Dear President Biden,
On Sunday 3/21/21 you tweeted the following words of high praise for the CDC: "The CDC represents the best of this nation. Brilliant minds. Deep faith in science. And a strong commitment to public service. On Friday, Vice President Harris and I stopped by to thank them for all the work they do."
Your gracious compliments may be valid for most of the CDC's staff, but certainly not for the CDC as a whole. Most close observers of the CDC's performance in 2020 and thus far in 2021 have expressed profound disappointment.

Rather than present a lengthy review of every one of the CDC's important blunders, this discussion focuses on masks because 20-20 hindsight makes it clear that the CDC's mismanagement of masks was a catastrophic fumble that cost hundreds of thousands of lives. This harsh assessment will be explored via three scenarios: ideal, real, and prospective.
- Everyone who wore N95 respirators would be able to engage in face-to-face encounters with other people regardless of whether the others were wearing masks, just like doctors, nurses, and other health care providers.
- People who refused to wear N95 respirators would be risking their own health, but they would not pose health threats to people who wore masks, especially if the mask wearers maintained a social distance from the non-mask wearers as an extra precaution.
- The vast majority of mask wearers would have been able to continue working in their usual offices and other work place environments and the need for lockdowns and other severe disruptions of employment would have been minimized ... perhaps with some social distancing in order to accommodate the presence of non-mask wearers who were critical to an organization's operations
In particular, schools at all levels would have been able to maintain their traditional face-to-face classroom arrangements for students, faculty, and staff who wore masks.
Exception: restaurants would have had to impose social distancing because their customers would have to remove their masks while they were eating. - Mask wearers would have been able to maintain their usual face-to-face social relationships.
In particular, mask wearers would have been be able to visit sick and dying relatives in hospitals and nursing homes. - Mask wearers would have minimum concern about significant virus mutations that reduced the effectiveness of the latest vaccines that were available as long as the mutation did not develop significant non-respiratory transmission capabilities.
Bottom line: Had the U.S. been able to follow this ideal scenario, the mitigation policies needed to manage the pandemic would have been far less stressful for most of the U.S. population; hospitalization and death counts would have been a fraction of the hospitalizations and deaths that actually occurred; and the recovery funds needed to get the economy back on track would have been measured in billions of dollars, an order of magnitude smaller rather the multi-trillion dollar costs that were actually incurred. After vaccines were developed, if substantial variants of the virus appeared, vaccinated members of society would merely resume their use of N95 masks until they received updated versions of the vaccine that provided protection against the new variants.
- Shortage and confusion
In early March 2020, the anticipated demand for N95 respirator masks by doctors, nurses, and other COVID-19 health care professionals greatly exceeded the supply from existing N95 providers. The CDC and its health care associates on President Trump's Task Force were so concerned that non-medical customers would buy the scarce N95 respirators that they initially discouraged the public from buying any kind of masks at all.
In their television presentations the CDC Director and the other members of the Task force asserted again and again that the only masks that provided effective protection against COVID-19 were the scarce N95 respirators. Moreover, wearing ineffective masks might provide wearers with a false sense of protection that might make them less likely to maintain social distancing, wash theirs hand frequently, and other effective coronavirus prevention practices.
