What type of disease is plague classified as?

Plague is classified as a bacterial disease because it is caused by the bacterium Yersinia pestis. This pathogen primarily affects rodents and can be transmitted to humans through flea bites or direct contact with contaminated animals. The disease has historically caused significant outbreaks and is known for its severe symptoms, including fever, chills, and swollen lymph nodes (buboes), hence the name "bubonic plague."

Understanding that plague is bacterial underscores the importance of targeting the specific bacteria when addressing its transmission, prevention, and treatment. It also separates plague from other types of diseases, which are caused by different pathogens—viruses, fungi, or parasites—that require unique approaches for treatment and management.
