Weather This article says that the amount of lightning decreased during the pandemic because of less fossil fuel burning and hence fewer aerosols. Vaccines This article says that in extremely rare circumstances, people report Long COVID symptoms after vaccination. Variants This preprint says that the risk of hospitalization from Omicron is 25% that of Delta,… Continue reading 2022-01-22/23/24 General

Vaccines This preprint says that there were zero children in France who had been fully vaccinated and went on to develop MIS-C. Pathology This preprint says that kids recover pretty well from MIS-C.

Treatments HOORAY!!! As this article reports, Health Canada approved Paxlovid (an oral treatment for COVID-19 which cuts hospitalizations by almost 90%) today! Not only that, there are already about 30K doses in-country! Supplies are going to be limited for a while. Until then, Health Canada recommends prioritizing severely immune-compromised patients, people over 80 who don’t… Continue reading 2022-01-15/16/17 General

Transmission Yesterday in the BC blog post, I gave a bunch of evidence for Omicron being a very “pointy” wave, fast up and fast down. Wastewater evidence from the eastern USA is also pointing to fast-up/fast-down. From this tweet, the wastewater SARS-CoV-2 surveillance in Boston: And from this tweet, the surveillance in New Haven, CT:… Continue reading 2022-01-12 General

Vaccines Studies of the effectiveness of boosters against Omicron in humans (as opposed to test tubes) are starting to come out, and they are not as encouraging as one would like. This preprint from the UK says in people who got AZ, a Pfizer booster is 89.1% effective against symptomatic infection and for those who… Continue reading 2022-01-05 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

Variants More qualified good news: this preprint out of South Africa says that Omicron is only 70% as likely to send someone to the hospital as Delta. All the same caveats I’ve made previously apply, though. This Twitter thread does an estimate of the Case Hospitalization Rate (CHR) in New South Wales, Australia. This is… Continue reading 2021-12-21 General

Mitigation Measures This article says that the federal government is advising against international travel. (If you go to the travel advisory page, for every country, it says you shouldn’t go there.) This article says that the Finance Minister Chrystia Freeland committed a whole bunch of money to fight COVID-19 . Variants There were a ton… Continue reading 2021-12-15 General

Variants According to this Twitter thread, which reported on a press conference in South Africa, Omicron now accounts for 90% of the cases in South Africa. (Note: it might not be displacing Delta, there might still be just as many Delta cases as before — I don’t now — but a huge number of Omicron… Continue reading 2021-12-14 General
