epidemic: lots of patients

pandemic: lots of patients in lots of countries

Epidemic is centered around an epicentre. 

Pandemic is across, in the present case, the world.

Epidemic vs. Pandemic

An epidemic is defined as “an outbreak of disease that spreads quickly and affects many individuals at the same time.” A pandemic is a type of epidemic (one with greater range and coverage), an outbreak of a disease that occurs over a wide geographic area and affects an exceptionally high proportion of the population. While a pandemic may be characterized as a type of epidemic, you would not say that an epidemic is a type of pandemic.

I believe an epidemic is localized like just in one town but a pandemic spreads around the world.
