It’s happened here before. Back about a year ago we had an outbreak of Hep A here in San Diego. It did some spreading to other parts of the country, but when counter measures were put into place it pretty much faded away.
The difference between now and then is, Hep A is pretty much known to us so while there was some panic most folks pretty much got on with their lives after taking the steps they needed to handle the epidemic. You know the routine; clean up after yourself, don’t shit anywhere you like, get the homeless off the street, that sort of thing. Of course the homeless are still with us, so Hep A really didn’t have that great an impact on us.
The current affair should fade away to, for as Bob Heinlein once noted, “The most ordinary thing in the world is a ninety day wonder on the ninety first day.”
