Many more COVID19 infections may be asymptomatic (but briefly contagious) than we had thought

 

Middletown, MD, 2021

Aria Bendix reports for Business Insider that extrapolations from NYC data last spring suggest that only 13-18% of people infected by coronavirus (detectable in nose, throat or saliva) develop significant symptoms. 

There is some disagreement as to whether asymptomatic people often spread infection and become superspreaders, even though they may have enough natural resistance themselves not to become ill.  This may have to do with genetics, youth, or issues like metabolism.  Younger adults with low body mass index seem to almost never have significant systemic symptoms.  That might change with more contagious variants, or perhaps even with those there will be no systemic disease with people who have fewer ACE2 receptors.  Genetics may be far more important than we realize, and that will be a very discomforting conclusion.  But it may also suggest further treatments. 

But there are other studies suggesting a small portion of symptomatic people are responsible for most of the superspreading, or spread may happen just before major symptoms appear.

But the idea that a “healthy” person is responsible for the well-being of the unhealthy (like obese) sounds rather Marxist.  But then consider the consequences of the opposite.  Fascism?
