| Sure thing. First, note that Eric Feigl-Ding is a nutritional epidemiologist, not an infectious disease epidemiologist. Infectious diseases are weird for a lot of reasons, and require something of a different skillset. For example, in a Tweet of his he has now deleted: "never seen an actual virality coefficient outside of Twitter in my entire career." about the estimate for R0 for this novel coronavirus. Similar R0 estimates existed for SARS, and MERS. Measles, Rubella and a number of other diseases have vastly higher R0s. He also messed up some things like conflating R0 with secondary attack rates, and was generally very sensationalistic. Basically, the things that boosted him to prominence in this epidemic built on fairly sloppy reasoning from someone outside the field. He's calmed down now, but one might as well go to sources for people who are both good at science communication and actual outbreak scientists. |
