World Health Organization Declares COVID-19 a 'Pandemic.' Here's What That Means

“This is not just a public health crisis, it is a crisis that will touch every sector,” said Dr. Tedros Adhanom Ghebreyesus, WHO director-general, at a media briefing. “So every sector and every individual must be involved in the fights.”

An epidemic refers to an uptick in the spread of a disease within a specific community. By contrast, the WHO defines a pandemic as global spread of a new disease, though the specific threshold for meeting that criteria is fuzzy. The term is most often applied to new influenza strains, and the CDC says it’s used when viruses “are able to infect people easily and spread from person to person in an efficient and sustained way” in multiple regions. The declaration refers to the spread of a disease, rather than the severity of the illness it causes.
