Which term describes a worldwide epidemic, such as the 1919 influenza pandemic?

• A. Epidemic
• B. Pandemic
• C. Endemic
• D. Carrier Status

Answer: (B)

A global spread of disease is described as a pandemic. A pandemic means the illness has crossed borders and affected people across multiple countries and continents, often impacting a large portion of the world. The 1919 influenza outbreak is the classic example because it spread far beyond any one region, infecting people worldwide.

By contrast, an epidemic refers to a surge in cases in a specific area or community, not necessarily worldwide. Endemic describes a disease that is regularly found in a particular region with a steady baseline level of cases. Carrier status refers to an individual who harbors the pathogen and can spread it, but it doesn’t describe how widespread the disease is geographically.
