On June 30, 1665, the number of deaths in London from the Great Plague during June was recorded as 6,137 people. It only got worse from there. An excerpt from the article:
"In two successive years of the 17th century London suffered two terrible disasters. In the spring and summer of 1665 an outbreak of Bubonic Plague spread from parish to parish until thousands had died and the huge pits dug to receive the bodies were full. In 1666 the Great Fire of London destroyed much of the centre of London, but also helped to kill off some of the black rats and fleas that carried the plague bacillus.
Bubonic Plague was known as the Black Death and had been known in England for centuries. It was a ghastly disease. The victim’s skin turned black in patches and inflamed glands or ‘buboes’ in the groin, combined with compulsive vomiting, swollen tongue and splitting headaches made it a horrible, agonizing killer.
The plague started in the East, possibly China, and quickly spread through Europe. Whole communities were wiped out and corpses littered the streets as there was no one left to bury them.
It began in London in the poor, overcrowded parish of St. Giles-in-the-Field. It started slowly at first but by May of 1665, 43 had died. In June 6137 people died, in July 17036 people and at its peak in August, 31159 people died. In all, 15% of the population perished during that terrible summer.
Incubation took a mere four to six days and when the plague appeared in a household, the house was sealed, thus condemning the whole family to death! These houses were distinguished by a painted red cross on the door and the words, ‘Lord have mercy on us’. At night the corpses were brought out in answer to the cry,’ Bring out your dead’, put in a cart and taken away to the plague pits. One called the Great Pit was at Aldgate in London and another at Finsbury Fields."
