Was there really a plague epidemic in ancient times?

In ancient times, there were many plagues. In the past, infectious diseases were called epidemics, and those with short time and no serious diseases were called seasonal epidemics: epidemics, and both people were sick. It takes a long time to happen, and it is quite serious. After infection, the body temperature will increase obviously and become a "warm" epidemic. Infectious diseases were frequent in ancient times, and there were many records about infectious diseases in ancient times. Various historical books * * * recorded 772 plagues of different degrees, and the frequency of plagues can be seen. This does not include plagues that have not been recorded due to lack of information or other reasons.

There are many reasons for the plague, and the underdevelopment of ancient science and technology will lead to considerable disasters. People gradually worked out a set of rules of plague occurrence. These laws include the period of frequent plague and the process of slow decline of plague. Taking our 24 solar terms as the time point, the plague is most likely to start, and the plague subsides with the solar terms as the reference. That is to say, the old saying goes: the plague began with heavy snow, originated from the winter solstice, was born in a slight cold, flourished in the beginning of spring, was weaker than rain, and was weaker than fright. This folk saying about the plague is the whole development process of the plague.

In AD 1 and 196, according to Zhang Zhongjing's book Treatise on Exogenous Fever and Miscellaneous Diseases, exogenous febrile diseases and severe infectious diseases were collectively called "typhoid fever" at that time, and two-thirds of people who got typhoid fever died, showing the seriousness of the epidemic at that time.

2. In 2 17 AD, boils prevailed. According to Cao Zhi's "Talking about Epidemic Qi", boils caused many deaths and some even genocide, which described the tragic situation at that time in detail. The anger was caused by the wrong time of summer and winter, but people at that time believed in ghosts and gods, which shows the ignorance of people at that time.
