Pathology This preprint made a model which predicts positive PCR tests based on seven symptoms: loss or change of sense of smell, loss or change of sense of taste, fever, new persistent cough, chills, appetite loss, and muscle aches. This can possibly replace tests in places where tests either are not available or when someone… Continue reading 2021-09-30 General

Testing/Diagnostics In this study, they put a wristwatch-like thing on the wrists of people who willingly allowed themselves to be infected with either rhinovirus, flu, or placebo. The wristwatch thingie was able to predict illness about a day before symptoms showed up. This could be really useful for diagnosing other respiratory infections (like ahem COVID-19).… Continue reading 2021-09-29 General

Treatments It’s been observed often that obesity raises the risk of COVID-19. This preprint looked into it more closely, and found that the anti-obesity drug orlistat blocks COVID-19 in mice. Mitigation Measures This report from England looked how behaviour correlated with risk of getting COVID-19. People who reported that never wore masks were slightly over… Continue reading 2021-09-28 General

Pathology A paper last week said that the risk of heart inflammation in young men was one in a thousand. As this article reports, they were waaaaaay off in their count of the total number of vaccinations in Ontario; the correct figure turns out to be one in 1 in 25,000. I can’t for the… Continue reading 2021-09-25/26/27 General

Mitigation Measures This US CDC report says that counties with school mask mandates had lower absolute pediatric case rates (16.32 per 100K/day vs. 34.85 per 100K/day) and a lower increase in cases after school started. This (different) US CDC report says that counties without a mask mandate in schools had a 3.5x higher chance of… Continue reading 2021-09-24 General

Vaccines This long and highly technical preprint also says that the MMR vaccine gives some protection against and that the Tdap (Tetanus, diphtheria, and pertussis) vaccine does. The authors did two things: They took T cells from blood which had SARS-CoV-2 antibodies (either from infection or vaccination) and added either MMR or Tdap vaccines, and… Continue reading 2021-09-23 General

Vaccines In this study, the authors made pseudoviruses — things which have SARS-CoV-2 spikes on them but which can’t infect people, and “mutated” the spikes. They were able to find a mutant spike that were almost completely resistant to antibodies from either people who had had COVID-19 and had not been vaccinated or who had… Continue reading 2021-09-22 General

Mitigation Measures The land border into the USA from Canada will remain closed to non-essential non-Americans until at least 21 October. Vaccines This preprint says that the MMR (measles, mumps, and rubella) vaccine has a vaccine effectiveness against symptomatic COVID-19 infection of 48% and 76% effectiveness against severe disease. I think this is huge news,… Continue reading 2021-09-21 General

COVID-19 Origins This preprint says they have found a bat coronavirus which looks really close to SARS-CoV-2. It looks to me like that’s the origin! Does this mean an end to speculation about SARS-CoV-2 coming from a Chinese lab? Oh hell no, because they have too much fun with conspiracy theories and because it’s not… Continue reading 2021-09-17 General
