Ebola, Risk Management, and the Case for Principled Pragmatism
Earlier this morning, the State of New Jersey agreed to release nurse Kaci Hickox from forced custody and allowed her to return to her home to serve out the remainder of her government-madated ebola quarantine.
Hickox’s demand to be released was just the latest sub-chapter in what has been a barrage of news media coverage over the the deadly disease. To date, half-a-half-dozen new domestic ebola cases have been reported and, at least as of now, there is no indication that the disease has not been successfully contained within US borders. Despite this, ebola coverage is largely dwarfing and crowding out every other national news story, including stories about an impending election which could well shift political power in the US Senate. Mind you, that people might assign greater urgency to ebola than the midterm polls, the World Series, and the cancellation of Honey Boo Boo is probably as it should be. A modern day plague is, after all, about as terrifying a thought as I could imagine.
What I find curious and disconcerting about the ebola coverage is not it’s media ubiquitousness, therefore, but rather how the media has allowed the various risk management strategies considered to be turned into a Republican vs. Democrat/Conservative v.s Liberal issues. They’re not, and treating them as such can actually have disastrous consequences.
To show you what I’m talking about, it’s probably best to start with the risk management piece of the equation.
In risk management terms, an ebola outbreak is one that has limited frequency risk and great severity risk — that is to say, statistically speaking it almost never happens (worrying about an imminent US ebola outbreak has actually been a thing since 1994), but when it does occur the results can be catastrophic. It’s self-evidently awesome that ebola outbreaks are so infrequent. But one of the downsides to risks that are realized infrequently is that we have less data from which to extrapolate the best response when the event does occur. Hurricanes happen multiple times every year, and as a result we know with exact precision what to do when one occurs.[1] But an ebola outbreak on US soil? Not so much. When determining the best strategy to curb a possible domestic ebola outbreak, there are tens of thousands of variables that have to be taken into consideration. And while some have to do with obvious cultural and legal issues, many more have to do with things that we can neither control nor fully anticipate.
For example, a no-fly zone from West African might reduce the risk of people infected with ebola entering the United States — or it might not. If you assume that people will still continue to enter and exit West Africa, then a no-fly zone might well result in people finding other channels which are monitored either less diligently or scrupulously. And since an infected person forced to exit West Africa by boat or train can pass along the disease to a US citizen in, say, Istanbul just as easily as they can pass it along in Dallas, a no-fly zone is not actually an elimination of risk so much as it is a transfer to a different kind of risk. A no-fly order, therefore, could drastically reduce the number of infecteds that enter the US — but it could also increase the number of infected that enter the US in ways where no monitoring is occurring.
Which is the best single method to ensure the least likely possibility of outbreak — no-fly/low control or allow-flight/high control? The answer is that no now really knows, and that even if we did we’d be talking in terms of various probabilities and not absolutes. And if that sounds overly scary, know I don’t meant it to be. “No one really knows” is the starting point of most good risk management strategies.
In fact, the best strategy for a scenario as complex as an ebola outbreak is most likely one that incorporates all of the available options at various junctures. Indeed, long before the first ebola diagnosis was confirmed in Texas there was probably a response matrix already in place that did just this. And that matrix no doubt goes in different directions, each one depending upon a set of exact and unique circumstances. In terms of flight restrictions, its matrix almost certainly has Status Quo when we are at Point X, Targeted Flight Restrictions when we reach Point Y, and No Non-Domestic Flights of Any Kind once we get to Scary-Ass Point Z. Having such a matrix does not guarantee that an ebola outbreak will not happen; one might. Rather, the matrix simply details the points at which certain risk-trade-offs will be made in various scenarios. And at least at the moment, the CDC’s ebola strategy matrix appears to be doing an admirable job. Two infected people entered the US unaware that they were incubators, and the result thus far is one death, one confirmed case of a US infection, and apparent overall containment.[2]
But now, however, there is pressure to abandon the CDC’s risk matrix because ebola has apparently become a Red State/Blue State issue.
