What is a Pandemic? Is it different to an Epidemic?
A pandemic disease is one that spreads quickly over a very wide geographical area and affects a huge number of people all over the globe. An epidemic disease differs in that it would normally be confined to a smaller geographic area, such as a single country or area, and would therefore affect a lesser number of people than a pandemic would. Typically, a pandemic can occur when a highly virulent disease emerges that is new to humans but is one that spreads easily amongst them.
