And the N95 masks are expensive! Can we claim these on our PDR ?

“Be kind, be calm and stay safe” -Dr. Bonnie Henry, BC Provincial Health Officer From: Lyn Bartram <lyn@sfu.ca> CBC MArletplace did a story on the KN95 masks that met 94-95% filtration standars. Here is the link: https://www.cbc.ca/news/canada/mask-filtration-standards-marketplace-1.5974442 apparently we can order N95 masks through facilities

“Be kind, be calm and stay safe” -Dr. Bonnie Henry, BC Provincial Health Officer From: Ronda Arab <ronda_arab@sfu.ca> Hi Lucas, Where are you buying the N95 masks? I have some from Canada Strong, but they are completely out of stock and I'd like to get more for teaching and taking public transit to campus. I did
find a box of K95 masks that were made in China (and very cheap) but not all of those masks meet the safety standards and there is no way for me to know if they ones I got do. Also, they are really too big for my face, so aren't really very good. If you have a lead on where to get them, preferably Canadian made ones, I'd be super grateful! Best, Ronda Dr. Ronda Arab Associate Professor of English Simon Fraser University pronouns: she/her From: Lucas Herrenbrueck <herrenbrueck@sfu.ca> So great to see everyone here again. Happy New Year! Anthony: I also applaud SFU's commitment to experimentation!
It's the purest form of science. Nicky: I'm afraid "transmission has been observed to occur in households and unstructured social settings... structured settings... have a lower risk for transmission" is a useless statement to the point of being
a lie by omission. (a) BC contact tracing has always focused on households and social settings. Data on transmission in BC schools and universities does not exist - remember last fall when public health specifically refused to follow up on schools/uni exposures.
Other jurisdictions have found plenty of school/uni transmission just by looking. (b) "lower" risk is probably true, just like $50 is less than $100. We simply don't know how low the risk is in BC universities really is. "The recommendations of public health and Orders of the Provincial Health Officer are based on careful and ongoing assessment of the factors that increase risk and the interventions that are known to effectively
reduce risk" is
empirically
false. BC's public health assessments and communication often directly contradict public health authorities in
Canada, the
UK, Taiwan, and others. That's a lot of experts lined up on the other side! Lyn: What I'm comforted by is the fact that
protecting oneself from Covid has never been easier. High-quality well-fitted N95 masks are now cheaply available, and maybe you can get your department to buy some in bulk. Not only do they block transmission even for hours of exposure, they are easier
to talk through than cloth masks (i.e., better for teaching). Third vaccine doses offer 75% (UK data) to 88% (Ontario data) protection.
As far as I can tell with my dinky CO2 monitor, SFU's ventilation improvements are real (though I would like to see even more aggressive upgrades -- if you do as well, lobby for them!). Buy your own monitor and
bring it to class. A French expert group recommends a CO2 concentration below 800 for teaching (masked) and below 600 for eating/drinking. If my classroom exceeds a concentration of 1000, I'm prepared to cancel class. (This
hasn't happened yet but I think it would if a classroom was fully occupied.) Build a Corsi box (for ~$100) if you need to be around others in a small room. Suzanne: hope you and your family will be better soon!
According to the experts, PCR tests tend to pick up virus material for weeks after the infection, so you will probably have some certainty soon. And
the most accurate data on metro Vancouver infections is here. Already on the way down, but still about 50x as much virus as we had in early November. Good luck! Lucas From: Suzanne Norman <snorman@sfu.ca> My son contracted Covid from a high school peer this week. Contrary to Dr. Henry’s statements, there is no cohort based learning, no increase in spacing in classrooms, no controlled movement between
classes, and teachers cannot enforce masking (not that they should have to). My son and I are now both home with COVID. As are several of his friends.
Universities are worse. Additionally, finding a rapid test anywhere has proven to be like finding hen’s teeth. Despite the millions of tests the feds gave the provinces, there are none to be found for individuals here
in BC. I have tried. In Ontario, packs of tests were sent home with kids. In Alberta you can pick them up from drugstores (for free). Here you either don’t test or you wait days to test. Our pcr test is set for Saturday in Abbotsford. It took data to get it.
Will our tests be positive then? No idea. I would like to know even for our peace of mind. But I want our data reported. A rapid test with online reporting would be much more efficient and likely a better measure of actual numbers. A friend of mine with five family members sick just gave up looking for a test. No
data from them. Thankfully we are not that sick (yet). But it angers me that data are going missing because of a lack of access to testing. I can only imagine the struggles people are having across our population. SFU and UBC should be in sync with online learning. We are geographically close and in each other’s health authorities and it makes sense for us to also wait til Feb. Suzanne Norman
