But what is a “Highly Infectious Person?” For example, in Daegu, South Korea, just one woman, dubbed Patient 31, generated more than 5,000 known cases in a megachurch cluster.
According to Samuel Scarpino, an assistant professor of epidemiology and complex systems at Northeastern, COVID-19 spreads in clusters, unlike the flu which spreads in a more linear fashion. In study after study, we see that super-spreading clusters of COVID-19 almost overwhelmingly occur in poorly ventilated, indoor environments where many people congregate over time—weddings, churches, choirs, gyms, funerals, restaurants, and such—especially when there is loud talking or singing without masks.
This post contains quotes from the following article, which is several pages long and delves into the science of epidemiology. We chose to draw out a few key points which might be helpful to our friends.
