PLAGUE

Plague is particularly common in poor cities, but it poses a threat everywhere. Cities without sewer systems (or with poor or dilapidated ones) expose their citizens to filth fever and other foul diseases. In the most impoverished districts of some cities, corpses are left to rot for hours or days before they are collected for burial. Plague is less of a threat in most D&D cities than it might have been historically, due to the ability of clerics and other classes to cure it, but an epidemic that spreads quickly might grow beyond the ability of the churches to contain it. Plagues inevitably cause panic, closures, and violence as people struggle for supplies or attempt to rid themselves of those whom they believe are spreading the pestilence.
