Episode notes
INSIGHT

COVID Is Endemic Not Eradicated

  • COVID-19 is here to stay as an endemic virus causing fewer severe cases due to immunity and vaccines.
  • Current weekly deaths (~150–160) are real COVID-attributable deaths, not fabricated numbers.
ADVICE

Use Hospital Census To Trigger 'Snow Days'

  • Use hospital capacity triggers (like 90–95% bed census) to implement temporary community 'snow days'.
  • Reduce public contact until hospitals can provide good medical care to minimize deaths.
INSIGHT

A Far Deadlier Coronavirus Is Plausible

  • Dangerous coronaviruses exist that combine COVID-like transmissibility with SARS/MERS-level fatality.
  • A future spillover could plausibly kill far more than COVID's ~1.5% fatality.
