Mankind has suffered numerous plagues, some of which are particularly serious, which have a great impact on future generations: coronavirus pneumonia-19, SARS, plague, smallpox, influenza, cholera, malaria and so on. Generally speaking, plague is an infectious disease caused by some highly pathogenic substances, such as bacteria and viruses. It is generally caused by poor sanitary conditions after natural disasters.
Epidemic plague
The plague in Athens lasted from more than 2400 years ago to the middle and late19th century.
A disease more than 2400 years ago almost destroyed the whole of Athens. For more than a year, the citizens of Athens have lived in a nightmare. The strong young people around him suddenly had a high fever, and their throats and tongues were congested, giving off an unusually unpleasant smell. Unfortunately, the patient sneezed, his voice was hoarse, and he had chest pain because of a severe cough. A doctor found that fire could prevent epidemics, thus saving Athens.
