Contagion Dynamics

Contagion Dynamics and the Economic Impact of COVID-19

 

Martin Pergler shares a couple of files on understanding COVID-19 contagion dynamics, and some of the tradeoffs of managing spread vs long term social/economic impact.

People seem to be increasingly internalizing and accepting efforts prudentially required to slow down COVID-19s exponential infection rates. And hopefully we’ll converge even more from the poles of “barricade ourselves behind hoarded toilet paper” and “what me worry, I don’t see a problem yet” behaviour. However, given differences in, and evolution over time of, testing and reporting around the world, we also need to get ahead of monitoring the evolution of the outbreak and its containment in different geographies. We’ve all seen the “buy time to flatten the curve” graphic many times by now, but I think we all hope we can minimize the area under the curve, not just flatten it.

With this in mind, I’m happy to see a paper on statistical time series modeling applied to localized contagion dynamics cross my desk, from Italy no less! Pretty technical in nature, and frankly there isn’t truly enough data to draw any actionable conclusions yet, but we’re going to need analysis of this type to be able to extrapolate sensibly going forward, and to judge to what extent containment approaches — including different intensities of social distancing — are working.
