Newly Released Fauci Texts Reignite Debate Over COVID Mask Guidance
Newly released private communications involving former National Institute of Allergy and Infectious Diseases Director Anthony Fauci are once again fueling the truth over how federal health officials handled COVID-19 policy and public messaging.
Several weeks ago, Sen. Rand Paul released private texts and messages involving Fauci, bringing the former public health official back into the national spotlight. Critics have seized on the material, dubbed the “Fauci diaries,” arguing that the private communications paint a very different picture from the public image Fauci maintained during the pandemic.
The text messages released by Sen. Ron Johnson showed Fauci privately discussing concerns about possible COVID vaccine side effects involving pregnant women.
Now, another set of messages is drawing attention, this time focusing on masks, aerosol transmission and the scientific evidence officials were relying on when making recommendations to the public.
Osterholm’s Private Message
Michael Osterholm an epidemiologist and professor at the University of Minnesota who also serves as director of the Center for Infectious Disease Research and Policy (CIDRAP).
CIDRAP drew considerable attention during the early months of the pandemic after publishing an April 2020 article questioning the evidence supporting cloth masks as a means of limiting COVID-19 transmission. The organization subsequently issued clarifications as the debate surrounding masking intensified.
In August 2021, Osterholm sent a text message addressed to “Jeff, Vivek, Tony and Rochelle.” Those recipients as likely being then-White House COVID response coordinator Jeff Zients, Surgeon General Vivek Murthy, Fauci and then-CDC Director Rochelle Walensky.
Osterholm began the message with a striking statement:
“Dear Jeff, Vivek, Tony and Rochelle, I’m sending this via text messaging to avoid any FOIA issues,”
What did they have to hide?
He then addressed comments he had made about cloth face coverings:
“On Friday a Newsmax reporter asked Jen Psaki about my comments on face cloth coverings and protection against SARS-CoV-2 transmission. The reporter completely mischaracterized my comments made on numerous occasions over the past 16 months about ‘masks’ and the prevention of SARS-CoV-2 transmission. She was taking the Florida governor’s approach. Since April, 2020, I have been consistent in my messaging about the roles that aerosols play in transmission, and the limited benefit that cloth face coverings play in reducing risk.”
The message is significant because Osterholm was privately emphasizing the “limited benefit” of cloth face coverings at a time when masking remained a major component of the government’s COVID response.
There was a stark disconnect between what some public health experts understood about aerosol transmission and the broad promotion and enforcement of cloth masking across the United States.
Evidence Shows Cloth Masks Did Nothing!
Osterholm’s message went further, pointing the recipients toward information from an industrial hygiene organization examining respiratory protection.
He wrote:
“N-95s are necessary to be effective reducing risk with aerosol transmission. Here is a link to the ACGIH website (the national industrial hygienists expert group on respiratory protection.) Note the very limited protection from face cloth coverings versus no respiratory protection at all.”
Osterholm nevertheless continued to support masking, specifically advocating higher-quality N95 respirators rather than ordinary cloth face coverings.
But perhaps the most consequential part of his message concerned the scientific research being cited by the CDC to support cloth masking.
Osterholm wrote:
“CMS has supported an expert review group process for evaluating respiratory protection studies since the early days of the pandemic and have found none of the studies that CDC uses to support its statement as to the significant protection of face cloth coverings stand up to scientific scrutiny,”
That statement raises questions about what senior public health officials privately understood regarding the quality of the evidence supporting cloth masks and how that compared with the message being presented publicly.
For critics of pandemic-era mandates, the significance is difficult to overlook. Fauci, Walensky and other senior officials were highly credentialed scientists capable of evaluating the strengths and weaknesses of medical research. The newly released communication therefore adds fuel to longstanding criticism over whether mask policies were promoted with greater certainty than the underlying evidence justified.
Osterholm Criticized the CDC’s Response to Aerosol Transmission
Osterholm also criticized the CDC for taking too long to recognize the importance of aerosol transmission.
He wrote:
“As we all know, CDC was very late to the game recognizing that aerosols play a significant role in the transmission picture. Just look at the current US map of Delta activity and see how fast and far it has spread throughout the US. This is largely aerosol transmission driven, not respiratory droplets,”
The distinction between aerosols and respiratory droplets was a major issue during the pandemic because it directly influenced recommendations surrounding masks and other mitigation measures. Osterholm’s message indicates that, by August 2021, he believed aerosol transmission was playing a major role in the rapid spread of the Delta variant.
He continued to advocate the use of N95 masks, but concluded his message with a prediction about how the government’s handling of masking would eventually be remembered:
“I am certain one day that one of the take-away findings of this pandemic was the constant USG emphasis on masking while at the same time providing minimal guidance to the public what effective masking means.”
The newly released texts provide another window into the discussions taking place among influential public health figures while COVID policies were being developed and defended publicly. They also revive questions about the gap between the uncertainty expressed privately among experts and the far more definitive messaging Americans frequently received from government institutions.
Even N95 mandates ultimately failed to produce the promised results. It points to German states that required N95-grade masks and says those states subsequently reported higher case rates than states with less stringent mask requirements.
Whatever conclusions are drawn from the messages, Osterholm’s private comments have once again placed pandemic-era masking policies — and the scientific evidence officials used to justify them — under renewed scrutiny.
