A pandemic is a global disease outbreak. It is determined by how the disease spreads, not how many deaths it causes.

For example when a new influenza A virus emerges, a flu pandemic can occur. Because the virus is new, the human population has little to no immunity against it. The virus spreads quickly from person-to-person worldwide.

UWSP monitors pandemic conditions and has Pandemic response plans developed.
