But with the advent of the agricultural revolution 10,000 years ago, and the arrival of permanent settlements in the Middle East, people began living side-by-side with animals, which made the diseases from cattle spread to humans.

During any infection, the immune system launches an immune response called the innate response. It is a natural response that releases cytokines, an important microscopic protein that acts as an alarm. They generate inflammation. Eventually, it releases a second wave of immune cells. This is called an adaptive respo
