More proof of airborne transmission - the case of the Diamond Princess cruise ship
"A computer model of the cruise-ship outbreak found that the virus spread most readily in microscopic droplets light enough to linger in the air."

"On Jan. 20, one infected passenger boarded the cruise ship; a month later, more than 700 of the 3,711 passengers &crew members had tested positive, with many falling seriously ill..Ever since, scientists have tried to pin down exactly how the coronavirus spread through the ship"
"The Diamond Princess’ outbreak remains perhaps the most valuable case study available of coronavirus transmission.
..Now, researchers are beginning to use macroscopic tools — computer models, which have revealed patterns in the virus’s global spread"

*Key finding*
"In a new report, a research team based at Harvard & the Illinois Institute of Technology has..found that the virus spread most readily in microscopic droplets that were light enough to float in the air, for several minutes or much longer."

"The new findings add to an escalating debate among doctors, scientists & health officials about the primary routes of coronavirus transmission. Earlier this month..the WHO acknowledged that the virus could linger in the air indoors, potentially causing new infections."

"The new findings, if confirmed, would have major implications for making indoor spaces safer and choosing among a panoply of personal protective gear."

"For example, ventilation systems that “turn over” or replace the air in a room or building as often as possible, preferably drawing on external air to do so, should make indoor spaces healthier. But good ventilation is not enough..."
"...wearing good-quality masks — standard surgical masks, or cloth masks with multiple layers rather than just one — will most likely be needed as well, even in well-ventilated spaces where people are keeping their distance."

"The computer modeling adds a new dimension of support to an accumulating body of evidence implicating small, airborne droplets in multiple outbreaks, including at a Chinese restaurant, a choir in Washington State..a recent study at a Nebraska hospital"

"One researcher not involved in the new work, Julian Tang..associate professor of respiratory sciences..said the paper was “the first attempt..to formally compare the different routes of coronavirus transmission, especially of short versus long-range aerosols.”

"The new analysis..led by Parham Azimi, an indoor-air researcher at Harvard’s T.H. Chan School of Public Health, studied the outbreak...where physical spaces & infections were well documented..[They ran] >20,000 simulations of how the virus might have spread throughout the ship."
"About 130 of those simulations reproduced, to some extent, what actually happened on the Diamond Princess...By analyzing these most “realistic” scenarios, the research team calculated the most likely contributions of each route of transmission."

*Key Finding re reopening schools*
"The researchers concluded that the smaller droplets predominated, and accounted for about 60% of new infections over all, both at close range, within a few yards of an infectious person, and at greater distances."

"The smaller droplets are..more likely to penetrate deeply into the respiratory system, down to the lungs. It may take a much smaller viral load..to cause infection in the lungs than higher up, such as in the throat. This,at least, is the case for other respiratory viruses"
"Brent Stephens, an engineering professor..& a co-author on the paper..said the findings were important in shaping..measures that should be taken as college students return to campus.
The first, he said, should be “really enforcing mask policies.”

"As various transmission routes come into clearer focus, they will provide specific guidelines on how to reopen schools, offices, restaurants and other businesses."
