The temperature – COVID connection …

A team of researchers at Goldman Sachs turned on their regression machines and found a compelling relationship between outside temperature and CODID case confirmations.

Goldman’s bottom line: As temperatures get colder, the incidence of COVID cases increases — pretty dramatically, regardless of local COVID mitigation policies.    Source

Goldman points out that’s not surprising since:

Most other coronaviruses (i.e. the common cold), along with various influenza strains, are heavily influenced by temperature and seasonal effects (hence “flu season.

Why is that?

  • Researchers have found that the human immune system weakens in cold temperature, making people more vulnerable to viruses
  • Cold weather forces more people to be indoors more often, making them susceptible to infection if a  “carrier” breaches their poorly ventilated “bubble”.

My add: Note that 72 to 80 degrees is the sweet spot.  That’s the temp at which most people turn off their homes HVAC systems, reducing the circulation of any airborne contaminants.  Hmmm.
