Lead researcher Bert Blocken, Ph.D., of Eindhoven University of Technology, said in a Twitter response that they rushed to share findings because this crisis is a world-wide, urgent situation where people are dying and economies are crumbling.

In other words, the researchers are saying they have this concept they believe to be accurate, but they haven’t had it validated or peer-reviewed yet. These validation studies will be reported in the peer‐reviewed scientific publication to appear later.” In the researchers’ own words: “CFD simulations were performed with Ansys Fluent CFD, based on foregoing intensive validation studies for gas and particle releases at different speed around full‐scale manikins representing human bodies. The problem is that none of this is actually validated, including the CFD simulation itself. They concluded that being in someone’s slipstream-even within the currently recommended six-foot distance-is risky because of the “droplet cloud” they leave behind. Still, using the animated models and figures generally used to understand the benefits of drafting (riding or running in the slipstream of someone in front of you) for improving performance in elite athletes, the researchers used a computational fluid dynamics (CFD) model to simulate the release of saliva particles from persons walking or running in different configurations to see how many large and small droplets might be left in their wake. Think of it as experts double-checking other experts’ work. The reason peer review is so important is that it enforces the high standards of the scientific method and ensures that unwarranted claims, false conclusions, unacceptable interpretations, or personal views are not published without prior expert review. What You Need to Know About Spit and Snot During the Coronavirus Outbreak This is essentially a “ white paper,” a position paper written by someone with authority on a topic-in this case, a team of engineers and sports aerodynamic researchers from Belgium and the Netherlands-but not a peer-reviewed paper or even a non-peer-reviewed study.

But here’s why you should not let this new article rattle you.

To be clear, COVID-19 is extremely serious, and we firmly agree that everyone should run and ride solo, leaving the currently recommend six feet of physical distance between yourself and others plus more when you can. And it’s important to take both of those factors seriously right now before potentially spreading what could be misinformation. This paper is not a vetted study nor a study on disease transmission. But take a deep, socially-distanced breath.

In some areas, this is not even possible. It’s super easy to get freaked out when you’re now learning that you need to stay upwards of 32 feet away from a runner and 65 feet away from a cyclist in front of you. 'If you want to overtake someone, it is also recommended to start 'pre‐sorting' into a staggered arrangement from a fairly long distance -twenty meters with bicycles, for example, so that you can overtake carefully and at a proper distance by moving in a straight line.' Compare it to driving: if you want to overtake, you should also not wait until the very last moment.

The article Belgian-Dutch Study: Why in times of COVID-19 you can not walk/run/bike close to each other published on Medium, a free public platform that allows anyone to publish and doesn’t require fact-checking, has spread like wildfire across social media, with people zeroing in on both the paper’s title and conclusion: Keep a distance of at least four to five meters behind the leading person while walking in the slipstream, ten meters when running or cycling slowly and at least twenty meters when cycling fast. Days later, the authors published a more fully-detailed, non-peer-reviewed white paper, which no longer included cycling in the title and no longer included specific cycling recommendations.īy now, you’ve likely seen the Belgian-Dutch “study” on how virtual aerodynamics simulations show that we need to be running and riding a lot further away from each other during this COVID-19 pandemic.

It included no citations or details of their methodology.
