Years ago I read a book THE PLAGUE AND THE FIRE about the devastation in 1665-1666 England. After a year of the plague, the fire of London started. While the plague was waning, there were still a large number of plague deaths when the fire began.
The Great Fire of London in 1666 was looked upon as a chance to cleanse London of the plague once and for all, and an opportunity to redesign the city.
