I get the narrow comedic point of the cartoon — but actually there were many more plagues and millions more deaths among human populations after the infamous Black Death in Europe. Changes for the better in hygiene and medicine developed slowly over hundreds of years, until the scientific bases for their widespread adoption were recognized beginning about the 1800s. Among the persons who helped in this regard were Jenner, Lister, and Pasteur.
The great plague in Europe might have helped to end Feudalism, but in disrupting the feudal system, it eventually led to increases in urban populations, and that led to increased opportunities for diseases to concentrate to kill or debilitate even more. (Among many books on this subject is the classic, “Rats, Lice, and History.”)
The so-called Black Death led eventually to our modern system of commerce, since those who survived in Europe and other areas affected gained whatever wealth and possessions left from the dead. (See “The Day the Universe Changed,” the book and Public Television documentary.)
That’s a simplistic explanation of how things developed, I know. Isn’t it weird how so many people died and suffered to get to our present stage of medical knowledge and methods — and people today still casually spread diseases and refuse to take vaccines and other treatments?
