, 2026

Transmission is stable in a relative "lull" nationally between waves.

We estimate that approximately 313,000 people are still getting infected per day, with outbreaks radiating from TN and MS.

With limited data reported, Mississippi has an estimated 1 in 27 residents actively infectious.

In a room of 25 people, that's a 61% chance of exposure, if no testing/isolation protocols.

This is an unethically misleading study with findings easily explained by residual confounding. Some health systems and patients have thorough record keeping. Others don't. All sorts of variables will correlate (infections, cancers, anything else tracked in medical records).
This is a really obvious issue for an international epi study. It should not have been published.
The above study is using the same processes the anti-vaxxers use -- junk epi that does not account for confounding -- to support whatever pre-conceived notions the authors have, with absurdly large effects.

PMC #COVID Update, March 23, 2026 (U.S.)

Transmission levels have plummeted nationally as we shift from the 12th wave toward a relative "lull."

Over half the states have "Very Low" relative transmission, per the CDC.

🧵THREAD 1 of 8 Heat map using CDC levels and PMC estimate of prevalence (1 in 147 actively infectious nationwide).
Transmission varies considerably by state.

Highest
🔥Mississippi: 1 in 31 estimated actively infectious
🔥Michigan: 1 in 41
*Both states w/limited data though

Rates are quite low in relative terms in California, AZ, FL, HI, ID, MA, NV, NY, OR, RI, UT, WI

The 6th anniversary of the WHO's pandemic declaration was March 11.

Bots, minimizers, & individuals' psychological defense mechanisms will downplay that.

Yet, the U.S. just had a 12th wave. We estimate >5 cumulative infections/person & ongoing health harms.

As of today, the COVID-19 pandemic is now longer than WWII.
If you have been living in denial the past 6 years, know that the U.S. is winding down from a 12th wave of infections presently.
Denial is but one of several obvious defense mechanisms people use to try to block their awareness of the ongoing toll of COVID-19. There are many others.

Short-term capital also plays a role, but even that requires a large dose of defense mechanisms.

During this 12th COVlD wave, the CDC reports 1-in-3 states have "High" or "Very High" levels.

PMC estimates the proportion of residents actively infectious (prevalence):
◾️USA: 1 in 67
◾️IA: 1 in 27
◾️MI: 1 in 25
◾️IN & CT: 1 in 23
◾️ME: 1 in 21
◾️OK & SD: 1 in 17

🧵1/ Heat map using CDC data. National PMC prevalence estimate noted; estimated incidence of 732,000 new daily infections.
On average, Americans have have 5.0 cumulative SARS-CoV-2 infections.

This week's infections are expected to result in 1/4 to 1 million new #LongCOVID conditions and ≈2,000 excess deaths.

The wave peak is now estimated >10% higher than last week at 1.2 million new daily infections, nearly double the Delta wave.

We expect sustained high transmission (≈600,000 to 750,000 new daily infections) the next few weeks as COVlD circulates through schools/families.
