What term describes several cases of disease in a certain area?

• A. Epidemic
• B. Disease Cluster
• C. Endemic
• D. Pandemic

Answer: (B)

Grouping of cases in a localized area is described as a disease cluster. This term is used when several cases occur in a specific place or over a short period, which may suggest a common exposure or source and prompts public health investigation. It doesn’t necessarily mean incidence is higher than expected everywhere, but it highlights a concentration of cases in a particular area.

An epidemic, by contrast, refers to a larger-than-expected increase in cases within a population or region, while endemic means a disease is regularly present at a relatively steady level in a population. A pandemic describes an epidemic that has spread across multiple countries or continents.