Shortly after the first case was recorded in Dallas, the media began to allow conservative politicians to stake out territory that being anti-ebola was somehow conservative. For the past several weeks, we have seen ebola attached to a number of preexisting political conditions, ranging from border patrols to ISIS to immigration policy — none of which have much of anything to do with ebola, and none of which have anything remotely to do with the CDC risk management policy being deployed. The end result of this odd politicization has been that the no-fly option has bizarrely become a Right/Left litmus test.
On one side, you have conservative candidates and journalists taking up the arms for an immediate no-fly response, without — so far as I can see — any consideration at all given to how such an approach would sacrifice the over-all situation control that such a change would carry. On the other side, you’re beginning to see an almost lockstep pronouncement that a no-fly would somehow be anti-science, despite the fact that at some point under certain scenarios it will certainly be prudent to impose one. The problem, of course, is that either position — No-Fly Is The Answer! or No-Flys Are Un-Scientific! — is a potentially disastrous position to take.[3]
When I talk about why I am a principled pragmatist first — and why I think in our increasingly bubbled world ideology is the enemy — this is what I’m taking about.
In my very post post ever here, I said this about what happens when political “values” meet OSHA worker safety regulations:
You might think that the solution is relatively easy, then. In the real world, however, it isn’t – because ideology gets in the way. Battle lines are drawn between Rs and Ds, even though none are truly required. (Management and labor are almost always in agreement on these issues; pols not so much.) … But as so often happens, ideology trumps reality, and data is dismissed as irrelevant or conspiracy. The best the building industry on the whole can hope for is that both sides arrive at some kind of angry compromise that isn’t a total fish up. The worst that can happen is that one side outright wins.
I might have written that about the way we are talking about the ebola crisis. The difference is that now the stakes are potentially far, far greater.
The risks of an ebola epidemic is not the same abortion; the strengths and weaknesses of the strategies involved are not akin to what those who make $200,000 a year should be taxed. Risk management is neither a conservative nor progressive value. Your political avatars might be telling you that they in fact are, but your political avatars are lying to you in order to get you to feed your ideology.
Listening to these voices to the point where you increase the risk of a bad credit rating is stupid; doing it to the point where you increase the risk of a disastrous epidemic is criminal.
[2] A possible third infected citizen, a five-year old boy, might be added to those statistics by the end of today.
[3] Not that there aren’t some admirable exceptions. Or one, anyway.
Seriously, if you would have told me twenty years ago that everyone in politics was putting the nation at risk to leverage some votes in a midterm election, and that the one Senator who refused to do so was the guy who played Stuart Smalley, I would have thought you a loon.

I didn’t click through the links, but 538 did an analysis of the impact of a flight ban. They found relatively few direct flights from the infected areas to the US. But many, many, many flights that involved connections in Europe or the Middle East. The latter group could not be controlled for. We can’t tell Nigerian Air they can’t fly to Istanbul and we can’t block all flights from Istanbul. For me, this was more or less the definitive argument, at least given the facts as we currently know them.
One of my favorite games to play is to identify a hot button political issue (“EBOLA!”) and construct an argument for each side of the aisle both for and against it. The reality is, you can do this almost all the time. For instance, if a Republican was in the White House, I could easily see conservatives insisting that Ebola was a bunch of unsubstantiated media hype while liberals would probably insist the President was ignoring the crisis because it was African in origin.
