Canada, now that England has finally made face masks mandatory will Health Canada follow? No more excuses. @devisridhar global public health expert @EdinburghUni “The only real question about face masks is what took England so long?” #Masks4Canada@jkwan_md@robshirkey
Canada, sound familiar? Health Canada befuddled on mandatory masks. Global public health expert @devisridhar: “After going around in circles about the merits of face coverings for months, England has made them mandatory in shops from 24 July.” #Masks4Canada@jkwan_md@robshirkey
Canada’s MoH, PHAC, & CPHO are wrong on “slow burn”:
..of cases remains low enough for the public health care system to keep ahead of the influx of patients.”
“Slow burn” assumes you can control the virus, but you can’t. It’s a pandemic; the virus spreads easily. #Go2Zero 2/
Canada’s MoH, PHAC, & CPHO are wrong on “slow burn”:
It’s a pandemic of a dangerous virus that spreads easily. “Slow burn” so cases won’t overwhelm hospitals is pretty calculating.
Who says how many deaths or long-term illness? There is no acceptable number of cases. #Go2Zero 3/
Aerovirologist Lednicky & others (2020) “Collection of #covid19 from Air of a Clinic” find the virus in air 2+ m away from source. “Collection of a positive sample from a distance more than 2 m away from nearest patient traffic implies the virus was in an aerosol.” 2/ #cdnpoli
Aerovirologist Lednicky et al. (2020) found the virus in an aerosol over 2 m away was viable; clinic then changed its PPE protocol, requiring N95 masks for all its healthcare workers even if not working directly with #covid19 patients. #cdnpoli@janephilpott@jkwan_md
1/ Which is Canada’s Public Health’s #covid19 response? Wish it was zero transmission to save lives. #cdnpoli
Global PH expert @devisridhar: in UK one camp wants govt to try “get over the worst of the pandemic by allowing the virus to spread through the population..
2/ Which’s Canada? Global PH expert @devisridhar on what the first UK camp wants in #covid19 strategy: allow virus to spread: “..albeit at a slower pace to ease the strain on the NHS, and by creating more hospital and mortuary capacity to cope with a spike in deaths.” #cdnpoli
3/ Which’s Canada’s #covid19 response? Global PH expert @devisridhar on what the UK second camp wants in its #covid19 strategy: “reduce the rate of infection – or R – to as close to zero as possible. It recognises the uniquely dangerous nature of this virus..” #cdnpoli@jkwan_md
1/ Canada, science on masks for all clear some time ago.
Yet Canada’s Liberal Trudeau govt & supporters cite “changing science” for delay in mask advice. Perhaps science was ignored? #cdnpoli#covid19
Oxford @trishgreenhalgh & SFU @jeremyphoward summary: fast.ai/2020/04/13/mas…
2/ On April 13 @trishgreenhalgh & @jeremyphoward wrote on science of #Masks4All. Since virus R0 was estimated at 2.4 by Imperial College researchers, as high as 5.7 by others: “This means that without containment measures, #COVID19 will spread far and fast.” #cdnpoli
3/ In early April, Oxford @trishgreenhalgh & SFU @jeremyphoward wrote on science of #Masks4All: “Importantly, #COVID19 patients are most infectious in the early days of the disease.. during which they generally have few or no symptoms.” #cdnpoli
Canada #cdnpoli failed to implement early & wide testing for #covid19 because of Liberal MoH Patty Hajdu’s flawed risk assessment - ultimately political - the federal govt can “manage” the surge of the pandemic, ignoring best science advice, WHO. #covid19Canada @janephilpott
MoH Patty Hajdu’s flawed political risk assessment ignored best science advice on critical role of testing in #covid19 response, so the federal Liberal govt has not allocated enough funds for testing rapidly & broadly, including mild illness, no travel. #cdnpoli#covid19canada
The federal Liberal government needs a radical change in a political-based risk assessment of the importance of rapid & broad testing in its #covid19 response to provide enough funding now, in days, not weeks. #covid19canada#cdnpoli
