Mitigation Measures This article says that people can now apply for the federal Canada Worker Lockdown Benefit of up to $300/week, retroactive to 19 Dec. Variants This report from Ontario Public Health says that, after adjusting for vaccination status, the risk of severe illness from Omicron is 54% that from Delta. This preprint (from August)… Continue reading 2021-12-30 General

Variants There continue to be studies in test tubes and lab rodents which all show pretty convincingly that Omicron does not infect the lungs as well as previous versions. This preprint says that T cells from vaccination still have 70-80% of their protection against Omicron (which is probably why breakthrough cases are mild). Transmission This… Continue reading 2021-12-29 General

Press Briefing Stuff they said that I’m not sure I’ve mentioned before: Omicron’s incubation period — the time from infection to infectious — is about three days, vs. six for previous variants. By the time you get symptoms and get tested, it’s too late. With two doses of vax, you are much more likely to… Continue reading 2021-12-29 BC

Testing This article says that any self-reported positives on rapid antigen tests which get submitted via the province’s survey (which I posted a few days ago) do not get reported in the province’s daily numbers. (I guess that’s because if they did, malicious actors would artificially inflate the numbers?) There is a user-driven site where… Continue reading 2021-12-27/28 BC

Variants There has been difficulty figuring out how badly Omicron is going to hit the hospital system first because it is a lagging indicator, second because Omicron affects vaccinated and unvaccinated people so differently, and third because of poor-quality data around the holidays. Still, there are hints that, as this tweet from New York says,… Continue reading 2021-12-25/26/27/28 General

NB: I have a tendency to say “we” when I am talking about BC public health. I am not employed by pub health (or actually anyone at the moment). I say “we” as a British Columbian invested in the system. It is OUR health care system. Press Briefing Testing Case counts continue to soar. Yesterday… Continue reading 2021-12-24 BC

This is short because Happy Christmas Eve! Testing This paper from October says that there is 1.7x variation in PCR test results over the course of a day, with 2pm being the time when an infected person will have the highest viral load. This article says that it’s not legal for you to redistribute rapid… Continue reading 2021-12-24 General

Variants I have been frustrated with some of the talk around Omicron’s virulence, and this tweet made me realize what my problem was: we shouldn’t be talking about THE virulence (usually expressed as the Case Hospitalization Rate or CHR) as a single number. There is a different CHR for the general population (the observed virulence)… Continue reading 2021-12-23 General

IMPORTANT! If you tested positive on a rapid test in BC and did not get a PCR test, pub health asks that you please go to https://www.vch.ca/covid-19/you-have-tested-positive, click on the purple “Complete your assessment” button, and fill out the form. (It’s easy, takes five minutes.) I cannot speak for pub health, but I can imagine… Continue reading 2021-12-23 BC

I am going to take the rest of the day off as a mental health break. Brief bits from what I have already seen: UK had 100K cases yesterday, which sounds like an unimaginatively huge number until you realize that’s ~6K cases/day when adjusted for the different population — which is only two doublings from… Continue reading 2021-12-22 BC/General
