The zoonotic and spatial origins of the influenza virus associated with the “Spanish flu” pandemic of 1918 have been debated for decades. Outbreaks of respiratory disease in US swine occurred concurrently with disease in humans, raising the possibility that the 1918 virus originated in pigs.

What made the 1918 flu so deadly?

While the global pandemic lasted for two years, a significant number of deaths were packed into three especially cruel months in the fall of 1918. Historians now believe that the fatal severity of the Spanish flu’s “second wave” was caused by a mutated virus spread by wartime troop movements.

The Spanish flu, also known as the 1918 flu pandemic, was an unusually deadly influenza pandemic caused by the H1N1 influenza A virus. Lasting from February 1918 to April 1920, it infected 500 million people – about a third of the world’s population at the time – in four successive waves.

How was the 1918 flu transmitted?

influenza pandemic of 1918–19: temporary hospital Influenza is caused by a virus that is transmitted from person to person through airborne respiratory secretions. An outbreak can occur if a new strain of influenza virus emerges against which the population has no immunity.
