It's HOT COVID SUMMER in the Deep South. No geographic/political prejudices, see next.
Covid is burning through Guam, Louisiana, Florida, and Texas (underestimate due to sites down).

It's also HOT COVID SUMMER out West. No geographic/political prejudices, see previous.
California and Hawai'i have unrelenting transmission.

New York State is mostly in the dark on COVID transmission. The CDC has most sites offline. The NYS dashboard includes the most recent estimates. It was getting bad in NYC before lights out.
Texas has fallen from High to Moderate, but it appears to be an artifact with many sites going offline this week.
High transmission sites going offline adds noise to the forecast. Uncertain times.

Today you experienced a typical day in the last 5.5 years of the pandemic, with transmission higher than 47% of days, and lower than 53%.
Typical means that in a room of 35 people, there's a 1 in 4 chance of exposure.

The year-over-year graph shows that current transmission (red line) is similar to that of 2 years ago (yellow line) and 4 years ago (blue line).
The forecast formally models year-over-year trends and recent transmission. We are estimated to soon reach 500,000 daily infections, but with low real-time data quality, regional variation, and much uncertainty.

Spain offers an illustrative example of uncertainty ahead. Wastewater data are limited to sites (albeit many) in the Barcelona area and reported monthly. XFG took off with limited warning.
The U.S. sites have much better representation and report more frequently so can spot a surge with greater warning.
Note: The variant-naming system (XFG) is not community-centered. It's jargon. Even the nickname, "stratus," is unhelpful jargon. For communities dealing with this jargon, we recommend the following memory tip:
XFG = X-FG, X-FoG, or eXtra brain FoG.
Each reinfection increases the cumulative chances of brain fog and other neurologic, vascular, and multisystemic damage. x.com/michael_hoerge…

It's a good time to stock up on masks and tests. WellBefore is my go-to brand for disposable kids' masks. I've made 2 major purchase orders the past month to donate to local kids.
I receive no preferential discounts, kickbacks, or other financial benefit from any company, including in the COVID space. I talk to many company leaders regularly and worked out the 10% discount.
Let me know if the discount code works or if you need any help with sizing.

Serious people continue to take COVID very seriously. We distributed 1,000 tests in 90 minutes today.
Serious folks mask, vax, test, and clean the air. Top health systems require universal masking.

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

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
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.
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.
🧵1 of 10 (don't miss #10)!
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.
🧵2 of 10
1 in 24 people in Tennessee are estimated to be actively infectious with SARS-CoV-2. That's a 65% chance of exposure in a room of 25 people where nobody is testing/isolating.
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.
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

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.
🧵2/
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.
