I think this is correct but haven't been able to find an official definition beyond the dictionary and wikipedia so far... If you find something reliable please can you drop in replies?
Dunno what be "official"; some United States statutory definition? I have a copy of Webster's Third New International Dictionary, copyright 1966, and looked it up there. Does the definition change every year or so as some commenters suggest?
It was a pandemic. Lethality was not part of the definition in 1966.
