Yesterday I ran a poll asking if people could create a simulated dataset showing confounding (traditional change in estimate definition). Here’s why it matters to me and how I approach it, a thread 1/14
To me it matters that my students can do this because it gets to a fundamental understanding of what confounding looks like (or can look like) in data 2/14

I was supposed to give a talk earlier this year for which I made these fake epidemiologic kids books. I didn’t get to give the talk live and could only use part of them, so I’m sharing here. Enjoy.

Until we are through with this (hopefully) last severe part of the epidemic and the vaccine is in wide use, I encourage you to think in terms of population risk unless you are exposed or infected and then switch to thinking about population risk. Let me explain…
Your individual risk of being infected and experiencing severe disease may be low. You may be young and healthy. It’s natural to think you may want to take risks because the risk of getting infected to you, is low. That’s individual risk.

That 2/3 of people in hospital in NY with COVID were distancing is totally to be expected and doesn’t mean distancing isn’t working. The reaction is understandable, but misleading, and this is why epidemiology is not “applied common sense”. A thread. 1/10

When the majority of people are staying home, we should expect that most of the transmission that is occurring will be among people who are staying at home. 2/10

Physical distancing is getting better, but some still seem not to be following. Given that, here are some thoughts about the difference between individual risk vs group risk and why it matters for an infectious disease outbreak. #covid#epitwitter 1/6
Many people I encounter still seem to be doing the personal math on risk. They reason, not many (known) cases in my area, so the risk to me is currently low. I won’t engage in high risk behaviors like being in large groups, but small groups is fine. #covid#epitwitter 2/6
