Why Is the 1918 Flu Called “Spanish”?

It killed more people in a few months than the First World War did in four years, yet it is named after a country that did nothing to cause it. The 1918 influenza pandemic is a reminder that the names we give diseases often reflect politics rather than science.

A name from the censors

In 1918, countries at war censored bad news to protect morale. Spain, which was neutral, did not. Its newspapers wrote openly about the sickness, especially when King Alfonso XIII fell ill. Readers elsewhere concluded that Spain was the centre of the outbreak. Spaniards, for their part, called it the “French flu.” The true origin remains debated, with candidate locations including a military camp in Kansas, a camp in northern France and parts of China.

The scale of the toll

Estimates of deaths range widely, from about 17 million to as many as 100 million, with 50 million often cited. The virus reached West Africa by sea in August 1918, with an early outbreak among ships in Freetown, Sierra Leone, and then moved along ports and railways. In Nigeria it spread quickly from Lagos and other trading centres inland, and researchers estimate that hundreds of thousands died, though the records are incomplete.

Choices that changed outcomes

Responses differed, and so did death rates. In the Samoan Islands, Western Samoa, then under New Zealand control, allowed an infected ship to dock and lost around a fifth of its population. American Samoa enforced a quarantine and recorded no deaths. Early decisions, honest information and local leadership mattered.

Editorial assessment

The pandemic’s name is a small error with a large lesson. Societies under stress may attach blame to places and people, and the first accounts often come from whoever speaks loudest, not from where the problem began. It is also a reminder that Africa’s experience of the 1918 pandemic, though less documented, was severe, and deserves a place in the global story rather than a footnote.
