There is growing evidence that the virus may be more airborne than simply respiratory droplets, but this is still an area of research with many unanswered questions.
Nope. Aerosols were touted as being too small for simple cloth masks early on in the piece.
"In
April a scientific panel sent a letter to the White House saying that “studies are consistent with aerosolization from normal breathing.”2
"In
July two scientists published a commentary in Clinical Infectious Diseases saying it was time “to recognize the potential for airborne spread … There is significant potential for inhalation exposure to viruses in microscopic respiratory droplets (microdroplets) at short to medium distances (up to several meters, or room scale) and we are advocating for the use of preventive measures.”3
Two other scientists said in the Washington Post that the CDC was wrong and
that airborne transmission had been known for months. Joseph Allen from Harvard’s school of public health and Linsey Marr from Virginia Tech’s engineering department, wrote, “
Many scientists have known that airborne transmission of the virus was happening since February. The CDC somehow failed to recognize the accumulating evidence that airborne transmission is important and therefore failed to alert the public . . . When you talk or sing—or even just breathe—you emit a range of particles of different sizes.” Some particles are large and fall to the ground within 6 feet, but “there are also thousands of particles that are smaller than five microns. Such particles stay aloft for minutes to hours and can travel all the way across a room on natural air currents.”4.

CDC on cloth masks -
"Materials
Two 10”x6” rectangles of cotton fabric
Two 6” pieces of elastic (or rubber bands, string, cloth strips, or hair ties)
Needle and thread (or bobby pin)
Scissors
Sewing machine"

If you put this to him, I would expect nothing less than a condescending reply filled with pedantry and no real interest in clearing the air on the subject, he's usually nothing but a troll with a slightly better lexicon than your normal Trumptard.
Talk about lexiconese that says nothing. Talk about being slow. Known since February and still in draft form.
