Epidemic and Me

 

What is Epidemic ?

A widespread occurrence of an infectious disease in a community at a particular time.

Whilst “endemic” is the baseline level of a disease, an epidemic refers to the, often sudden, rise in the number of cases of a particular disease above the normal endemic level. The number of cases varies according to the disease-causing agent, and the size and type of previous and existing exposure to the agent. The precise definition will depend on the literature in which it is presented, and there is no established threshold for the number of cases, duration of disease or geographical area affected for something to be deemed an epidemic. Seasonal influenza in people is often described as a seasonal epidemic.
