‘A welcome step’: WHO acknowledges aerosol spread of COVID-19 But experts say the Australian Government’s infection control group must now update its advice to ensure new strategies to reduce transmission risks.
Guidelines questioned as research highlights COVID aerosol threat Coughing can create 100 times more aerosol particles than oxygen therapies, increasing risk for healthcare workers who wear surgical masks.
Another quarantine outbreak raises questions over airborne transmission The newly-confirmed coronavirus case is a Melbourne hotel worker branded a ‘model employee’, who did not breach any infection control protocols. So how did he catch the virus?
Masks can block 99.9% of COVID-linked droplets With face masks now mandatory in multiple settings, research shows they are ‘highly effective’ at reducing spread of respiratory droplets.

PPE debate continues as expert accuses authorities of following ‘false narratives’ One of Australia’s foremost infectious disease physicians says healthcare workers are being put at undue risk of coronavirus infection by current PPE guidelines.

WHO acknowledges COVID-19 airborne transmission may be possible Despite only recently pushing back against such claims, scientists from the global health body have now said there is emerging – but not definitive – evidence.
