Which term describes a large number of cases of an illness?

• A. Pathogenicity
• B. Intervention
• C. Epidemic
• D. Zoonoses

Answer: (C)

This question tests your understanding of how epidemiology describes how often illness occurs in a population. An epidemic is a spike in the number of new cases of an illness in a specific population within a defined time, exceeding what is normally expected. It focuses on the rate and scale of cases in a particular area, not on the inherent ability of the pathogen to cause disease or on efforts to control it. Pathogenicity refers to how capable a pathogen is of causing disease, which is about the organism’s properties rather than the count of cases. Intervention means actions taken to prevent or respond to disease, not the frequency of illness. Zoonoses are diseases that can be transmitted from animals to humans, not a description of how many people are affected. If anything helps, an epidemic in a limited region contrasts with a pandemic, which spreads across wider areas.
