Epidemic

The epidemiological termepidemic is defined for a condition that is normally rare in a population but in a short space of time has become widespread . It may refer to both infectious diseases (for example, Zika virus epidemic in Brazil ) but also other conditions, e.g. the obesity epidemic.

For example, when COVID-19 was first detected in Wuhan it was a new infection restricted to a few individuals, however it rapidly became epidemic as it spread throughout the city, the province and then China. As the epidemic went global it became a pandemic, which is - in essence - an extensive epidemic.

History and etymology

Epidemic is derived from the Classical Greek, ἐπί (epi) meaning "near/upon/above" and δῆμος (demos) meaning "people". From the same origin comes words like epidemiology.
