SARS-CoV-2 survives longer on common surfaces than does SARS1. Many of us believe this aspect of #COVID19 remains under-appreciated. Today, the @CDCgov released a report documenting the possible high-risk for environmental transmission of this virus. 1/5 wwwnc.cdc.gov/eid/article/26…
This past spring, an experimental study published in @NEJM found that SARS-CoV-2 survives much longer on cardboard, stainless steal, and plastic than does SARS1. 2/5 nejm.org/doi/full/10.10…
Using these lab estimates--and a mathematical model fit to data from 17 different countries--Prof. Ogbunu (@big_data_kane) et al., found strong evidence for a role of environmental transmission in #COVID19 epi. 3/5 medrxiv.org/content/10.110…
As Prof. Ogbunu & his team @Yale point out, there are other models which are consistent with the epi patterns seen in these countries. However, given the increasing evidence for the role of environmental transmission in #COVID19, this is something we can't afford to ignore. 4/5
As a co-author on Prof. Ogbunu's pre-print, I'm biased. But, I'll also be the first to admit that, while we may end up being wrong about the importance of environmental transmission, the steady build-up of experimental, observational, & theoretical evidence cannot be ignored. 5/5
