Affiliate Zack Almquist Co-authors Study on COVID-19 Timing and Severity

Posted: 9/15/2020 (CSDE Research)

CSDE Affiliate Zack Almquist, along with coauthors, recently published an article in PNAS examining the impact of an uneven population distribution on the spread of the COVID-19 disease spread. Employing a diffusion model based on interpersonal contact networks, they assess the effect of employing more geographically detailed diffusion models based on known spatial features of interpersonal networks. They find that disease diffusion occurs via a long-tailed but monotone decline in the probability of interaction with distance. They conclude that spatial heterogeneity may produce dramatic differences in social exposures to those with the illness and may stress health care delivery systems in ways that are not well captured by standard infectious disease models. To read the article click here
