What is the difference between an outbreak, an epidemic and a pandemic?
An epidemic (or outbreak) refers to an increase, often sudden, in the number of cases of a disease above what is normally expected in that population in that area. A pandemic is the worldwide spread of a new disease, usually affecting many people. As of March 11, 2020 the World Health Organization has made the assessment that COVID-19 can be characterized as a pandemic.