Good post, Tod.Report
Well, I’ve been on the fence for quite a while. But I think I’m going to come down against ebola.Report
Why do you hate Africa?Report
In this case it seems that ideology is the secondary enemy, politics is the first. Politics wouldn’t even be that big a deal if pols and media types weren’t rewarded with fear mongering and there was more focus on letting people who know something about the sporking subject lead us (yes the dreaded techocrats).Report
Like you’d say Ebola was more important than the Series if the Bums had made it in.Report
The one I don’t get (or wish I didn’t get) is this: it has now become a right-left isue whether people who are known for a fact to have been exposed to Ebola should be quarantined until it’s certain they weren’t infected. This after a doctor who had been exposed walked around freely not knowing he was both sick and contagious. How is quarantine not a sensible, low-cost, high potential reward precaution?Report
Being a bit of a devil’s advocate, does that mean we can threaten the anti-vax crowd with quarantine?Report
If an anti-vaxxer has been exposed to a deadly communicable disease, than quarantine within the period he might be infected without showing symptoms seems reasonable to me.
If you mean “lock up everyone who hasn’t been vaccinated for measles forever” the risk-reward calculation changes quite a bit.Report
I’m not saying we do it. I just want to be able to threaten to do it.
I understand the practical desire for forced quarantine. And we obviously have a history of forcibly separating people from society if they pose a threat. But that is usually because of choices they’ve made that violate the law.Report
Define exposed? Should everyone that was on the same subway as that doctor be quarantined? The issue is one of incentives. If all aid workers are guaranteed a 21 day quarantine, no matter their condition, then we’ll get a lot fewer aid workers and it’s much more likely that the Ebola problem will get worse, rather than better.Report
Really, going to Africa for months of living in primitive condititons with the constant risk of contracting Ebola isn’t a disincentive, but a few weeks of isolation in relative comfort in the US is?Report
Mike,
what is your risk assessment here? We’re not talking having to jury rig protective gear out of anything you can, like we were when Marburg struck Uganda. And Marburg had a higher deaths per infection rate.Report
@mike-schilling You mean helping people out and doing good with your skills is somehow less appealing than being locked up because someone wants to ignore epidemiology to pander to constituents? If a 4 week stint with MSF is actually a 4 week stint with MSF and a 3 week stint locked in a hospital (or worse a 1 week stint with MSF and 3 weeks in a hospital because you only want to take a month off), the incentives change significantly. Especially if you’re a nurse and you can’t afford to take that much extra time off work.Report
Ignore epidemiology, as in insist that someone treating Ebola victims may himself become infected, just because it actually happened?
And, by all means, compensate people for the time they’re quarantined. Find them useful work to do: research, planning, relating their experiences. Give them pleasant surroundings. But don’t jerk your knee against isolating them just because it’s something Sean Hannity likes.Report
I’m not against isolating high risk cases or if the disease was more contagious. There are significantly more people that did work in Ebola areas that did not get Ebola. And despite bringing it back, the doctor didn’t infect anyone else because he checked himself in before he was contagious. What;s the percentage of health care workers that brought back the disease? 1%? 2%? There’s a line where a universal quarantine is valid, but we haven’t hit that point yet.Report
Mike,
Are you listening to me at all???? Quarantine is ONLY NEEDED when they’re contagious. This isn’t Tuberculosis, this is FAR MORE like AIDS. You KNOW IT when you’re contagious.
Quarantine is completely missing the point, anyhow. This is far more of a “sanitation” issue than a “oh my fucking god influenza” issue — the logistics on “how you deal with contaminated bedding’ are FAR MORE IMPORTANT than isolating people who might be a problem.
See HIGHLY INFECTIOUS DISEASE. It takes ONE virus, as far as we know, and you could be infected. EVERY SINGLE PERSON you quarantine now is generating LARGE AMOUNTS of biohazardous waste. Or at least you ought to be treating it like that, if you want to be an idiot, and think that a quarantine needs to occur with perfectly healthy individuals (who may become sick later).Report
I don’t have much of a problem with mandating a limited quarantine for health workers returning after having treated Ebola patients in Africa – indeed, it seems worth mentioning that MSF itself discourages its staff from returning to work within the 21 day period even though they take issue with the need for a complete quarantine. Where I take serious umbrage is the insistence that they essentially be arrested upon setting foot in the US and forced to go to a hospital. Especially given what we know about the epidemiology, why not allow them to at least stay at home and see family members provided that they be subjected to mandatory monitoring?Report
Mark,
these people are by definition not contagious. so why the fuck a quarantine?
