Epidemiology stuck in the past

I’m so old, I remember pre-pandemic when all of the published research said cloth facial coverings were mostly ineffective, certified surgical masks were somewhat effective, and N95s were generally effective.

Then in the first week of April 2020, magically, cloth facial coverings were a panacea and we should all wear cloth facial coverings.

I’m so old, I remember the beginning of this year when several countries ordered people to no longer wear cloth facial coverings and to use N95s/FP2s instead. The U.S. White House and the NBA adopted this standard for their facilities, as have many airlines.

So here we are in October 2021 and here is the official advice I was given after being tested for Covid-19 (I have had symptoms since Monday, a week ago).

  • Separate yourself from other people
  • Stay in a separate room and away from other people and pets in your home
  • If possible, use a separate bathroom
  • If you need to be around other people or animals, wear a cloth face covering

They never learn, do they?
