Epidemic and pandemic have similar meanings, but there is a slight difference between the two. And that difference has to do with size.
An epidemic is a disease that affects many people at the same time and spreads rapidly through a wide geographic area. The World Health Organization has added the clarification to their definition that an epidemic is considered to happen within a region or community.
A pandemic, then, is a disease outbreak that has spread beyond a region or community. A pandemic happens when many are sick at the same time at the level of country, continent, or the whole world.
So then a disease outbreak that sickens many people at the same time across the state of Texas would be considered an epidemic, but a disease outbreak that sickens many people at the same time across the entire United States would be considered a pandemic.
