Which year saw the most deaths from Covid in Canada?
#WearAMask #BetterMasks #COVIDIsAirborne #CovidIsntOver #CovidIsNotOver #DoAllTheThings
Wear the best mask available
The best mask is an N95
Actually the most effective respirator at a reasonable price is an elastomeric N100 or P100.
95 - >95% efficient at .3u
99 - >99% efficient at .3u
100 - >99.97% efficient at .3u
N = not oil resistant
R = somewhat oil resistant
P = oil resistant
@Pat We don't promote those over N95s because in the community people are wearing #bettermasks and #n95s without fit testing, where we have data to show results in >90% fitted filtration efficiency in most.
AFAIK, not known if we get additional gains from N99 or elastomerics without fit testing - let me know if you have a reference on this.
For others reading this, the numbers @Pat is quoting are for the masks tested on a machine, glued to a plate around the edges. Fit testing N95s on people in occupational health and safety protocols require >99% protection as fitted filtration efficiency (ie, fit factor >=100). A large proportion of people will achieve this, particularly with novel designs of #BetterMasks like Vitacore's CaN99 and the 3M Aura. Average filtration not-fit-tested is usually reported >90% in lab studies. Studies summarized at https://maskevidence.org/mask-types

Deaths per million in Canada:
Canada has a population of about 38 million, so this translates into 18,700 deaths from Covid in Canada in 2022.
For 2023, as far as we know for now, suggests a similar death rate this year.
IHME predicts that 80% mask use in public spaces (ie, a mask mandate) would reduce deaths by two-thirds within 2 months. That's 12,500 preventable deaths in Canada, over the course of a year. Much more in larger countries or countries with higher current death rates.
