A disease that is an epidemic over a very large geographic region or worldwide is called

Explanation:
Understanding how we label outbreaks starts with their geographic reach. An endemic disease is always present in a population at a baseline level in a given area. An epidemic is a sudden increase in cases in a specific location. When that increased spread crosses regional, continental, or global boundaries and persists across populations, it’s called a pandemic. Epizootic refers to outbreaks in animal populations. So, for a disease that becomes widespread across very large regions or worldwide, the correct term is pandemic.
