Partial good news out of @CDCgov today. cdc.gov/coronavirus/20…
Recognition that fomites are a minor route, and stop the #hygienetheatre . Also good, and pathbreaking that they cite #QMRA studies in support. 1/N

Interesting that they use a 1/10,000 from a surface contact as being indicative of low risk from fomites (many of us have seen that number before). But, still some problems in this updated science brief. 2/N
Opening sentence: "The principal mode by which people are infected with SARS-CoV-2 (the virus that causes COVID-19) is through exposure to respiratory droplets carrying infectious virus." While they don't use the word #aerosol in the body 3/N
The fallacy of #fomites.
There has been a lot of attention devoted to the potential transmission of #COVID19 by fomites, a lot of money and time spent on "sanitizing" surfaces, and on marketing various chemicals, treatments, etc. 1/N

While generically, cleanliness is good, I am convinced that the vast amount of these efforts when targeted at #COVID19 are misguided and represent more #hygienetheatre than true prevention. 2/N
First, I have yet to see any reports of transmission that convincingly demonstrate a fomite route (as opposed to a couple of cases reports that allege this as a diagnosis of exclusison, while failing to consider more plausible routes such as aerosols). 3/N
