The Spanish flu, also known as the 1918 flu pandemic, was an unusually deadly influenza pandemic. Lasting from spring 1918 through spring or early summer 1919, it infected 500 million people – about a third of the world's population at the time. 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 pandemics in human history.
To maintain morale, World War I censors minimized early reports of illness and mortality in Germany, the United Kingdom, France, and the United States. Newspapers were free to report the epidemic's effects in neutral Spain, such as the grave illness of King Alfonso XIII, and these stories created a false impression of Spain as especially hard hit. This gave rise to the name Spanish flu. Historical and epidemiological data are inadequate to identify with certainty the pandemic's geographic origin, with varying views as to its location.
Most influenza outbreaks disproportionately kill the very young and the very old, with a higher survival rate for those in between, but the Spanish flu pandemic resulted in a higher than expected mortality rate for young adults. Scientists offer several possible explanations for the high mortality rate of the 1918 influenza pandemic. Some analyses have shown the virus to be particularly deadly because it triggers a cytokine storm, which ravages the stronger immune system of young adults. In contrast, a 2007 analysis of medical journals from the period of the pandemic found that the viral infection was no more aggressive than previous influenza strains. Instead, malnourishment, overcrowded medical camps and hospitals, and poor hygiene, all exacerbated by the recent war, promoted bacterial superinfection. This superinfection killed most of the victims, typically after a somewhat prolonged death bed.
The Spanish flu was the first of two pandemic caused by influenza the second was swine flu in 2009.When an infected person sneezes or coughs, more than half a million virus particles can spread to those nearby. The close quarters and massive troop movements of World War I hastened the pandemic, and probably both increased transmission and augmented mutation. The war may also have increased the lethality of the virus. Some speculate the soldiers' immune systems were weakened by malnourishment, as well as the stresses of combat and chemical attacks, increasing their susceptibility.
In the United States, the disease was first observed in Haskell County, Kansas, in January 1918, prompting local doctor Loring Miner to warn the US Public Health Service's academic journal. On 4 March 1918, company cook Albert Gitchell, from Haskell County, reported sick at Fort Riley, a US military facility that at the time was training American troops during World War I, making him the first recorded victim of the flu. Within days, 522 men at the camp had reported sick. By 11 March 1918, the virus had reached Queens, New York. Failure to take preventive measures in March/April was later criticised.
In August 1918, a more virulent strain appeared simultaneously in Brest, France; in Freetown, Sierra Leone; and in the U.S., in September, at the Boston Navy Yard and Camp Devens (later renamed Fort Devens), about 30 miles west of Boston. Other U.S. military sites were soon afflicted, as were troops being transported to Europe. The Spanish flu also spread through Ireland, carried there by returning Irish soldiers.
Spanish flu infected around 500 million people, about one-third of the world's population. Estimates as to how many infected people died vary greatly, but the flu is regardless considered to be one of the deadliest pandemics in history.
An estimate from 1991 states that the virus killed between 25 and 39 million people. A 2005 estimate put the death toll at 50 million (about 3% of the global population), and possibly as high as 100 million (more than 5%). However, a reassessment in 2018 estimated the total to be about 17 million, though this has been contested. With a world population of 1.8 to 1.9 billion, these estimates correspond to between 1 and 6 percent of the population.This flu killed more people in 24 weeks than HIV/AIDS killed in 24 years.