However, a few weeks later the CDC and its Task Force associates suddenly reversed their position. Now they proclaimed that non-N95 masks were good things that would significantly reduce the spread of the virus. The public was confused by this reversal, but most people began to wear masks anyway. While non-N95 masks did not offer substantial protection for their wearers, the CDC argued that their widespread use within communities would substantially reduce the spread of the virus within those communities.
Subsequent studies confirmed that communities wherein most people wore masks experienced rates of infection that were much lower than communities wherein masks were not prevalent. Please take a look at two comprehensive reviews: "Face masks: what the data say", Lynne Peeples, Nature, 10/6/20 ... and the more recent "An evidence review of face masks against COVID-19", Jeremy Howard et al., PNAS, 1/28/21
It is important to note that these two comprehensive reviews could not cite any studies about masks and the coronavirus that were published before June 2020 when the first paper providing direct evidence about masks impeding the coronavirus appeared. Indeed, the October 2020 review in Nature admitted as much:
"At the beginning of the pandemic, medical experts lacked good evidence on how SARS-CoV-2 spreads, and they didn’t know enough to make strong public-health recommendations about masks." [bold added by editor]
The CDC's initial recommendation in early March 2020 that strongly opposed the wearing of non-N95 masks was a bad judgement call; however the CDC's flip-flop a few weeks later to recommending non-N95 masks was a good judgement call because it subsequently received substantial support from the many other scientific studies cited by the Nature and PNAS reviews.
The point here is that the CDC should not confine its recommendations to those that are based on science. It must also make judgement calls informed by science, but ultimately based on experience. - Double masking
Careful observers of our efforts to manage the pandemic were noting as early as June 2020 that the CDC's haphazard approach to masks was not sufficient. For instance, see the following article:"We Need Better Masks", Ranu S. Dhillon, Abraar Karan, David Beier, and Devabhaktuni Srikrishna, Harvard Business Review, 6/18/20.
This article's second paragraph reads as follows: "Testing remains an order of magnitude short of what is needed, and a vaccine won’t be available until at least early next year [2021]. But we could potentially achieve control and confidence now if better masks were available for the general public that are more protective than the cloth ones worn now and closer in caliber to the N95 and high-filtration surgical masks used by health workers."
The most obvious improvement that would have required no time or effort to develop and market would have been two masks, e.g., wearing a cloth mask over a surgical mask. If the CDC suspected that a single mask might reduce the number of infections, hospitalizations, and deaths, why didn't it consider potential further reductions from double masking? Alas, the CDC did not see fit to recommend double masking until February 2021. (See "Masks should fit better, or be doubled up to protect against coronavirus variants, CDC says", Lena H. Sun and Fenit Nirappil, Washington Post, 2/10/21.) - N95 respirators, but only for health care personnel
The scarcity of N95 respirator masks at the start of the pandemic in early 2020 -- i.e., lack of stockpiles and lack of U.S. providers ready to ramp up production -- reflected years of underfunding of the CDC and its state-level public health affiliates. However their continued scarcity throughout the pandemic reflected bad judgments by President Trump and by the leadership of the CDC and their associates on Trump's Task Force.
President Trump had been briefed in January 2020 that the coronavirus posed a clear and present danger to the U.S., a threat that he took very seriously. His response to this threat was Operation Warp Speed, a multi-billion dollar high speed initiative to develop effective vaccines by the end of 2020, vaccines that would enable the U.S. population to achieve herd immunity.

