Coronavirus Conundrums

now-and-then updates about the SARS-CoV-2 pandemic, with a focus on the U.S. and South Africa

I am Allison Ruark, a social epidemiologist and researcher who teaches epidemiology and public health as Assistant Professor at Wheaton College (Wheaton, Illinois, USA). I have a PhD (2015) from Johns Hopkins Bloomberg School of Public Health. In mid-March, I started tracking the novel coronavirus (SARS-CoV-2) in South Africa (where I was living at the time) and the United States (my home country), comparing those epidemics to Italy’s older epidemic as a kind of point of reference. I started posting those data visualizations and other thoughts and observations to Facebook, and soon had hundreds of people following the posts. I've started this blog as a way to more easily incorporate other visualizations and make the information more accessible. I am truly glad that I can help other people make sense of this pandemic during this challenging, unprecedented time. I welcome your comments but can't always respond as promptly as I would like. All views expressed are my own. Please let me know if you notice errors. Eventually I hope to migrate all content to this site, but for now you can view past posts at facebook.com/allison.ruark.
