The World Health Organization (WHO) are currently looking into new research findings that Covid-19 could possibly be an airborne threat in areas of poor ventilation. A report compiled by the University of Colorado has provided evidence that the coronavirus can be spread by tiny particles suspended in the air.

One signatory of the report, Professor Benjamin Cowling of Hong Kong University stated: “In healthcare settings, if aerosol transmission poses a risk then we understand healthcare workers should really be wearing the best possible preventive equipment… and actually the World Health Organization said that one of the reasons they were not keen to talk about aerosol transmission of Covid-19 is because there’s not a sufficient number of these kind of specialised masks for many parts of the world.”

“In the community, if we’re thinking about aerosol transmission being a particular risk, then we need to think about how to prevent larger super spreading events, larger outbreaks and those occur in indoor environments with poor ventilation, with crowding and with prolonged close contact.”

WHO officials have cautioned the evidence is preliminary and requires further assessment.

Benedetta Allegranzi, the WHO’s technical lead for infection prevention and control, said that evidence emerging of airborne transmission of the coronavirus in “crowded, closed, poorly ventilated settings that have been described, cannot be ruled out“.

Allegranzi also went on to say, “Inhaling small airborne droplets is probable as a third route of infection, in addition to more widely recognized transmission via larger respiratory droplets and direct contact with infected people or contaminated surfaces.” And that “Appropriate building engineering controls include sufficient and effective ventilation, possibly enhanced by particle filtration and air disinfection, avoiding air recirculation and avoiding overcrowding” will significantly reduce the risk posed.


CHANNEL Facilities Management Ltd’s continuing use of the Covid-Guard cleaning product to sanitise all of the surfaces within our client’s properties and our fogging service which utilises the Z-71 product are already tackling the airborne risk head-on.
Both of these products linger in the air and encapsulate and destroy the virus particles, therefore stopping the spread.
