Plague is an infectious disease caused by Yersinia pestis and is mainly transmitted to humans through flea bites.

Characteristics of plague include high fever, swollen lymph nodes, rash, and severe respiratory symptoms.

The main routes of transmission include flea bites, contact infection and airborne transmission.

Plague is an ancient disease that has affected the development of human history.

During the Black Death in the 14th century, plague killed a large number of people.

Although the incidence of plague has declined significantly in recent years, it still occurs worldwide.

Plague prevention primarily involves improvements in personal and environmental hygiene, as well as flea and rodent control.

Vaccination can also effectively prevent the occurrence of plague.

When an epidemic breaks out, timely adoption of control measures such as isolation, disinfection, and drug treatment is key.

Outbreaks of plague can lead to reduced movement of people, cessation of business activity, and economic decline.

With the improvement of medical conditions and advances in treatment methods, the socioeconomic impact of plague has been greatly reduced.

Plague still exists in certain epidemic situations in Africa, Asia and the Americas.

Nonetheless, through international cooperation and widespread vaccination, the scale of global plague epidemics has been significantly reduced.

Plague research focuses on vaccine development, epidemiological investigations, and treatment improvements.

Effective antibiotic treatments already exist to control and cure plague.

With the deepening of research, there is more hope for the development of new drugs and vaccines for plague.
