The story
The 1918 influenza pandemic (January 1918 – December 1920; also known as the Spanish flu) was an unusually deadly influenza pandemic, the first of the two pandemics involving H1N1 influenza virus, with the second being the swine flu in 2009. The Spanish flu infected 500 million people around the world, or about 27% of the world population of between 1.8 and 1.9 billion. The death toll is estimated to have been anywhere from 17 million to 50 million, and possibly as high as 100 million, making it one of the deadliest epidemics in human history.
