Australian epidemiologist Tony Blakely has called for tighter hotel quarantine restriction protocols after new evidence pointed to a resident's nebuliser as the potential culprit of the recent Holiday Inn cluster.
A new graphic produced by Channel Seven explains how the Covid-positive guest could have spread virus particles to the hotel's corridor after using the medical device in their room.
"We will see more cases I suspect, hopefully just from people who were in the corridor and not out in the community," professor Blakely told Sunrise this morning.
"One thing I've noticed is we've identified the contact spots just two days after people have been there, so things have been happening very quickly on the contact tracing.
"But back to the nebuliser itself. It highlights the importance of aerosol transmission, and it might be the kick in the pants we need to improve our quarantine system." A nebuliser is a drug delivery device used to administer medication in the form of a mist inhaled into the lungs.
Epidemiologist @TonyBlakely_PI says hotel quarantine needs to be "tightened" after it was revealed a nebuliser may have spread COVID-19 in Melbourne's Holiday Inn.

48 residents at the Holiday Inn have been evacuated as authorities undergo terminal cleaning.
Victorian health officials sent out a new public warning on Wednesday night, urging anybody who was at the Sunbury Square Shopping Centre between 3:40pm and 4:30pm last Friday to get a Covid-19 test.
The Department said it was “taking a precautionary approach” after a number of businesses inside the centre were listed as exposure sites.
