As a clinical health psychologist, I notice that many people are using psychological defense mechanisms to downplay the risk of COVID.

These are my Top 7 examples:

🧵 Top 7 Psychological Defense Mechanisms Used to Downplay COVID
#1 – Denial – Pretending a problem does not exist to provide artificial relief from anxiety.

Examples:

“During COVID” or “During the pandemic” (past tense)

“The pandemic is over”

“Covid is mild”

“It’s gotten milder”

“Covid is now like a cold or the flu”

“Masks don’t work anyway”

“Covid is NOT airborne”

“Pandemic of the unvaccinated”

“Schools are safe”

“Children don’t transmit COVID”

“Covid is mild in young people”

“Summer flu”

“I’m sick but it’s not Covid”

Taking a rapid test only once

Using self-reported case estimates (25x underestimate) rather than wastewater-derived case estimation

Using hospitalization capacity estimates to enact public health precautions (lagging indicator)

Citing mortality estimates rather than excess mortality estimates. Citing excess mortality without adjusting for survivorship bias.This is from a psychology book by Nancy McWilliams. I will post a link to a PDF of newer edition of the full book at the end of the thread. If someone has a better "ALT" trick, please educate me on this one.

#2 – Projection – When someone takes what they are feeling and attempts to put it on someone else to artificially reduce their own anxiety.

Examples:

“Stop living in fear.” (the attacker is living in fear)

“You can take your mask off.” (they are insecure about being unmasked themselves)

“When are you going to stop masking?”

“You can’t live in fear forever.”This is from a psychology book by Nancy McWilliams. I will post a link to a PDF of newer edition of the full book at the end of the thread. If someone has a better "ALT" trick, please educate me on this one.
Image

Image
#3 – Displacement – When someone takes their pandemic anxiety and redirects their discomfort toward someone or something else.

Examples:

Angry, seemingly inexplicable outbursts by co-workers, strangers, or family

White affluent people caring less about the pandemic after learning that it disproportionately affects lower-socioeconomic status people of color

Scapegoating based on vaccination status, masking behavior, etc.

“Pandemic of the unvaccinated”

Vax and relax

“How many of them were vaccinated?” (troll comment on Covid deaths or long Covid)

Redirecting anxiety about mitigating a highly-contagious airborne virus by encouraging people to do simple ineffective mitigation like handwashing

“You do you” (complainers are the problem, not Covid)

Telling people to get vaccinated or take other precautions against the flu or RSV but not mentioning Covid

Parents artificially reducing their own anxiety by placing children in poorly mitigated environments

Clinicians artificially reducing their own anxiety by placing patients in poorly mitigated environments

Housework to distract from stress

Peer pressure not to maskThis is from a psychology book by Nancy McWilliams. I will post a link to a PDF of newer edition of the full book at the end of the thread. If someone has a better "ALT" trick, please educate me on this one.
Image
#4 – Compartmentalization – Holding two conflicting ideas or behaviors, such as caution and incaution, rather than dealing with the anxiety evoked by considering the incautious behaviors more deeply (hypocrisy)

Hospitals and clinicians claim to value health/safety but then don’t require universal precautions

Public health officials claim to value evidence but then give non-evidence based advice (handwashing over masking), obscure or use low-value data over high-quality data (self-reported case counts over wastewater), etc.

Getting a flu vaccine but not a Covid vaccine

Interviewing long Covid experts who recommend masking in indoor public spaces but then going to Applebee’s

Masking in one potentially risky setting (grocery store) but not masking in another similar or more-risky setting (classroom)

Infectious disease conference where people are unmasked

Long Covid and other patient-advocacy meetings where only half the people mask

In-person only EDI events

Not testing because it’s just family

Mask breaksThis is from a psychology book by Nancy McWilliams. I will post a link to a PDF of newer edition of the full book at the end of the thread. If someone has a better "ALT" trick, please educate me on this one.
#5 – Reaction formation – expressing artificial positive feelings when actually experiencing anxiety

“It’s good I got my infection out of the way before the holidays”

“I had Covid but it was mild”

Anything quoted in Dr. Jonathan Howard’s book, “We Want Them Infected: How the Failed Quest for Herd Immunity Led Doctors to Embrace Anti-Vaccine Movement”

Herd immunity (infections help)

Hybrid immunity (infections help)

“It’s okay because I was recently vaccinated”

“Omicron is milder”

“Textbook virus”

“Building immunity”This is from a psychology book by Nancy McWilliams. I will post a link to a PDF of newer edition of the full book at the end of the thread. If someone has a better "ALT" trick, please educate me on this one.
Image
Image
#6 – Rationalization – Artificially reducing Covid anxiety through a weak justification.

Examples:

“I didn’t mask but I used nasal spray”

“I don’t need to mask because I was recently vaccinated”

“It finally got me.”

“You’re going to get Covid again and again and again over your life.”

“It’s not Covid because I don’t have a sore throat.”

“It’s not Covid because I took a rapid test 3 days ago.”

“It’s not Covid because I’m vaccinated.”

“Airplanes have excellent ventilation.”

“I’ve had Covid three times. It’s mild.”

“Verily was cheaper.”

