What’s coming: An epidemiologist speaks plainly

,
Northeast MS news Plain speaking about social distancing

“This virus is unforgiving to unwise choices.”

–Dr. Jonathan Smith

 

Editor’s Note: Yesterday evening (Saturday) we observed clusters of people in Northeast Mississippi neighborhoods and other public places, standing around in groups shoulder-to-shoulder, openly ignoring social distancing guidelines. Although everybody from the president on down has been warning against such irresponsible behavior for many days, it’s still going on. If these ignorant people were endangering only themselves, we’d be inclined to ignore it.

That is not the case. Everyone of us is threatened by their behavior.

Dr. Jonathan Smith, a nationally esteemed epidemiologist at the Yale University’s School of Public Health, published the following open letter two days ago. Dr. Smith explains very clearly what social distancing really means. It is written in simple words, short sentences, is not very long, and any minimally literate person will be able read and understand it. We have little hope that many of those we saw thus grouped together will be able to read and grasp what Dr. Smith says. However, the regular readers of NEMISS.NEWS will have no trouble with it. Perhaps some of them will phone local law enforcement if they observe such idiocy in future days.

 

Dear everyone,

As an infectious disease epidemiologist, at this point I feel morally obligated to provide some information on what we are seeing from a transmission dynamic perspective and how they apply to the social distancing measures.

Like any good scientist I have noticed two things that are either not articulated or not present in the “literature” of social media.

Specifically, I want to make two aspects of these measures very clear and unambiguous.

First, we are in the very infancy of this epidemic’s trajectory. That means even with these measures we will see cases and deaths continue to rise globally, nationally, and in our own communities in the coming weeks.

Our hospitals will be overwhelmed, and people will die that didn’t have to.

This may lead some people to think that the social distancing
measures are not working.

They are.

They may feel futile.

They aren’t.

You will feel discouraged.

You should.

This is normal in chaos. But, this is also normal epidemic trajectory.

Stay calm.

This enemy that we are facing is very good at what it does; we are not failing. We need everyone to hold the line as the epidemic inevitably gets worse.

This is not my opinion; this is the unforgiving math of epidemics for which I and my colleagues have dedicated our lives to understanding with great nuance, and this disease is no exception.

We know what will happen; I want to help the community brace for this impact.

Stay strong and with solidarity knowing with absolute certainty that what you are doing is saving lives, even as people begin getting sick and dying.

You may feel like giving in.

Don’t.

Second, although social distancing measures have been (at least temporarily) well-received, there is an obvious-but-overlooked phenomenon when considering groups (i.e. families) in transmission dynamics.

While social distancing decreases contact with members of society, it of course increases your contacts with group (i.e. family) members. This small and obvious fact has surprisingly profound implications on disease transmission dynamics.

Study after study demonstrates that, even if there is only a little bit of connection between groups (i.e. social dinners, playdates/playgrounds, etc.), the epidemic trajectory isn’t much different than if there was no measure in place. The same underlying fundamentals of disease transmission apply, and the result is that the community is left with all of the social and economic disruption, but very little public health benefit.

You should perceive your entire family to function as a single individual unit; if one person puts themselves at risk, everyone in the unit is at risk.

Seemingly small social chains get large and complex with alarming speed.

If your son visits his girlfriend, and you later sneak over for coffee with a neighbor, your neighbor is now connected to the infected office worker that your son’s girlfriend’s mother shook hands with.

This sounds silly, it’s not.

This is not a joke or a hypothetical.

We as epidemiologists see it borne out in the data time and time again, and no one listens.

Conversely, any break in that chain breaks disease transmission along that chain.

In contrast to hand-washing and other personal measures, social distancing measures are not about individuals, they are about societies working in unison.

These measures also take a long time to see the results.

This enemy that we are facing is very good at what it does; we are not failing. –Epidemiologist Jonathan Smith, MD
It is hard (even for me) to conceptualize how ‘one quick little get together’ can undermine the entire framework of a public health intervention, but it does.

I promise you it does.

I promise. I promise. I promise.

You can’t cheat it. People are already itching to cheat on the social distancing precautions just a “little”- a playdate, a haircut, or picking up a needless item at the store, etc.

From a transmission dynamics standpoint, this very quickly recreates a highly connected social network that undermines all of the work the community has done so far.

Until we get a viable vaccine, this unprecedented outbreak will not be overcome in grand, sweeping gesture, rather only by the collection of individual choices our community makes in the coming months.

This virus is unforgiving to unwise choices.

My goal in writing this is to prevent communities from getting ‘sucker-punched’ by what the epidemiological community knows will happen in the coming weeks.

It will be easy to be drawn to the idea that what we are doing isn’t working and become paralyzed by fear, or to ‘cheat’ a little bit in the coming weeks.

By knowing what to expect, and knowing the importance of maintaining these measures, my hope is to encourage continued community spirit, strategizing, and action to persevere in this time of uncertainty.

    Though I agree wholeheartedly with the prefaced editor’s comment, it serves only to boost those like me – who already agree. It would be an automatic turn off for anyone who may be making the grave mistakes described. What, then, is the purpose of sharing these wise words if you start off with condescending marks that risk those who took the step and clicked the article to learn more going straight to the X on their window? If you truly seek to change minds, something I believe to be critical at this time, save the derogatory comments for …well, the comments. Allow people who are making these mistakes to read this perspective without first feeling completely alienated and angered by your editor’s notes.
