This week, Brett Mitchell and Martin Kiernan are joined by Dr Kirsty Buising, infectious diseases physician at the Royal Melbourne Hospital who is also Deputy Director of the National Centre for Antimicrobial Stewardship and chief investigator for the National Health and Medical Research Council (NHMRC) funded Centre for Research Excellence in Antimicrobial Stewardship in the Doherty Institute at Melbourne University. Together they discuss a paper just published in Infection Control and Hospital Epidemiology in which small, domestic-level HEPA filtration devices were used to rapidly remove glycerine-based aerosol, used as a surrogate for respiratory viruses, from rooms and corridors in a hospital setting.This was an excellent example of a multi-disciplinary highly specialist team who drew on each other's strengths to work a a problem.
