Congratulations to the team at Addenbrookes Hospital, Cambridge, UK who have investigated the airborne risk from SARS-CoV-2 in two of their wards. Although still to be peer reviewed the work has generated some good data
Detection of airborne virus is a difficult process due to air samplers which can damage the target viruses
In addition to proving the presence of airborne SARS-CoV-2 the application of HEPA/UV in reducing the threat was also demonstrated
Addenbookes Conclusion
“Our data is highly indicative of aerosolised SARS-CoV-2 portable air filtration devices can mitigate the reduced availability of airborne infection in isolation facilities.
The use of such systems may provide additional safety for those that are of high exposure risk to respiratory pathogens such as SARS-CoV-2.”
