When it became clear that the United States would require a coordinated, national effort to “contain” the coronavirus outbreak, many people assumed the Trump Administration would choose former FDA Commissioner Scott Gottlieb to lead it.

He would have been a superb choice. Dr. Gottlieb is smart, knowledgeable, highly respected, politically adept. Passed over for the role of head coach, he’s been the news media’s “go-to” former government official for coronavirus assessment, analysis and commentary. A number of leading investment firms and business organizations have also called upon him for the his expertise and level-headed guidance.

Yesterday, Dr. Gottlieb posted a lengthy “thread” on Twitter, which I have copied and pasted below. It’s worth reading in full.

Thread:

#1) On #Coronavirus, we may be entering a period of accelerating cases. The country could look very different over next two weeks. We’ll get through this, but need to take steps now to limit the scope and impact of virus. There are things we can do now to help ourselves.

#2) In last 10 days Italy diagnosed 95% of total cases they now report; South Korea 85%. 2 weeks ago, Italy had just 9 cases. 7 weeks ago, China reported 50 cases. The point: once the epidemics are discovered, they’ve been underway. Case counts grow quickly. Same likely true here.

#3) What should we do now? Moving quickly and aggressively to mitigate spread, reduce the scope of the epidemic here, continue to ready the healthcare system, work with cities and states to develop a uniform, systematic response; provide financial assistance to help these efforts.

#4) Mitigation: The goal is to reduce the number of cases at the peak of the epidemic. This extends the length of the epidemic, but can push the total number of cases at any one time below the point where the healthcare system gets exhausted, improving outcomes for patients.

#5) We need a uniform and timely approach to mitigation and social distancing that local, state officials can follow and clear set of principles on when to adopt the measures. School closures, event cancellations, other aggressive steps need to be implemented now in certain areas.

#6) We must support affected cities, states with financial assistance. The feds must strongly encourage states and cities that have outbreaks to take mitigation steps to help protect nation. But localities that take on these burdens should be compensated for hardships they incur.

#7) Simple measures still matter. Hand washing, avoiding crowded indoor spaces, cleaning surfaces, keeping people more apart where appropriate. Businesses and individuals are responding with prudent and measured action, and need to step up these efforts.

#8) There will be hardship especially among the vulnerable. We need to consider financial assistance; first aid through existing programs then perhaps a bigger supplemental. Many people can’t easily absorb missed work, closed schools. We must assist them for the measures to work.

#9) Businesses need to do their part by offering flexibility to workers in order to make these mitigation measures effective — telework, flexibility when schools are closed and parents must tend to children, avoidance of unnecessary travel especially to and from areas of spread.

#10) We will get through this. Some of these measures at social distancing, improved hygiene techniques, could persist. The epidemic will abate but outbreaks could occur again until we have a vaccine. Ultimately technology will vanquish this disease.

#11) This is a dangerous virus. We have faced worse, and prevailed. People will suffer and die. The most vulnerable are at greatest risk. We must all work together to protect them. The next few months will be hard, but we will preserve life, and eventually conquer this pathogen.

What impact will the coronavirus have on the healthcare system in the United States? A woman named Liz Specht addressed this question in a lengthy Twitter thread.

(Quick bio: Ms. Specht has a bachelor’s degree in chemical and bio-molecular engineering from Johns Hopkins University, a doctorate in biological sciences from the University of California San Diego, and postdoctoral research experience from the University of Colorado Boulder. Liz is a Community Fellow with CU Boulder’s Sustainability Innovation Lab and a Guest Lecturer for Singularity University. She has a decade of academic research experience in synthetic biology, recombinant protein expression, and development of genetic tools. Put simply: she’s really smart and she knows what she’s talking about.)

Her “thread” that follows is worth reading in full:

I think most people aren’t aware of the risk of systemic healthcare failure due to #COVID19 because they simply haven’t run the numbers yet. Let’s talk math. 1/n

Let’s conservatively assume that there are 2,000 current cases in the US today, March 6th. This is about 8x the number of confirmed (lab-diagnosed) cases. We know there is substantial under-Dx due to lack of test kits; I’ll address implications later of under-/over-estimate. 2/n

We can expect that we’ll continue to see a doubling of cases every 6 days (this is a typical doubling time across several epidemiological studies). Here I mean *actual* cases. Confirmed cases may appear to rise faster in the short term due to new test kit rollouts. 3/n

We’re looking at about 1M US cases by the end of April, 2M by ~May 5, 4M by ~May 11, and so on. Exponentials are hard to grasp, but this is how they go. 4/n

As the healthcare system begins to saturate under this case load, it will become increasingly hard to detect, track, and contain new transmission chains. In absence of extreme interventions, this likely won’t slow significantly until hitting >>1% of susceptible population. 5/n

What does a case load of this size mean for healthcare system? We’ll examine just two factors — hospital beds and masks — among many, many other things that will be impacted. 6/n

The US has about 2.8 hospital beds per 1000 people. With a population of 330M, this is ~1M beds. At any given time, 65% of those beds are already occupied. That leaves about 330k beds available nationwide (perhaps a bit fewer this time of year with regular flu season, etc). 7/n

