Utah Pandemic Influenza

An influenza pandemic can occur when a non-human (novel) influenza virus changes in such a way that it is able to infect humans easily and spread easily from person to person.

These are non-human viruses that circulate in birds in parts of the world so there is little to no immunity against these viruses among people.
