Difference between a Pandemic and Epidemic?

Welcome to another post on my blog. Today, in Chemicals and Chaos, I move on from independent tasks to the 'Black Death'. We had an introduction explaining some keywords relating to the 'Black Death'; Epidemic, Plague and Outbreak.

After that, we were given a question to answer, 'What is the difference between a Pandemic and an Epidemic?'

A pandemic is a disease which is spread all over the world, such as the COVID-19 pandemic. Whereas an epidemic is a disease which is spread in a community, area or a country, such as the West African Ebola virus epidemic in 2013-2016.
