  • Lyman Stone is excited about COVID-19 research that picked random villages in Bangladesh to promote masking and then found that fewer old (55+) people got symptomatic SARS-CoV-2 infections in the villages where masking was promoted, particularly with surgical masks. Even better: Jason Abaluck was on the research team and wrote a thread about the research.

  • There are some relatively rare side effects found in some of the COVID-19 vaccines. We all heard about the rare blood clots from the AZ and J&J vaccines. Did you know that the disease itself can cause blood clots?
• 2021-07-19
  • An article in Slate about COVID-19 digs into the risk to vaccinated people, highlighting the difference between “mild” case as defined by doctors and by laypeople. Essentially, a mild case according to doctors is one that doesn’t require a trip to the hospital or low blood oxygen levels, but it can still feel really terrible for a few days.
• 2021-07-19
  • Eric Feigl-Ding tweeted a bunch of articles with increased outdoor and fleeting contact spread of COVID-19. It’s scary how much more transmissible delta is, but the vaccines are still holding up.

  • Virginia Department of Health has a page detailing the vaccination status of their COVID-19 cases. Over the past month, 97.7% of their cases have been among the unvaccinated, 93.22% of the hospitalizations, and 83.33% of the deaths. Part of the reason the deaths percentage is so low is that there have only been 6 in total during that time frame.
• 2021-07-12
  • Katherine J. Wu writes in the Atlantic about how the term breakthrough infection is leading to a bit of confusion around how well the COVID-19 vaccines work. She suggestions that specifying “symptomatic” and “asymptomatic” is helpful in clarifying that many vaccinated people may become infected with SARS-CoV-2 but never contract the symptomatic illness.
• 2021-07-12
  • COVID-19 is not gone and the delta variant is striking people who are vaccinated, albeit with little in the way of hospitalization or death. Trisha Greenhalgh has written a massive Twitter thread about the problems with finding evidence for mask efficacy and how to wear masks to protect yourself. Double masking (cloth mask over surgical mask) and knotting the ear loops of a surgical mask help.

  • With the Delta COVID-19 variant gaining steam and having significantly different properties from the other variants, it’s useful to see that the CDC has a variant tracker. Delta is B.1.617.2 and Alpha is B.1.1.7.
• 2021-06-15
  • UCSF Dept. of Medicine Chair Bob Wachter has a thread about the Delta variant of COVID-19 and how it seems to have as much an increase in infectiousness over Alpha as Alpha did over the original. He stresses the importance of getting vaxxed now.
• 2021-06-13
  • Granted, this article about how nearly all hospitalized COVID-19 patients are unvaccinated contains no stats, the anecdotes they give are from hospital administrators who saw what things looked like at the worst and are now seeing the improvement.

  • Dylan Morris has an essay in Zeynep Tufecki’s Insight newsletter about COVID-19 and how Novelty Means Severity is the key to the pandemic, because SARS-CoV-2 is a novel virus (one our immune systems haven’t seen before):
• 2021-05-14
  • Zeynep Tufecki wrote just the other day about how the CDC was being timid with their approach to COVID-19. Now, with the CDC announcing that fully vaccinated people don’t need to wear masks or social distance anywhere, Tufecki is arguing for masks a bit longer, and I think she’s right. She points to the sociological aspects of it, and she is a sociologist.
• 2021-05-13
  • The CDC has updated its guidance around COVID-19, saying that fully vaccinated people can essentially return to normal life, with the exception of very specific settings (health care offices, etc.) and subject to laws and rules set by businesses.

  • Jose-Luis Jimenez is one of the authors of The Lancet article about COVID-19 transmission via aerosols. He wrote up an excellent Twitter thread summary of the article. I saw this in his new thread about the history of aerosols vs. droplets. Zeynep Tufecki has a huge article in the NY Times about the history of this particular medical blind spot. It’s an OpEd, but it’s been deeply fact checked.
• 2021-05-01
  • Apparently, some folks are claiming (falsely, as we’ll see) that the COVID-19 fatality rate among vaccinated people is higher among the vaccinated. This isn’t true for multiple reasons: we don’t have a good count of breakthrough cases because they’re more often asymptomatic, and a higher proportion of those who are vaccinated are elderly, which also means they’re at greater risk of serious illness from the disease in general.

  • In early February, Trump knew the dangers of COVID-19 and in March, he said he always wanted to downplay them. As much as his press secretary wants to call this false, there are tapes because Trump voluntarily sat for 18 interviews with Bob Woodward.

• 2020-08-01
  • An article in The Atlantic complains about hygiene theater and the fact that it pulls attention and effort away from the meaningful actions against COVID-19. Something important in the article, though, is a note on research showing how rare fomite (surface) transmission of the virus is.
• 2020-07-25
  • CNN reports that 2 students tested positive for COVID-19 a day after taking the ACT. The ACT and SAT have been on my mind because I have a child at the right age for those tests (who was, in fact, scheduled to take the test in April). I don’t see how we can safely have kids in a room together for 3-4 hours straight, and I’m guessing that many, if not all, of those kids in that Oklahoma classroom were not wearing masks. If they can’t safely administer a test like this, how can they safely have kids in classrooms this fall?
• 2020-07-03
  • The Washington Post spoke to Fauci and others about how they’re staying safe from COVID-19. There’s a lot of similarity in their approaches and little differences around the edges that are interesting.
• 2020-07-03
  • Dr. Van Dyken (a surgeon, not a researcher) posted a video on YouTube about Mask wearing and Hypercapnia. In other words: Does wearing a mask increase your personal CO2 levels dangerously? Short answer: No, because CO2 is tiny compared to COVID-19. Jeremy Howard does a demonstration of this as well.
• 2020-06-26
  • One of my coworkers linked to schools.forhealth.org which offers a report called “Risk Reduction Strategies for Schools”. This report provides some very clear and concise writing about COVID-19 and the challenges and risks of reopening facilities like schools.

