An estimated 1 in 81 people are actively infectious during the ongoing 11th wave.
The "shutdown" has created a blackout at the state level.
Transmission is half that of the peak one month ago, and we anticipate a relative national "lull" in early-to-mid November, albeit still at dangerous levels.
Our model uses a combination of CDC and Biobot data, so we are able to estimate national statistics despite the CDC data going offline. On the map, note that Puerto Rico continues to update; they use a CDC-style system but were dropped by the CDC long ago. For full methodology, review the technical appendix on the website.

#DuringCOVID is today. We estimate >600,000 new daily infections. This is about half the peak on September 6.
Notice current levels are similar to the estimated peaks of the first 3 waves.

Weekly estimates:
🔹4.5 million infections

Current estimates have closely tracked those of 2023. However, as we forecasted, they are starting to dip a bit lower.
Notice the relative national "lull" generally in early November.

We forecast dipping below 500,000 new daily infections in a couple weeks. These estimates are volatile without the CDC data.

There are no state-level updates this week. You may find last week's estimates helpful. In general, transmission is about 25% lower, but it's hard to know how much lower (or higher) in each state.

3 state pharmacy boards are continuing to block access to boosters unless one has a prescription (& "high-risk" condition).
Please contact them to complain. Help keep our Louisiana-based team safer. 🙏
The PMC website includes an international directory of websites with COVlD wastewater monitoring. It is more up to date than the directories of the EU and WHO.
Let's review what's happening in Europe...

Data in #Austria show a rising COVlD wave. The x axis (bottom) has infrequent labels, but the data shown go through October 8th.
Key points in my letter to the pharmacy boards. 🧵1/7
Georgia law indicates that the pharmacy board is to follow ACIP. They do not dictate further nuance. Georgia continues to require prescriptions, going against the spirit of the law, ACIP, and 47 other states.
🧵2/7
Louisiana law tells the pharmacy board to follow ACIP. ACIP says do not require a prescription, and 47 other states agree.
The Louisiana pharmacy board continues to require a prescription.
On the back end of this unprecedented 11th wave, "times they are a-changin." In particular, COVlD levels are shifting north and east.
Notice that few states are in the highest and lowest categories. Much of the south and west have considerable transmission post-peak. Many places in the north and east are seeing steady or increasing transmission after relatively lower levels.
Overall, levels are lower than the past few weeks, but transmission remains considerable. Those relying on anecdata (friends, coworkers, and family infected) may increasingly realize we are in a wave.
We estimate nearly 750,000 new daily infections nationwide, meaning approximately 1 in 66 people or 1.5% are actively infectious.
These estimates are derived by linking wastewater levels to IHME true case estimates using methodology commonly employed worldwide, detailed on the website, noted in a pre-print. Many publications in leading medical journals link wastewater data to key metrics that matter, noted in the online technical appendix.
In this week's report, we note adding North Dakota and Puerto Rico to the heat map in support of health equity. We have been imputing ND levels since the launch of PMC 3.0 using data from neighboring states. PR continues to report qualitative levels using the CDC format but is not longer included on the CDC website.

PMC COVlD Update, Sep 29, 2025 (U.S.)
State-level prevalence estimates, AL to MS. The levels use CDC labels, which tend to have an optimistic portrayal of risk. For example, CO is listed at "low" (by our estimate 1.5% infectious).
#MaskUp at 1.5% if having lapsed.

PMC COVlD Update, Sep 29, 2025 (U.S.)
State-level prevalence estimates, Missouri to Wyoming.
New York had *huge* retroactive upward corrections, and is now "High," as many residents hypothesized.
Note, Puerto Rico only provides CDC qualitative levels, so no data.
The CDC reports 29 states & DC are experiencing High or Very High transmission.
The heat map is a patchwork quilt with COVlD levels varying considerably state by state.
Transmission is shifting north + east.

PMC COVlD Dashboard, Sep 22, 2025 (U.S.)
COVlD levels by state, AL to MS.
Note that even levels the CDC calls "Low" like Guam at 1.5% actively infectious are at the threshold where I would tell people who have lapsed that it's time to #MaskUp.

New York is a good example of where the CDC label of "Moderate" simply does not cut it. 1 in 49 is very high, and the data quality statewide has been poor.
