       | Yes, that is the kind of epidemic for which social isolation is
       | an appropriate response.

           | 
           | Mitigation efforts are certainly worthwhile, but there are
           | significant diminishing returns.
           | 
           | I would guess that 80/20 rule applies to mitigation efforts
           | just as much as anything else. The vast majority of
           | protection is provided by a fairly minimal set of
           | precautions.
           | 
           | I think we see this borne out in the data. The places with
           | the strictest lockdowns are doing better than the places with
           | fewer restrictions. However, the numbers aren't so night and
           | day different as to suggest that those additional lockdowns
           | have been worth the price.
           | 
           | One thing I've wondered is how many "odd" social customs in
           | various cultures (no singing / dancing, face coverings, etc.)
           | could actually be explained by past epidemics. We've
           | certainly adopted many of those restrictions in short order.

       | It should be noted that social distancing is an ancient practice
       | even before 1500. For example before 1400 years back, the Persian
       | Islamic scholar Muhammad al-Bukhari recorded the following 7th-
       | century hadith : "If you hear of an outbreak of plague in a land,
       | do not enter it; but if the plague breaks out in a place while
       | you are in it, do not leave that place."

         | Quarantine is nothing new. The medieval trading republic of
         | Ragusa had an island in their harbor specifically for
         | quarantining new arrivals. It's a shame that people even
         | contest the logic today when wholly uneducated people were fine
         | with it hundreds of years ago.

             | Indeed lockdown and quarantine are different things. The
             | countries that have had proper quarantine eg Vietnam, NZ,
             | Thailand have mostly done rather better with covid than
             | those who have not eg. the UK and USA.

           | Yep - the word quarantine itself comes from the Italian
           | "quaranta giorni" (forty days). This was the amount of time
           | that ships arriving in Venice from infected ports were
           | required to sit at anchor before landing, so as not to infect
           | the Venetians.