“Nobody else is masking.”

“Nobody else is testing.”

“My roommates don’t take any precautions, so there’s no point in me either.”

“I have a large family, so there’s no point in taking precautions.”

Surgical masks (they are actual “procedure masks,” by the way)

Various pseudo-scientific treatments used by the left and right

Handwashing as the primary Covid public health recommendation

Droplet transmission as a thing

Public health guidance that begins with “data shows” (sic)

Risk maps that never turn deep red

5 expired rapid tests

“Masks recommended” instead of universal precautions

“Seasonal”This is from a psychology book by Nancy McWilliams. I will post a link to a PDF of newer edition of the full book at the end of the thread. If someone has a better "ALT" trick, please educate me on this one.
Image
#7 – Intellectualization – using extensive cognitive arguments to artificially circumvent Covid anxiety

Examples:

Unending threads to justify indoor dining

Data-rich public health dashboards that use low-quality metrics and/or don’t change public health recommendations as risk increases

The entire justification for “off-ramps”

Oster, Wen, Prasad

Schools denying air cleaners because it “could make children anxious”

Schools not rapid testing this surge because it “could make children anxious”

The mental gymnastics underlying the rationales for who can get vaccinated, how frequently, or with what brand

Service workers told not to mask because it could make clients uncomfortable

“What comorbidities did they have?”

“The vulnerable will fall by the wayside”

Musicians and others holding large indoor events

5-day isolation periodsThis is from a psychology book by Nancy McWilliams. I will post a link to a PDF of newer edition of the full book at the end of the thread. If someone has a better "ALT" trick, please educate me on this one.

Here's a link to the full book, a newer edition than what I own. The information on defense mechanisms begins on textbook page 100.

Please let me know if there's a more accessible alt-text solution that you would prefer so I can do better next time.

PMC COVlD Wave Update (Europe)
11 October 2025 🧵

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...

1/ world map, nations with surveillance shown in blue. URL says pmc19.com/global
Data in #Austria show a rising COVlD wave. The x axis (bottom) has infrequent labels, but the data shown go through October 8th.

COVlD levels have been percolating in #Belgium, with "moderate" levels overall.

The transmission pattern is similar across regions. Plants at Namur-Brumagne and Oostende report "high" levels.

PMC COVlD Update, Week of Oct 6, 2025 (U.S.)
🧵1/9

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.Heat map, grayed out. 1 in 81 estimated actively infectious, or 602,000 new daily infections, per wastewater-derived estimates.

BREAKING: 3 State Pharmacy Boards Still Block COVlD Boosters without a Prescription

ACIP voted against prescriptions for boosters & 47 states + DC follow that guidance.

Georgia, Missouri, & Louisiana require prescriptions.

Key points in my letter to the pharmacy boards. 🧵1/7 Map shows only Missouri, Louisiana, and Georgia are blocking residents from routing COVlD boosters unless they have a prescription.
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 Georgia:  State law does NOT require a prescription if it is a “vaccine that is included on the adult immunization schedule recommended by the Advisory Committee on Immunization Practices (ACIP)”1 ACIP voted against prescriptions, and 47 states have accepted that schedule.  The law does not mention a CDC Director sign-off, which may be delayed months. Act now to save lives.  1. https://law.justia.com/codes/georgia/title-43/chapter-34/article-2/section-43-34-26-1/
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.

🧵3/7 Louisiana:  State law does NOT require a prescription if the “vaccine is administered in conformance with the most current immunization administration protocol as set forth by the United States Centers for Disease Control and Prevention Advisory Committee on Immunization Practice.” 2 ACIP voted against prescriptions, and 47 states have accepted that protocol.  The law does not mention a CDC Director sign-off, which may be delayed months. Act now to save lives.  2. https://law.justia.com/codes/louisiana/revised-statutes/title-37/rs-37-1218-1/

I remember when they said kids don't transmit COVlD much because they are short, small, and have tiny lungs. They lied.
I remember when they said COVlD doesn't transmit in schools. They lied.
I remember when they said COVlD is mild in kids without understanding post-acute sequelae. They lied.

PMC COVlD Update, Sep 29, 2025 (U.S.)

Summary: COVlD is everywhere.

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).

New York had *huge* retroactive upward corrections, and is now "High," as many residents hypothesized.

BREAKING: COVlD transmission surges across the Northeast amid 11th wave.

CDC levels & PMC prevalence estimates:
🔹CT: Very High (1 in 18 people actively infectious)
🔹RI: High (1 in 33)
🔹NY: High (1 in 35)
🔹MA: High (1 in 37)

Quick thread 🧵 1/7 Heat map from CDC data with PMC prevalence estimates noted in post
#NewYork has "High" transmission statewide & many counties are seeing "Very High" transmission, per CDC.

PMC estimates 1 in 35 people are actively infectious statewide.

A lot of sites are offline, but notice the overall coverage remains strong. Bad picture statewide.
🧵 2/7 Heat map with prevalence estimate, noted in post
In #Connecticut, we estimate 1 in 18 people are actively infectious. The CDC indicates "Very High" levels.

Statewide coverage is good. Assume it's very high risk everywhere.
