The town of Eyam in central England is often referred to as the 'plague village.' In the summer of 1665, an outbreak of the plague was discovered in the town, and the residents decided to isolate themselves to prevent the spread of the disease. After nearly a year and a half, when the town reopened, over 70% of the population had perished. Interestingly, about 30% of the population survived. Some families lost all but one member: for instance, John Smith lost his wife and four children but remained healthy throughout the ordeal. Smith's experience was not isolated; many survivors appeared to be immune to the infection. Researchers have noted that a significant number of descendants of plague survivors from Eyam possess a mutation of a gene known as delta 32.
