2/ "In a 4-page letter addressed to White House COVID response chief, @CDCgov Director @RWalensky & Acting Labor Sec. Al Stewart, 4 House committee chairs say they have "serious questions" about the adequacy of the CDC's guidance on workplace protection from aerosol transmission"

3/ "For the last two weeks, scientists, experts and unions have been prodding the administration to be more specific about guidance on exposure to small aerosol particles that carry COVID-19, which they say the CDC's official guidelines downplay."

4/ "A dozen doctors & experts detailed their concerns in a letter in mid-February to the Biden administration. "For many months it has been clear that transmission through inhalation of small aerosol particles is an important and significant mode of SARS-CoV-2 virus transmission"

5/ "Numerous studies have demonstrated that aerosols produced thru breathing, talking, & singing are concentrated close to infected person, can remain in air & viable for long periods of time & travel long distances in a room & sometimes farther"