I don’t think that it’s a good idea to further penalize these heros. They’re responsible people, that’s why they went there (I’m pretty sure banging the nurses is NOT A GOOD IDEA in this sort of epidemic…).
A quarantine for a virus that can spread with one virus intake to one human body, is one where you need biohazard treatment for everything. More than normal biohazard, too. It’s not something most houses are equipped for — and one that most hospitals don’t have procedures for (at least not automatically. that means untrained personnel)Report
@kim I’m just ambivalent about the notion of a limited quarantine – not supportive, but not passionately opposed either. Additionally, the problem isn’t about what they do while they’re asymptomatic. The problem is about where they are if they do become symptomatic. The NY doctor was not symptomatic when he went to the bowling alley, but he became symptomatic the next day, right? Well, what if he had become symptomatic a few hours earlier, while he was at the bowling alley?
Sure, the risk of transmission at that time would be incredibly small, which is why I’m not really supportive of this, but can we really say that it would be zero?
Again, MSF’s protocol itself indicates that returning volunteers should not go back to work within the incubation period, which means that if they follow the protocol, they’re time away from work is the same either way. And I’m sure everyone here is fully in favor of ensuring that they get reimbursed for that time away.
While it may not be the best policy, requiring that they stay at home for that period strikes me as being far from outrageous.Report
Mark,
I’m all in favor of government issued “quarantine gear” in case they do become symptomatic (to be carried with all potential Ebola victims until they pass the 3week mark). And a decently designed escort to the nearest quarantine-capable facility.
Keeping a person at home does you jack-all good if their bedding hits a laundromat, though. In a 3 week quarantine, that’s pretty likely.
(The “don’t work for a bit” seems pretty obvious. )Report
Mike,
Ebola is HIGHLY infectious, and VERY MUCH NOT contagious. If you know enough to not bleed/barf on someone else, you’re not really “walking around contagious.” This is NOT an airborne disease, unless you’re in the middle of very specific procedures.
We don’t quarantine AIDS patients (granted, that has a much higher threshhold for infection).Report
Also, this seems as good a place as any to share that Hannity recently wondered aloud about the possibility that a terrorist would go to West Africa, get ebola, and ride the American subway system until he keeled over.
Of course, when he said it, it sounded even more ridiculous.Report
“the American subway system”??Report
It doesn’t make it all the way to Alaska, Greg. But down here in the “real 48” you can take the subway from LA to NY, with stops in Las Vegas, Denver, Wichita, Chicago and Cleveland. It was _the_ shovel-ready project of the Great Recession.Report
The five-dollar footlong is a prominent disease vector. It is known.Report
Actually, it’s a germ-free substance, because even bacteria have standards.Report
The word you’re looking for here is “unhinged.”Report
“being anti-ebola was somehow conservative”
Let’s be serious here. We all know that 1) liberals hate America, 2) environmentalists want to depopulate the Earth, 3) Obama was born in Africa. Just connect the dots, sheeple!Report

Hmmm…considering that Tod name-checked “The Hot Zone” I suppose that’s an acceptably topical reference…Report
Couple things:
We kept hearing early on how Ebola could not be contracted via the airborne method, and that those health care workers MUST MUST have failed in their protection protocols. Then we also heard that these folks were not trained in the protocols. We also hear that it’s possible to contract Ebola from spit or other body fluids ejected from a sneeze or cough. Because the disease so rarely manifests that no one knows FOR SURE exactly how it’s transferred.
My first comment when the CDC guy was on tv saying that the nurses MUST have failed in following the protocols was “yah, you PROVED that or are you just speculating (and covering you ass)? And let’s not forget that the Dallas hospital wasn’t a NIH level 4 biohazard facility that is used to handling weird nasty bugs like Ebola.
