Many long hours late into the work day; but I feel at the “top of my game” :)

The logic we knew. Aged Care Residential facilities not purposed built to or "proxy hospitals" to care for COVID-19 residents. "Long-Term Care Facilities as a Risk Factor for Death Due to COVID-19" Gandal N.

Victoria has registered its seventh consecutive day of double-digit coronavirus cases as NSW Premier Gladys Berejiklian warns businesses not to interact with citizens from Melbourne. But could this COVID-19 spike have been avoided? @MarylouiseMcla1 explains. #TheLatest #7NEWS

That’s a lot of droplets in the air but at least he’s at home :)
Three layers to the mask- water repellent material on outside; middle layer- polyester; and the side facing your mouth-breathable close weave cotton (e.g. Quilters cotton).

“There are 3 things happening in Victoria. One is a community outbreak & that's quite complex & I think that it's about 28% ... There's about 21% related to travellers coming back … Then there's health provision & that's about 14%.” - Prof @MarylouiseMcla1, @UNSW #abc730

Victoria has recorded five consecutive days with new #COVID19 infections - and cases are likely to continue to rise if extra precautions, like wearing face masks, aren’t taken in virus hot spots, says @UNSWMedicine's Prof @MarylouiseMcla1. 😷3aw.com.au/melburnians-urged…

Online best option unless we get a single centralised quarantine location with experts in environmental cleaning, high air changes (unlike hotel rooms with sealed windows) to reduce secondary cases into community via quarantine hotel staff (thinking Victoria’s large cluster).

Youre mistaking management of an outbreak to be confined only to numbers. Management includes reducing community fear, and responding to lifting of restrictions when community spread is continuing even at low numbers.

cloth masks can’t provide medical grade mask protection and medical masks are in short supply globally. Not surprising WHO want to offer community some protection rather than none but you personally dont have to choose.

I don’t think you understand the issues.

We are in uncharted territory- lifting restrictions without 0 cases over 2 incubation periods. 😷Low but persistent cases in NSW & Victoria. 😷Wear a good, 3 layer home made mask & keep the mouth shut wearing it, to reduce chance of infection by up to 70%.tinyurl.com/y8llm7e3

You can achieve between 10-70% depending on quality. The WHO recommends cloth mask with 3 layers and this should provide protection towards the higher end of this range.

Commuters and close contact workers- if you wear a good, 3 layer home made mask AND keep your mouth shut while you wear it, you’ll reduce chance of infection by up to 70%. For latest @WHO mask info- tinyurl.com/y8llm7e3 #COVID19 #WearAMask
