A plague, often referred to as a curse, is a widespread disease that affects a large number of individuals within a community or population. Historically, plagues have caused significant mortality and social disruption, with notable examples including the Black Death in the 14th century. These outbreaks can be caused by various pathogens, including bacteria and viruses, and are often transmitted through vectors like insects or contaminated surfaces. In addition to physical illness, the term "curse" can imply a supernatural or mystical affliction believed to bring misfortune or suffering. In folklore and mythology, curses are often associated with deities or spirits, and they can manifest in various forms, affecting individuals or entire communities.
