NST Leader: Covid-19, airborne?

IF scientists are right, face masks may move from masquerades to mainstream. According to a Queensland University of Technology post yesterday, 239 scientists from around the world, led by its air quality and health expert Professor Lidia Morawska, say overwhelming research findings point to airborne transmission of Covid-19.

In a letter titled "It is Time to Address Airborne Transmission of Covid-19" to be published this week in the Clinical Infectious Diseases journal, they call on the international health authorities "to recognise and mitigate airborne transmission of Covid-19". It is no ordinary letter.

It's a plea, and there is a reason why the letter comes dressed as such. The World Health Organisation (WHO) is heavy on droplets and close contacts and less so on aerosol transmission.
