Fever 1793 is based on an actual epidemic of yellow fever in Philadelphia that wiped out 5,000 people--or 10 percent of the city's population--in three months. At the close of the 18th century, Philadelphia was the bustling capital of the United States, with Washington and Jefferson in residence. During the hot mosquito-infested summer of 1793, the dreaded yellow fever spread like wildfire, killing people overnight. Like specters from the Middle Ages, gravediggers drew carts through the streets crying "Bring out your dead!" The rich fled to the country, abandoning the city to looters, forsaken corpses, and frightened survivors.
