the symptoms of the disease the geographical area affected the species of organisms infected the season in which the disease spreads
I gave my students this multiple choice question: Which is a distinction between an epidemic and a pandemic?

Only one answer is correct among these 4 choices:
- the symptoms of the disease
- the geographical area affected
- the species of organisms infected
- the season in which the disease spreads

Could you tell me which one is correct?

the geographical area affected
