The CDC Director Robert Redfield is stepping up the #COVID19 propaganda on masks & social distancing ignoring the science published on this topic prior to the COVID hype (see: https://aapsonline.org/mask-facts/ ).
Note that he's intensely reading off of a Script instead of speaking his mind! https://twitter.com/CDCDirector/status/1288958678717136897
Redfield even ignores published meta-analyses of Randomized Control Trials featured on the CDC website such as Xiao et al (2020: https://wwwnc.cdc.gov/eid/article/26/5/19-0994_article), who found that face masks & hand washing had no "substantial effect on transmission of laboratory-confirmed influenza".
Here is an example of a politically tainted self-contradicting JUNK science on masks published in 2020:

Chughtai et al (2020: https://wwwnc.cdc.gov/eid/article/26/5/19-0994_article) state that cloth masks do not offer protection to healthcare workers, but should be worn by people in community settings!
