Nonpharmaceutical Measures for Pandemic Influenza in Nonhealthcare Settings—Personal Protective and Environmental Measures – Volume 26, Number 5—May 2020 – Emerging Infectious Diseases journal – CDC

For A Person Trying To Make Sense Of Efficacy, Xiao Presents The Most Useful Face Mask Research Of 2020 

Xiao in the May 2020 issue of Emerging Infectious Disease is the best study of the year on the topic. For those interested in delving deeper, I address that topic further in a recent article entitled “Reminder: The CDC Says Face Masks Don’t Stop Covid.” I cover the same topic in greater detail in my recent book . I strongly recommend Xiao’s journal article.

Emerging Infectious Disease is a CDC journal of epidemiology. Attempting to avoid lip service or the lure of political correctness, Xiao and her co-authors looked at Covid as a serious concern and sought to distinguish superstition from efficacious approaches.

In Xiao’s Emerging Infectious Disease review of 14 randomized controlled trials with laboratory confirmed results, we see quite conclusively that

• 1.) Face masks do not reduce the spread of Covid-19 or other respiratory viruses,

• 2.) Hand washing does not reduce the spread of Covid-19 or other respiratory viruses, and

• 3.) Disinfecting surfaces does not reduce the spread of Covid-19 or other respiratory viruses.
