1/5 #COVID19 key concerns 🇨🇦: this may feel like a double marathon we didn’t sign up for, but we can draw strength knowing the ground we’ve covered so far to stay on track and work together to get where we need to go.…
2/5 As public health continues vaccination efforts & closely monitors local epidemiology for signs of peaking activity in the weeks ahead, we can all help by staying the course to get through this difficult time sooner. #VaccinesPlus➡️…
3/5 Currently, we still need millions more Canadians to increase their protection with #COVID19Vaccines, including almost 7 million eligible people who need a 1st or 2nd dose of their primary series.

1/7 #COVID19 key concerns 🇨🇦 : COVID-19 cases have rapidly accelerated, with #Omicron now predominating and widespread across much of the country. The latest 7-day average of 40,696 cases/day is a 78% increase over last week.
2/7 Though very high activity levels that challenge testing capacity may underestimate true case numbers, other indicators remain useful to monitor trends in overall disease activity (e.g. test positivity) & severity (hospitalizations etc.)
3/7 Not surprisingly, as exponential growth of #Omicron continues, these trends are all rising; in the past most recent 7-days % lab test positivity increased by to 28%, while average daily hospital/ICU numbers increased by 82% and 20% respectively.

1/3 The same as vaccination provides us with an essential base layer of immune readiness and protection, face masks are an essential top layer to prevent or reduce virus inhalation and spread between people.…
2/3 Ensuring your mask is of the best construction and fit possible, can make that top or outer barrier layer of protection perform much better to seal out and filter out infectious particles that may be suspended in the air we breathe. #MaskFit

1/5 Layering #COVID19 protections is best! Evidence on aerosol spread of the #SARSCoV2 virus shows that expelled virus particles can spread over distances and linger in fine aerosols for periods of time, much like second-hand smoke.…
2/5 Likewise, those in close proximity to the infected person can inhale more aerosols. This is why opening a window can help reduce the risk and why wearing a well-fitted and well-constructed mask is so important. #GoodVentilation #MaskFit
3/ 5 Similar to how second-hand smoke can leave a room when a door or window is opened, improved ventilation can remove virus particles from the air.

A 🧵 to counter some confusing messages about masks & wildfire smoke (1/x)

1. High-quality masks (i.e. #N95) best for both viral aerosol + #wildfire smoke
2. N95s readily available & should be used for both
3. But other masks can provide non-zero benefit…
2/ The #CDC and #EPA both strongly recommend upgraded masks (respirators) like #N95 or #KN95 to protect against wildfire smoke. I totally agree (unless using something even better like N99 or elastomeric), b/c these filter the smallest particles very well.…
3/ But the #CDC also says not to use N95s, b/c they "should be reserved for health care workers." I totally disagree, as do countless others, b/c supply chain problems in 2020 have recovered in the US.
