The Spanish Flu, or Pandemic of 1918 (1918-1920) was a variant of avian flu which caused the death of 25-50 million people and infected nearly 500 million worldwide. In the United States, first contact with the virus occurred when returning soldiers from the First World War came back stateside, which was one of three waves which hit the country. Mortality was higher in people younger than 5 years old, as well as healthy people in 20-40 year age bracket, was a unique feature of this pandemic. With no vaccine to protect against influenza infection and no antibiotics to treat secondary bacterial infections that can be associated with influenza infections, control efforts worldwide were limited to non-pharmaceutical interventions such as isolation, quarantine, good personal hygiene, use of disinfectants, and limitations of public gatherings (community spread), which were not applied even-handed. An estimated, a third of the world's population was infected with the 1918 flu virus.
