Epidemics caused by viruses began when human behaviour changed during the Neolithic period, around 12,000 years ago, when humans developed more densely populated agricultural communities. This allowed viruses to spread rapidly and subsequently to become endemic.

The origin of viruses is poorly understood, but most virologists (people who study viruses) agree that each virus got started by copying a few useful genes from their host cells. Viruses are ignorant of any patent or copyright laws, they just make a copy of what they find useful in the host’s genome and move on.
