Coronavirus can spread as aerosol ‘beyond any reasonable doubt,' over 200 scientists tell the World Health Organization

In a letter published this week in the journal Clinical Infectious Diseases, 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." That means people in certain indoor conditions could be at greater risk of being infected than was previously thought.

... The letter was endorsed by 239 scientists from a variety of fields. It stated that the issue of whether or not COVID-19 was airborne was of "heightened significance" as many countries stop restrictive lockdown measures.
