https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4420971/ is skeptical of cloth masks. Does anyone have any thoughts on it, or know any other studies investigating this question?

I noticed this too. When wearing a bandana as a mask, humidity is building up while exhaling, causing it to be slightly damp.

6cata2moMea culpa, that's more of a condemnation than I thought.
4ChristianKl2moIt seems the primary argument for clothing masks that's made is that if an infected person wears them it's less likely that they will infect others. That's not the purpose that was tested in "A cluster randomised trial of cloth masks compared with medical masks in healthcare workers" [https://www.researchgate.net/publication/275360639_A_cluster_randomised_trial_of_cloth_masks_compared_with_medical_masks_in_healthcare_workers] that study seemed more about whether or not the masks have protective qualities for the wearer.

April Coronavirus Open Thread

Last month’s Coronavirus Open Thread did a fantastic job at being a place for coronavirus-related information and questions that didn’t merit a top level post, but at almost 400 comments, many of which were great at the time but are now obsolete, it’s getting a little creaky. So for the next month (probably. Who knows what’s going to happen in that month) this is the new spot for comments and questions about coronavirus that don’t fit anywhere else and aren’t worth a top level post.

Wondering what happened in last month’s thread? Here are the timeless and not-yet-eclipsed-by-events highlights:

  • Spiracular on why SARS-Cov-2 is unlikely to be lab-created.
  • Two documents collating estimates of basic epidemiological parameters, in response to this thread
  • Discussion on whether the tuberculosis vaccine provides protection against COVID-19.
  • Suggestive evidence that COVID-19 removes sense of taste and smell.
  • Could copper tape be net harmful?

Wondering why the April thread is going up on 3/31? Because everything’s a little more confusing on 4/1 and I didn’t want the extra hassle.
