It's been just 1 incubation period since universal mask use, too soon to see its full impact but the speed of transmission has slowed. Melbourne it will improve ❤️ Look outside aged care facilities for change in community spread.
The built environment of age care facilities with COVID-19 positive residents is problematic. There is no ability to provide negative air pressure rooms, plus HEPA filters, plus air change of 40-80L/s/patient.
Airflow is a problem for older hospitals, @annecreaton@DrPieterPeach. The built environment of age care facilities with COVID-19 positive residents is problematic as there is no ability to provide neg air pressure rooms plus HEPA filters plus air change of 40-80L/s/patient.
OK regraphed NSW with today's data for yesterday. NSW reaching critical position & geographic spread makes it hard to find hotspot locations for ring-fencing/lockdown. Please follow public health rules & please mask up.
Yes, it shows NSW is on a knife edge. Victoria, I think, is coming out of their spike. But- Vic health workers must be mindful and wear a mask in every ward, as their infection numbers are of concern.
