50 free Spanish Flu trivia questions with answers — history quiz, new questions added Aug 2026.
Spanish flu trivia for history readers, public-health students and anyone who lived through 2020 and wants to know how the last great pandemic played out. The quiz starts with the name: why a virus first documented in Kansas ended up blamed on neutral Spain, what the Russians, French, Germans and Brazilians called it instead, and why the WHO now lists 'Spanish flu' as an example to avoid. From there it follows the four waves: army cook Albert Gitchell at Camp Funston in March 1918, the mild spring wave that sickened three-quarters of the French army, the lethal autumn wave that turned faces blue, the Philadelphia parade that cost 12,000 lives, and the strange fact that healthy 20-to-40-year-olds died in the greatest numbers. Later rounds cover India's catastrophic toll, Western Samoa's 22 percent death rate against American Samoa's zero, the Anti-Mask League of San Francisco, the bacterium wrongly blamed, the hockey final that was cancelled, and Johan Hultin's journey to an Alaskan permafrost grave that let scientists sequence the virus in 2005. Questions run from easy to expert and every answer was checked against a reference page and carries its source. See also our World War I and pandemics quizzes.

Q 01The 1918 pandemic was caused by which subtype of the influenza A virus?
H1N1
Its descendants caused every later flu pandemic, and a novel H1N1 returned to cause the 2009 pandemic.

About a third
That was an estimated 500 million people out of 1.8 to 1.9 billion.
Q 03Why did the pandemic come to be called the 'Spanish' flu?
its neutral press reported it freely
Wartime censors in belligerent countries suppressed bad news; Spanish officials were baffled to learn other countries called it 'the Spanish grip'.
Q 04The earliest probable cases were documented in March 1918 in which US state?
Kansas
Cases in Haskell County had prompted the local doctor Loring Miner to warn the Public Health Service as early as January.
Q 05The 1918 flu is conventionally dated from Albert Gitchell's case. What was his job at Camp Funston?
an army cook
Within days 522 men at the camp had reported sick, and by 11 March the virus had reached Queens, New York.
Q 06When Pravda announced the flu's arrival in Moscow, what nickname did it use?
the Spanish lady
'Ispánka' became a common name across Russia; Poles called it the 'Bolshevik disease'.
Q 07The blue-violet cyanosis seen in dying patients gave the disease which grim nickname?
the purple death
Two mahogany spots would appear over the cheekbones and within hours the whole face turned blue as the lungs filled with fluid.

American flu
British soldiers meanwhile called it 'Flanders flu' and the Germans 'Flandern-Fieber'.

sumo wrestlers
In Senegal it was 'Brazilian flu' and in Brazil 'German flu'; almost every country blamed someone else.

a popular song from a zarzuela
'Gripe española' is now common in Spain but remains controversial there.
Q 11Virologist John Oxford argued the pandemic began at an overcrowded British army camp in which French town?
Étaples
The camp had a piggery and regular poultry deliveries, and a flu-like disease with high mortality had struck there in late 1916.
Q 12Historian Mark Humphries linked the pandemic to 96,000 labourers mobilised from which country for the Allies?
China
A 2016 study found the labourers' very low flu mortality made them an unlikely source, and pointed to circulation in Europe beforehand.
Q 13The deadlier second wave of 1918 spread by ship from Brest to Boston and which West African port?
Freetown
From Freetown it moved along the coast, rivers and railways, and South Africa received it on ships bringing home labour corps troops.
Q 21Roughly how many Americans died in the 1918-1919 flu season?
500,000 to 850,000
About 20 million of the 105 million population were infected; Native American and Alaskan communities suffered terribly.

The flu finally reached it in 1926 once the quarantine ended.

the Armistice
The second wave was mostly over by December, but a third wave followed in early 1919.
Q 17Unusually for influenza, this pandemic killed which age group in the greatest numbers?
young adults
Nearly half of US deaths were among 20-to-40-year-olds; an overreacting immune system, or 'cytokine storm', is one explanation.
Q 18Most deaths were caused not by the virus directly but by what?
bacterial pneumonia
There were no antibiotics, and common throat bacteria reached lungs damaged by the virus.