-- Trump’s ‘Operation Warp Speed’ Aims to Rush Coronavirus Vaccine", Jennifer Jacobs and Drew Armstrong, Bloomberg, 4/29/20
Meanwhile, he needed to carry out two holding actions: (a) provide sufficient N95 respirators and other personal protective equipment to health care personnel, and (b) use social mitigation to keep the levels of infections and hospitalizations from overwhelming the U.S. healthcare system. Unfortunately, both holding actions failed.
President Trump invoked the the Defense Production Act of 1950 to expand the domestic production of N95 respirators for health care providers just once, a timid action that commanded one company, 3M, to increase its output; but the contracts did not go into effect until May 2021 ... but they were too little, too late. This left the health care providers, governors, mayors, and others to continue competing against one another for still scarce respirators from the usual suppliers in a wasteful bidding war.

-- "3M Awarded Department of Defense Contracts to Further Expand U.S. Production of N95 Respirators", 3M, 5/7/20
Social mitigation also failed to block the expansion of the virus. The CDC and its Task Force associates must have convinced President Trump that a nation-wide lockdown, the ultimate mitigation, lasting no more than three or four weeks starting in March2020 would reduce the future spread of the virus to manageable levels; but it didn't.
Correction: the partial lockdown that actually resulted from voluntary compliance with the Task Force recommendations was sufficient to wreck the U.S. economy, but not sufficient to block the continued spread of the virus. It is difficult to understand how the CDC could have anticipated success at a time when there were fewer than 20,000 known cases of COVID in less than 10 states, nor would the virus reach many other states until weeks or months thereafter. (Note: 20,000 cases in a U.S. population of 330,000,000 represents an infection of rate 0.006 percent)
"A Striking Disconnect on the Virus: Economic Pain With Little Illness", Michael H. Keller, Steve Eder and Karl Russell, NY Times, 6/6/20
Seeing no cases, substantial segments of the people in the other 40 states thought the pandemic was greatly exaggerated or a hoax; so they didn't maintain social distancing nor wear masks. Beyond this, the CDC was requesting a high degree of cohesive action at a time in which the country was more divided than at any time since the decades immediately preceding the Civil War. Indeed, less than half of the population expressed approval of the president, which undermined their trust in his appointed leaders of the CDC and their associates on his Task Force.
President Trump's angry disappointment at the end of April six weeks later led to his confusing efforts to pull all states come out of lockdown, regardless of the status of the virus in each state.

A pandemic "Big Lie"
Despite repeated references to "the science" by the CDC, the Task Force, and liberal/progressive pundits as the basis for the CDC's recommendations for managing the pandemic: there is no such thing as a science of pandemic management.
To be sure, there are relevant biological sciences -- e.g., epidemiology, virology, and genomics -- that might be referenced together as "the science". But there is no body of reliable, data-driven scientific theories about how to change the lifelong habits of a super majority of our citizens so as to win a total war against a virus whose infections have massive impact on the families, educational institutions, local economies, personal relationships, and the individual psychologies of large segments of our population. Why? Because we have only had one other pandemic in the last hundred years, so there has not been sufficient opportunity for researchers to conduct the extensive, multidisciplinary studies required to develop a reliable science of pandemic management.

The CDC's surprise announcement was all the more head spinning because just a few weeks earlier, the director of the CDC had declared that she was scared that our country was facing "impending doom"
- "CDC director warns of 'impending doom' as Covid-19 cases spike in most states", Christina Maxouris and Holly Yan, CNN, 3/29/21
The CDC fumbled the mask issue from the first days of the pandemic, so it is not surprising that the CDC should end the pandemic with another fumble. Throughout the pandemic the CDC's public presentations emphasized national statistics about infections, hospitalizations, deaths, and more recently, vaccinations as appropriate measures for determining social mitigation policies. The CDC never grasped the unavoidable political interactions between the fundamental characteristics of the virus and our federal system:
- COVID-19 is a local disease that spreads across very short distances primarily by riding the slow moving exhalations of infected persons, then hopping onto the slow moving inhalations of uninfected persons. Hence the COVID statistics that matter most are not national statistics, but the local statistics about vaccinations, infections, hospitalizations, and deaths at state, county, and urban levels. Decisions as to when people should stop wearing masks should be made by local authorities after considering their local statistics.
Governors have this authority. The CDC, after reviewing national statistics, might have strongly recommended that the nation's governors consider dropping mask requirements if their local statistics met a set of criteria suggested by the CDC. Then governors should have be praised or damned according to how well or poorly their decisions fit the specific conditions of their local communities.
Trump's tactical irresponsibility
C. Prospective scenarios
Yes, an extensive bipartisan Congressional investigation is mandatory .... but ... in the current divisive political environment, such an investigation would probably take months to organize, followed by more months of investigation, followed by more months of debate about the findings ... months and months and months during which the current CDC would continue to fumble.

- Given that the percentage of unvaccinated persons varies from state to state, some states will enjoy a return to normal before others; but Black, Hispanic, and other minorities are disproportionately unvaccinated in most states. Accordingly, some states may continue to experience substantial surges in infections, hospitalizations, and deaths, but at substantially lower rates than in 2020. Nevertheless, the death rates from COVID may be twice as high as the death rates in bad flu seasons. (See "A rough estimate of future COVID deaths now that herd immunity is unlikely", on this blog, last update: 5/10/21)
- The emergence of resistant variants will require updates to current vaccines from time to time, a need that will also vary from state to state; but we should again anticipate that minorities will be disproportionately non-updated in most states.
