What defines a pandemic?

What defines a pandemic?

• A. Outbreak occurs in multiple continents or worldwide
• B. Outbreak confined to a single country
• C. A seasonal illness affecting a region
• D. An outbreak limited to a city

Answer: (A)

A pandemic is defined by its global reach. It means the disease has spread beyond borders to multiple continents or worldwide, affecting a large number of people. This is what distinguishes it from an epidemic, which is limited to a specific region or country, and from seasonal illnesses or outbreaks confined to a city, which are much more localized. So the key idea is widespread, international spread rather than local or seasonal patterns.
