A recent common cold may nearly halve risk of COVID-19, study suggests

So Covid-Competent folks - this is going to land different in different quarters.

  • The previously evidence-supported paradigm/metaphor "the immune system is a candle not a muscle" might need to be abandoned for a third, more nuanced position[+]
  • Of course there's the need to check the paper itself, and if it's solid, to replicate / validate, but beyond that.
  • Folks with immune dysregulation can't all just catch rhinoviruses all the time to keep the system active.

[+] probably approximately: "microbes vary:

  • some are overwhelmingly beneficial, eg. in our gut;
  • some have mixed costs and benefits like rhinovirus or conditions when they become pathological like candida, and
  • some basically only have costs like influenza(?), SARS1 and SARS2, measles"