Let’s trust Italy’s numbers and assume that about 10% of cases are serious enough to require hospitalization. (Keep in mind that for many patients, hospitalization lasts for *weeks* — in other words, turnover will be *very* slow as beds fill with COVID19 patients). 8/n

By this estimate, by about May 8th, all open hospital beds in the US will be filled. (This says nothing, of course, about whether these beds are suitable for isolation of patients with a highly infectious virus.) 9/n

If we’re wrong by a factor of two regarding the fraction of severe cases, that only changes the timeline of bed saturation by 6 days in either direction. If 20% of cases require hospitalization, we run out of beds by ~May 2nd. 10/n

If only 5% of cases require it, we can make it until ~May 14th. 2.5% gets us to May 20th. This, of course, assumes that there is no uptick in demand for beds from *other* (non-COVID19) causes, which seems like a dubious assumption. 11/n

As healthcare system becomes increasingly burdened, Rx shortages, etc, people w/ chronic conditions that are normally well-managed may find themselves slipping into severe states of medical distress requiring intensive care & hospitalization. But let’s ignore that for now. 12/n

Alright, so that’s beds. Now masks. Feds say we have a national stockpile of 12M N95 masks and 30M surgical masks (which are not ideal, but better than nothing). 13/n

There are about 18M healthcare workers in the US. Let’s assume only 6M HCW are working on any given day. (This is likely an underestimate as most people work most days of the week, but again, I’m playing conservative at every turn.) 14/n

As COVID19 cases saturate virtually every state and county, which seems likely to happen any day now, it will soon be irresponsible for all HCWs to not wear a mask. These HCWs would burn through N95 stockpile in 2 days if each HCW only got ONE mask per day. 15/n

One per day would be neither sanitary nor pragmatic, though this is indeed what we saw in Wuhan, with HCWs collapsing on their shift from dehydration because they were trying to avoid changing their PPE suits as they cannot be reused. 16/n

How quickly could we ramp up production of new masks? Not very fast at all. The vast majority are manufactured overseas, almost all in China. Even when manufactured here in US, the raw materials are predominantly from overseas… again, predominantly from China. 17/n

Keep in mind that all countries globally will be going through the exact same crises and shortages simultaneously. We can’t force trade in our favor. 18/n

Now consider how these 2 factors — bed and mask shortages — compound each other’s severity. Full hospitals + few masks + HCWs running around between beds without proper PPE = very bad mix. 19/n

HCWs are already getting infected even w/ access to full PPE. In the face of PPE limitations this severe, it’s only a matter of time. HCWs will start dropping from the workforce for weeks at a time, leading to a shortage of HCWs that then further compounds both issues above. 20/n

We could go on and on about thousands of factors — # of ventilators, or even simple things like saline drip bags. You see where this is going. 21/n

Importantly, I cannot stress this enough: even if I’m wrong — even VERY wrong — about core assumptions like % of severe cases or current case #, it only changes the timeline by days or weeks. This is how exponential growth in an immunologically naïve population works. 22/n

Undeserved panic does no one any good. But neither does ill-informed complacency. It’s wrong to assuage the public by saying “only 2% will die.” People aren’t adequately grasping the national and global systemic burden wrought by this swift-moving of a disease. 23/n

I’m an engineer. This is what my mind does all day: I run back-of-the-envelope calculations to try to estimate order-of-magnitude impacts. I’ve been on high alarm about this disease since ~Jan 19 after reading clinical indicators in the first papers emerging from Wuhan. 24/n

Nothing in the last 6 weeks has dampened my alarm in the slightest. To the contrary, we’re seeing abject refusal of many countries to adequately respond or prepare. Of course some of these estimates will be wrong, even substantially wrong. 25/n

But I have no reason to think they’ll be orders-of-magnitude wrong. Even if your personal risk of death is very, very low, don’t mock decisions like canceling events or closing workplaces as undue “panic”. 26/n

These measures are the bare minimum we should be doing to try to shift the peak — to slow the rise in cases so that healthcare systems are less overwhelmed. Each day that we can delay an extra case is a big win for the HC system. 27/n

And yes, you really should prepare to buckle down for a bit. All services and supply chains will be impacted. Why risk the stress of being ill-prepared? 28/n

Worst case, I’m massively wrong and you now have a huge bag of rice and black beans to burn through over the next few months and enough Robitussin to trip out. 29/n

One more thought: you’ve probably seen multiple respected epidemiologists have estimated that 20–70% of world will be infected within the next year. If you use 6-day doubling rate I mentioned above, we land at ~2–6 billion infected by sometime in July of this year. 30/n

Obviously I think the doubling time will start to slow once a sizeable fraction of the population has been infected, simply because of herd immunity and a smaller susceptible population. 31/n

But take the scenarios above (full beds, no PPE, etc, at just 1% of the US population infected) and stretch them out over just a couple extra months. 32/n

That timeline roughly fits with consensus end-game numbers from these highly esteemed epidemiologists. Again, we’re talking about discrepancies of mere days or weeks one direction or another, but not disagreements in the overall magnitude of the challenge. 33/n

This is not some hypothetical, fear-mongering, worst-case scenario. This is reality, as far as anyone can tell with the current available data. 34/n
