What is an outbreak?

ANSWER

An outbreak is an unexpected, usually sudden, increase in the number of people with a disease in a specific area. A disease outbreak is usually caused by an infection, but the cause may be unknown or due to an exposure to a toxin. Epidemic has the same definition as an outbreak, but generally refers to a larger geographical area.