I see no reason NOT to have health care workers quarantined after a stint tending to infected folks, here or there….just in case. Will it impact HC workers by limiting the number that go over? Maybe. But wouldn’t you want to be sure you weren’t infected before exposing your co workers when you came back?Report
No, not really. Ebola is like AIDS. If you aren’t dropping blood/vomit/sneezing around, you’re fine.
(protocols do include facemask, by the way).
We already have procedures for children with influenza in the hospital. They wear a facemask. If that’s all it takes to avoid contamination, quarantine is called massively overdoing it.Report
Yes because it’s been PROVED that Ebola isn’t transferred that way. Statistically significantly proved. Post the peer reviewed article.

“Dr. Beutler, an American medical doctor and researcher, won the Nobel Prize for Medicine and Physiology in 2011 for his work researching the cellular subsystem of the body’s overall immune system — the part of it that defends the body from infection by other organisms, like Ebola.
He is currently the Director of the Center for the Genetics of Host Defense at the University of Texas Southwestern Medical Center in Dallas — the first U.S. city to treat an Ebola patient and also the first to watch one die from the virus. In an exclusive interview with NJ Advance Media, Beutler reviewed Christie’s new policy of mandatory quarantine for all health care workers exposed to Ebola, and declared: ….
“I favor it, because it’s not entirely clear that they can’t transmit the disease,” Beutler said, referring to asymptomatic healthcare workers like Kaci Hickox, a Doctors Without Borders nurse returning from treating Ebola patients in Sierra Leone who was quarantined in New Jersey for 65 hours before being transported to her home state of Maine on Monday
afternoon. ”
Color me unconvinced you’re correctReport
Damon,
your article proves my point. We don’t quarantine people with AIDS, we don’t need to quarantine people who may have Ebola. (we take reasonable precautions. if they encounter the health system, they’re going to get quarantined)
I’ll take it as a given (for now) that your articles are a bit better than what the CDC is putting out. They’re still talking about STD level transmission from infected but not feverish individuals.
NJ.com isn’t talking about either the adaptive or the innate portion of the immune system, so color me skeptical that he’s actually done research on this damn thing, until you cite a scientific source.
You’re still missing my point — we have an incipient disaster on our hands — that website you’re linking — nuke it with fire? Sure, we need those vaccines stat.
But don’t miss the point that the contaminated bedding, silverware, towels are the REAL issue, not just “keep person in house and you win.” We don’t really have the procedures in place to deal with viruses that spread by single virus intake. And we need them, because this will generate massive volumes of “possibly contaminated stuff” that you can’t just bury.Report
Actually KIM, my point is it’s not known for sure that ebola cannot be transmitted by non personal contact with fluids, and there is evidence that it is. That alone makes a lot of what the CDC (the very guys who are supposed to KNOW) dubious.
Read the quote I posted. The guy is recommending quarantine.Report
Damon,
A duckbill facemask (what you’re calling a respirator) can be provided to someone without using a quarantine — and is standard CDC approved procedure for if someone’s vomiting/etc. Facemasks are cheap. EFFECTIVE QUARANTINE is not (see logistical issues with biohazards). You want anyone who is quarantined for this disease in particular to be at a safe biohazard disposal place.
“The Lancet study does not warn of an apocalyptic scenario where any casual contact could cause infection. It is more focused on contagion through sex or blood transfusions.”Report
I’m just going to give up now….Report
Jersey didn’t release the nurse as much as they were bullied into it by the Obama admin. At the same time the Army is going to quarantine all the troops that serve over there in our efforts to help.Report
Why Ebola has anything to do with tribal politics is beyond me. But then again I have only personally met a couple other classic liberals (that I know of) through my entire life. If I had a libertarian tribal meeting at my house I would be the total population.Report
Principled politicians would have come up with a decent plan (even if it included quarantine) months before now. If you only start taking action after something gets to the USA, when something getting to the USA was a completely predictable occurrence…. you’re succumbing to hysteria.
