Is COVID-19 transmitted by airborne aerosols?
A recurring debate about COVID-19 bubbled up late last week, when a group of scientists announced an as-yet unpublished open letter to the World Health Organization arguing that COVID-19 transmission is airborne and urging it to change its recommendations. What is this debate about, and, if coronavirus is airborne, should we be more scared?
Misinformation and disinformation about facemasks and COVID-19
As evidence accumulates that facemasks work to decrease the risk of spreading COVID-19, new myths have arisen claiming that, not only do facemasks not work, but that they are actively harmful. These myths have no basis in physiology or chemistry, but that hasn't stopped anti-mask activists from using them to claim protection under the Americans With Disabilities Act.
Antivaccine leader Del Bigtree on COVID-19: “Let’s catch this cold!” Why antivaxxers and coronavirus conspiracy theorists are often one in the same.
Last week, antivaccine activist Del Bigtree posted a rant denying the severity of COVID-19, blaming the chronically ill for having made themselves vulnerable to severe disease through their lifestyle choices, and urging the young and healthy to "catch this cold". His rant shows exactly why COVID-19 conspiracy theorists and antivaxxers have such an affinity for each other and have teamed up to...
J.B. Handley’s unthinking person’s guide to the COVID-19 pandemic
J.B. Handley was the founder of the antivaccine group Generation Rescue. Unfortunately, in the era of COVID-19 he's started peddling pseudoscience related to the pandemic. Some things never change.
Antivaxxers launch a preemptive disinformation war against a COVID-19 vaccine that doesn’t yet exist
We don't yet have a vaccine against COVID-19, but that hasn't stopped the antivaccine movement from launching a preemptive disinformation war on social media against it. Unfortunately, as a recent study demonstrates, on Facebook at least, they have been so successful that it is possible that antivaccine messaging will surpass pro-vaccine messaging on FB within a decade.
Medical conspiracy theories and COVID-19
The COVID-19 pandemic has spawned almost innumerable conspiracy theories, and conspiracists like the antivaccine movement have joined forces with COVID-19 conspiracy theorists. To combat the proliferation of pseudoscience rooted in conspiracy theories, it is useful to step back and examine the nature of conspiracy theories, including ones that are not medical, even ones like QAnon. Critical thinking is the key to inoculating...
Plandemic: Judy Mikovits and the mother of all COVID-19 conspiracy theories (some final thoughts)
Last Friday, I deconstructed Plandemic, a misinformation conspiracyfest of a video that went viral last week. It turns out that Judy Mikovits, the disgraced scientist featured in the video has even more conspiracy theories and misinformation up her sleeve.
Plandemic: Judy Mikovits and the mother of all COVID-19 conspiracy theories
Judy Mikovits is a disgraced scientist who published a paper claiming that a retrovirus called XMRV causes chronic fatigue syndrome, results that other investigators were unable to replicate. Since then, she's been a regular on the antivaccine circuit, but now she's been reborn as a "Fire Fauci" COVID-19 conspiracy theorist. Sadly, it worked. Her book is #1 on Amazon.
COVID-19: Out-of-control science and bypassing science-based medicine
During the COVID-19 pandemic, there hasn't just been a pandemic of coronavirus-caused disease. There's also a pandemic of misinformation and bad science. It turns out that doctors today are just as prone as doctors 100 years ago during the 1918-19 influenza pandemic to bypass science-based medicine in their desperation to treat patients.
Do face masks decrease the risk of COVID-19 transmission?
As wearing masks to prevent the spread of COVID-19 becomes a culture war issue, the evidence for whether they prevent transmission of COVID-19 remains contested. A new systematic review and meta-analysis provides the best evidence yet that social distancing and masks are highly effective at decreasing the risk of contracting coronavirus, while eye protection might also help, but it's not a slam...
