Concept:A pandemic is an outbreak of disease that spreads over a very large area, often across many countries or worldwide.
Explanation:An outbreak that is confined to a town is a local outbreak, not a pandemic.
A pandemic is not limited in spread.
It is much wider than an epidemic.
It affects many people over large regions, continents, or the whole world.
The key meaning of the word pandemic is “widespread”.
If a disease has limited spread or will not spread, it cannot be called a pandemic.
Therefore, the option that says the outbreak “is wide spread” correctly defines a pandemic.
All other options suggest that the disease is restricted or not spreading.
Answer:B. is wide spread
