Spanish flu
Other names

This outbreak was also commonly known as the 'great influenza epidemic', after the 'great war', a common name for World War I before World War II. French military doctors originally called it 'disease 11' (maladie onze). German doctors downplayed the severity by calling it 'pseudo influenza' (Latin: pseudo, false), while in Africa, doctors tried to get patients to take it more seriously by calling it 'influenza vera' (Latin: vera, true).

A children's song from the 1889–90 flu pandemic was shortened and adapted into a skipping-rope rhyme popular in 1918. It is a metaphor for the transmissibility of 'Influenza', where that name was clipped to the apheresis 'Enza':

I had a little bird, its name was Enza. I opened the window, and in-flu-enza.
