(David Gilbert/ Vice) — Over 200 scientists in more than 30 countries say the coronavirus is airborne and that the World Health Organization is not doing nearly enough to address the issue.
In a letter entitled “It is Time to Address Airborne Transmission of Covid-19” the scientists lay out an argument many of them have been making for months: that coronavirus is not just spread through large droplets and direct contact with infected people, but also though microscopic particles that linger in the air indoors and infect those nearby when they inhale them into their lungs.
It means that crowded or poorly ventilated indoor settings such as bars, restaurants, casinos, schools, and offices are especially dangerous and would account for a number of “super spreading” incidents.
The letter is due to be published in the Clinical Infectious Diseases journal and is authored by Lidia Morawska, an expert in aerosol transmission at the Queensland University of Technology in Brisbane, and Donald Milton, a professor of environmental health at the University of Maryland. It has been endorsed by 239 scientists from 32 countries. (…)
