Some 500 million people or one-third of the worlds population became infected with the 1918 Spanish flu. Few noticed the epidemic in the midst of the war.

The Spanish flu continued to appear mutating and acquiring genetic material from other viruses For example the 2009 flu had genetic elements from earlier viruses so older individuals were.

Spanish flu mutation. In 1918 something similar may have happened. The Spanish flu virus of 19181919 had the worst qualities of both which is why it killed more people than World War I did. The Spanish influenza pandemic killed over 20 million people in 1918 and 1919 making it the worst infectious pandemic in history.

Likewise strains of coronavirus are known to mutate relatively easily. However a first wave of influenza appeared early in the spring of 1918 in Kansas and in military camps throughout the US.
