Days of the Virus: Random Marks

This is a place where I will put some more or less stream-of-consciousness thoughts or notes as they arise.

• First day of (effective) quarantine:  March 14, 2020, starting about 4pm.  
• The last day of quarantine was April 30, 2021, ending about 4:30pm.  
• Etymology of the word "quarantine":  The term comes from the Italian "quarantena" or 40 days, which was the length of time passengers on ships arriving in the Venetian harbor had to wait to disembark during the Black Plague.  
• The R0 of SARS-CoV-2 (the virus that causes COVID-19, a.k.a., the novel coronavirus) has been estimated to be between 1.4 and 3.9, with best estimates around 2.2.  That means that, on average, a person who is inoculated with the virus will pass it on to at least two other people.
