Last interesting factoid: contrary to the belief that you contracted plague and died shortly after, the reality seemed to be that the disease took 37 days to manifest itself fully. For the first 12 days, you weren't contagious. Then for the next 20 days, you were highly contagious. Then, the last 5-7 days, you manifested the virulent symptoms and died.
Of course, this is all stuff that is being slowly studied and science isn't entirely sure on what caused it and why it spread so fast, when successive plague outbreaks spread so slowly.
Now, make that into a highly panic-inducing scenario and send it to NYC for Ethel and Italios to manage.
