One hundred years ago, what became known as the Spanish Flu, and related infections from pneumonia, claimed 23,000 lives and infected some 800,000 people in Ireland over a 12-month period (research by Dr Ida Milne). Despite this devastating loss of life and the resulting chaos, the Spanish Flu in Ireland remained an under-researched topic until the 21st century. Exciting work by scholars in recent years has managed to recover the story before it is too late. That work continues.

The National Museum of Ireland's programme The Enemy Within places the public at the forefront of Spanish Flu research and remembrance, during its centenary years.
