Our new pre-print shows that people are excited to use N95s during COVID surges when given them for free w/helpful information on their evidence & how to use them. 1/ psyarxiv.com/f76vw
You might remember when we posted about the study back in December!
I hope you find the results useful. We tried to make the figures relatable, even if you're not reading science articles every day. Please let me know if you have questions! 2/
We gave out 2,500 #N95 masks in 5 packs to our racially & socioeconomically diverse community. Many used N95s for the 1st time. People treated us like we were giving them kidneys. So grateful!
97% used at least 1 N95 & 40% used all 5 within 1-mo!

We called our #N95 giveaway study "Project #Bandura," named for the famous #psychologist who studied social learning.
Well -- people learned, socially! >80% of participants told others about N95s. Several enthusiasts shared w/dozens of ppl! 4/
Cost was the biggest barrier to sustained #N95 use!
Still, ppl planned to buy an average of >10 more N95s in the near future (2x what we gave them).
More interesting, if FREE, 88% would use N95s again. Once you pop, you can't stop! 5/
We only gave away 2,500 N95s. It was labor intensive b/c we included educational materials, had a follow-up survey, went through IRB, etc.
However, it validates @amandalhu's 17,000 mask giveaway, those of cities and fed govt's.
As a #psychologist, there is 1 big truth I believe w/my heart. If you talk to most ppl in a way that's reasonable, about 97% will feel empowered to take actions to improve their lives & communities.
As true for COVID as anything else. We just need more courageous leadership. 7/
With N95s extremely popular during #COVID surges, what's the national strategy?
The U.S. had a stockpile and started giving them out for free (after my psychology research team 🤣). There are no known plans to buy and distribute more.
Transmission typically accelerates in mid-November.
We are currently in a relative 'lull.' We estimate about a quarter-million new daily infections with 1 in 185 people actively infectious. Still bad, likely to get worse.

PMC COVlD Update, Oct 27, 2025 (US)
Our forecast through November 8 calls for flat transmission.
Nothing yet indicates the onset of a winter wave, but it would also be atypical for the lull to last much longer than another 2-3 weeks.
2/9 🧵
PMC COVlD Update, Oct 27, 2025 (US)
We estimate 264,000 new daily infections during this 'lull' period.
Biobot data have returned. Our substitute data from WWS last week correlated r=.97 (near perfect) with that, but Biobot did retroactively increase recent estimates.
SARS-CoV-2 transmission has fallen.
🔹1 in 191 (0.5%) actively infectious
🔹"Lull" levels at 20% of the summer peak
🔹255,000 new daily infections (still concerning)
Many will knock out higher-risk activities the next 2-4 weeks.
🧵1/11
PMC COVlD Update, Oct 20, 2025 (U.S.)
"Lull" transmission remains dangerous:
🔹1.8 million estimated new weekly infections
🔹>90,000 estimated new #LongCOVID conditions from this week's infections
🔹>500 excess deaths to result from this week's infections
🧵2/11
PMC COVlD Update, Oct 20, 2025 (U.S.)
Exposure risk during "lull" transmission remains high when engaging in many social interactions.
Interacting with 25 people yields a 12% chance of exposure. 100 people? 41% chance of exposure, assuming no testing/isolation.
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.
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.

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.
