(Joint with HsingChi von Bergmann, health science education researcher, professor at UBC Faculty of Dentistry, previously associate professor and science teacher educator at UofC) Schools across BC are set to resume this coming Monday, January 4th. Meanwhile British Columbia universities have delayed the start of the semester by a week to gauge the fallout from Christmas and New Year celebrations, and other Canadian provinces with similar case rates are delaying their school starts, Ontario by at least a week, Manitoba will keep grades 7 to 12 in remote learning for two weeks while younger children can choose between remote and in-class learning, and Regina is keeping students in remote learning for the first week after the break.
What do we know about COVID-19 testing in BC? That’s a surprisingly tricky question, so I decided to do a quick post on this. Why do we test? The main use of testing is diagnostic and to break transmission chains. If we suspect a person has COVID-19 that person will go into self-isolation and seek a test. If the test confirms the suspicion, we contact trace the COVID-positive person and ask close contacts to self-isolate to break transmission chains.
We are growing increasingly concerned with the COVID-19 situation in BC. In particular the way there seems to be no strategy or goal to stop rising case numbers, and the relativism that excuses this by pointing to other provinces and countries that are doing worse. At upward of 150 cases a day we are looking at an average of one death a day and unknown numbers, likely in the mid to high two digits, with long lasting morbidity due to a COVID-19 infection.
BC schools are about to restart, and there is a high level of anxiety among parents and teachers. In this post we will outline some common concerns, and run modelling adapted from the University of Washington network-based model to test the relative effectiveness of various test, trace, and isolate (TTI) scenarios. Cases in schools There will be cases at schools. Quebec already has over 180 schools with reported cases, Ontario had over 7 on their first day of school.
I was browsing the Canadian Perspectives Survey Series 3 on Resuming Economic and Social Activities During COVID-19 and thought that some of the results were interesting. I don’t have time to do a detailed post on this, but thought that others might enjoy a quick series of graphs highlighting some of the result. The survey is only released as microdata, and I have not seen much uptake or reporting other than the high-level results put out by StatCan in The Daily.
