Some of the earliest written descriptions of smallpox date from 4th century CE China and, as trade along the Silk Roads increased in the 6th century CE, the disease spread rapidly to Japan and the Korean Peninsula. Notably, smallpox broke out between 735 – 737 CE in Japan, where it is believed to have killed up to one-third of the population.
