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.

love film festivals, all of you could wear a mask (put it on with clean hands before you enter the venue) and enjoy.

"I know this will be criticised because it's across a wide geographical area, but that's the point." As cases in NSW rise, Sydney should make it compulsory to wear a mask to stem the outbreak, says @UNSW Epidemiologist & @WHO advisor, @MarylouiseMcla1. abc.net.au/news/2020-07-21/c…
