Oh and the reason it’s called the Spanish flu:

Interestingly, it was during this time that the Spanish flu earned its misnomer. Spain was neutral during World War I and unlike its European neighbors, it didn’t impose wartime censorship on its press. In France, England and the United States, newspapers weren’t allowed to report on anything that could harm the war effort, including news that a crippling virus was sweeping through troops. Since Spanish journalists were some of the only ones reporting on a widespread flu outbreak in the spring of 1918, the pandemic became known as the “Spanish flu.”
