It spread equal through night as it did through the day cholera choose victims the lottery way. For it's little to matter, if you lived upstairs or down, like the air that we breathe, the threat always round. It grabbed hold of the cities, it's grip tight, unforgiving, no wall could deter it, no way to stay living. While some of your neighbors, stayed put, kept inside, when cholera stuck, they would not survive. Normalcy gone, with the rest it had fled, to live was to say, you're just not yet dead.
"Whilst pestilence slays its thousands, fear slays its' tens of thousands." - Saying created during the plague in England during the 17th century.