  • Covid Act Now is a COVID-19 tracking site that I hadn’t seen before. It provides a good visualization of how each state is doing at controlling the outbreak. It’s good to see Michigan in the green, and I hope it stays that way. Michigan was apparently the only state with a 50% drop in new cases last week.

• 2020-06-11
  • Meanwhile, VP Pence (theoretical head of the COVID-19 task force) apparently didn’t get the memo on masks because he posted a picture of their campaign staff crammed into an office and maskless. Wonder why he deleted that tweet?
• 2020-06-11
  • Though it’s not directly mentioned in the article, it appears that these two hairstylists were wearing masks when they saw 140 customers while showing symptoms of COVID-19. There were records of everyone they had seen, and no one developed the illness! This seems like a big win for masks.
• 2020-06-08
  • Michigan’s COVID-19 numbers have come way down. We do need to worry about demonstrations causing a new wave.
• 2020-06-08
  • Andy Slavitt wrote a Twitter thread about asymptomatic spread of COVID-19, in response to a WHO announcement that asymptomatic people “rarely spread it”. Slavitt says, “I believe this was an irresponsible statement even though it was based on legitimate observations,” and brings the evidence to back up the statement. Update on Tuesday: WHO says 40% of transmissions may be through asymptomatic people.
• 2020-06-06
  • Masks reduce airborne transmission of SARS-CoV-2 reinforces that mask wearing reduces the transmission of COVID-19. The WHO has also revised its guidance regarding mask wearing. Larry Brilliant says “If 80% of the people wore a mask 80% of the time, COVID would go away”.
• 2020-06-02
  • Two epidemiologists have written a NY Times op-ed about COVID-19: Just Stop the Superspreading. “In our study, 20 percent of Covid-19 cases accounted for 80 percent of transmissions.” 70% didn’t spread to anyone. Another similar article in Science.
• 2020-05-31
  • Interesting CNN article about the COVID-19 response from Vietnam, which kept confirmed cases at 328 with no deaths. The did it by acting early and swiftly with extensive contact tracing, isolation, and a modest amount of testing (lots of temperature checking, though). Oh yeah, and a catchy handwashing song.
• 2020-05-28
  • Alistair Haimes’s Twitter thread caught my attention and led me to read the We’re all in the big numbers now. This article is arguing, reasonably so, that COVID-19 lockdown has been very damaging. Given that there are countries and territories that controlled the outbreak without such damaging measures, I think it is likely that we could have responded differently had we been better prepared, and this article concluded with some decent suggestions along those lines.
• 2020-05-28
  • One thing that disappointed me with much of the data is that it’s focused on infection fatality rate (IFR). Fatalities are only part of the story with COVID-19. This disease results in more hospitalizations, according to current CDC data, “Hospitalization rates for COVID-19 in adults (18-64 years) are higher than hospitalization rates for influenza at comparable time points* during the past 5 influenza seasons.” Comparisons with influenza fall down somewhat when considered against the fact that COVID-19 is more likely more deadly but also likely to be more serious in general. However, it sounds like there’s a paper coming out supporting the idea that masks will lead to less severe cases and less deaths. If we’re reducing deaths _and_ severity, that sounds like a huge step.
• 2020-05-28
  • The first interesting COVID-19 claim is that 40-60% of uninfected people could have partial immunity to SARS-CoV-2 due to previous infections with other “common cold” coronaviruses.
• 2020-05-28
  • I listened to an episode of the What Next podcast for the first time, and they featured Emily Oster who runs a site called COVID-Explained, which has a few clear articles that attempt to boil down the latest data about COVID-19.
• 2020-05-28
  • I am more interested in what comes next for COVID-19. I responded with a question: “Are we actually at the tail-end of the epidemic” as Alistair claims? This seems like an important question to ask, because it determines how we respond (as a society and individually) this summer and onward. There were several interesting responses with links to other data.
• 2020-05-28
  • Reason reports that nursing homes account for 42% of fatalities from COVID-19. There has been earlier reporting about high numbers of cases in prisons and meat packing plants. This backs up earlier research that showed sharing indoor space is a major infection risk. Conversely, there appears to be far less risk outdoors. And the jury is still out on a second wave.

  • COVID-19 deaths are actual counts. Jeremy Samuel Faust, an ER doctor and instructor at Harvard, asked other doctors if they could remember anyone dying from influenza. Most couldn’t, some remembered a few, which goes to show just how different COVID-19 is from flu, despite the fact that CDC estimated a bad flu year at 69,000 deaths. Actual counted flu deaths are 3,400 to 15,700 over the past few years.
• 2020-04-24
  • Vi Hart and others have put together a Roadmap to Pandemic Resilience (see also Vi Hart’s How We Reopen video). This plan outlines how we can safely reopen in light of COVID-19. It’s not easy, but it’s important that we do it right, and not in the slapdash manner that some states are pursuing.

  • There are definitely a lot of privacy concerns around contact tracing, and I know a lot of people are concerned that once you let government people start having access to this information, they will never let it go. I understand that concern, but COVID-19 is a huge issue, and I do believe that Apple genuinely cares about privacy. Here is Apple’s documentation about the privacy-preserving contact tracing.
