When can the earliest plague record in China be traced back?

The earliest record of plague in China can be traced back to the pre-Qin period. For example, "Zhou Li Tianguan Notes" records: "People's diseases are raised by diseases, and they are always sick." "Lu Chunqiu Ji Chun Ji" records: "Ji Chun is prosperous in Xia Zhishi, and the people are ill." It shows that the knowledge of plague has reached a certain level at that time, and it is believed that plague can occur all year round. One of the reasons is that the seasonal qi is abnormal, which is caused by "untimely qi"

In fact, the earliest writing in China, Oracle bones in Yin Ruins, has recorded the words "worm", "law" and "malaria", especially "furuncle" which means "plague" in the ancient philology of China. This word appears and is used in Shangshu, Shan Hai Jing and Zuo Zhuan, which should be the earliest written document of plague in China.
