No, the plague and other ancient diseases do not surface every year in every country. [1, 2]
## Key Facts About Ancient Diseases Today
* Endemic, Not Universal: The plague (caused by the bacterium Yersinia pestis) is endemic (naturally present) in wildlife and rodent populations in specific parts of the world—including regions in Africa, Asia, and the Americas—rather than appearing everywhere. [1, 3, 4]
* Global Numbers: According to the [World Health Organization (WHO)](https://www.who.int/news-room/fact-sheets/detail/plague), human cases happen every year, with the majority occurring in Africa (such as Madagascar and the Democratic Republic of the Congo). [1, 5]
* United States Cases: In the U.S., an average of about 7 human cases occur each year, mostly restricted to rural areas in western states like New Mexico, Arizona, Colorado, and California. [2, 6]
* Treatment Available: Unlike in the Middle Ages, modern bacterial plagues and many ancient infectious diseases are quickly and effectively treated with common antibiotics if diagnosed early. [3, 7]
* No 100-Year Pattern: Viral or bacterial outbreaks do not follow a strict chronological schedule or 100-year cycle. Localized scares (such as recent monitoring in Russia) or rare wildlife transmissions do not mean widespread global resurgences. [2, 4, 8, 9]
