COVID-19 Long COVID This paper from Germany (2025-07-12) found that 21% of masters’ athletes (median age in the high 50s) had Long COVID.

Vaccines/Prevention 💊 This paper from Peru (2025-07-11) looked at… Continue reading 2025-07-19 General

Long COVID This paper from USA (2025-06-18) reports that a Delta or pre-Delta infection was protective against further Long COVID, while an Omicron infection was not. People whose first infection was pre-Omicron had about half the chance of getting more than three persistent symptoms after their second infection than after their first. However, people who… Continue reading 2025-07-04 General

🤦‍♀️🇺🇸 If this post feels unusually short, that’s, well, because it is. There has been a really striking lack of news appropriate for this blog this week. The English-language health news has been absolutely overwhelmed with stories of the fusterclucks going on in US health politics. Recommended Reading ⭐️💉 Some people note that kids these… Continue reading 2025-06-27 General

🌊 This article from Singapore (2025-06-14) says that their wave is now peaking, about five or six weeks after their wave started in late April. That feels a bit fast to me — we usually see two months from the start to the peak here. I’m also a bit surprised that COVID-19 growth here has… Continue reading 2025-06-20 General

A number of COVID-19 indicators show the levels going up: wastewater (especially in Fraser), % positivity, # of patients in hospital, and # of hospital admissions. I don’t feel comfortable saying “cases are low” any more. I would like to remind people that: Go get your COVID-19 vaccination! Charts From the BC Viral Respiratory Outcomes… Continue reading 2025-06-06 BC

COVID-19 Variants 🦠🧬 NB.1.8.1 is still causing a lot of cases in Asia and Australia. It has acquired two nicknames: “NimBus” (from the two letters in its designation) and “Razor Blade Throat” because it apparently feels like you’ve been swallowing razor blades. Long COVID 🩸‼️ This preprint using UK participants (2025-05-26) has a potential explanation… Continue reading 2025-06-01 General

COVID-19 Variants Other people are starting to notice all the cases in Asia. This article from USA (2025-05-23) says that CDC has discovered a bunch of cases of NB.1.8.1 — the variant which is causing havoc in Asia — in wastewater arriving in planes from abroad. I know, I know, the US is not Canada,… Continue reading 2025-05-24 General

COVID-19 Long COVID 👃 This paper from Belgium (2025-05-03) reports that people with COVID-related olfactory disorders had a 17% higher risk of depression and a 22% higher risk of anxiety than asymptomatic people.

COVID-19 Transmission In the 2024-04-04 BC post, I said that I had figured out why the COVID-19 levels were so low right now: because influenza inhibits COVID-19! Aha! Well, that’s bullshit. I don’t have good data going back a long time for flu in BC, but this chart of flu, COVID-19, and RSV levels from… Continue reading 2025-04-27 General

Omni-Testing 😮🩸‼️🎉 This paper (2025-02-21) reports on a method of sequencing the genomes of T-cells and B-cells from a patient’s blood sample which allows them to diagnose with great accuracy what pathogens the patient has been exposed to. Apparently B cells and T cells don’t have the genome of the rest of the body, but… Continue reading 2025-04-18 General
