epidemic vs pandemic vs endemic — all about disease 'among the people,' separated by reach. Endemic = always present in one region (malaria is endemic to the tropics). Epidemic = a sudden outbreak in a community. Pandemic = an epidemic that has spread across countries and continents. Scale: endemic < epidemic < pandemic.
