WHO: Indoor airborne spread of coronavirus possible
July 10, 2020
LONDON - The World Health Organization is acknowledging the possibility that COVID-19 might be spread in the air under certain conditions - after more than 200 scientists urged the agency to do so.
In an open letter published this week in a journal, two scientists from Australia and the U.S. wrote that studies have shown "beyond any reasonable doubt that viruses are released during exhalation, talking and coughing in microdroplets small enough to remain aloft in the air."
The researchers, along with more than 200 others, appealed for national and international authorities, including WHO, to adopt more stringent protective measures.
