the Great Fire of London
The disappearance of plague from London has been attributed to the Great Fire of London in September 1666, but it also subsided in other cities without such cause. The decline has also been ascribed to quarantine, but effective quarantine was actually not established until 1720.

What cured the plague?
The bubonic plague can be treated and cured with antibiotics.
Was the Black Death caused by rats?
Scientists now believe the plague spread too fast for rats to be the culprits. Rats have long been blamed for spreading the Black Death around Europe in the 14th century.
How did rats spread the plague?
Black rats were the most common at this time, and carried the bacteria called Yersinia pestis, which caused the plague. The rats then spread it to fleas that lived on their bodies. The fleas would drink the blood of infected rats, swallowing harmful bacteria. They then passed the infection onto humans by biting them.
How did they catch the plague?
How do people become infected with plague? People most commonly acquire plague when they are bitten by a flea that is infected with the plague bacteria. People can also become infected from direct contact with infected tissues or fluids while handling an animal that is sick with or that has died from plague.

As such, the plague is a zoonosis, an illness that passes from animals to humans. Infection spread easily because the rats were drawn to human activity, especially the food supplies kept in barns, mills, and homes.
What animal spread the Black plague?
Plague bacteria are most often transmitted by the bite of an infected flea. During plague epizootics, many rodents die, causing hungry fleas to seek other sources of blood.
Why did the Black Death disappear in winter?
