interesting facts about: history
The 1918 flu pandemic was an extremely deadly disease, the first of the two pandemics including H1N1 influenza virus. In 1918-1920 it infected more than 500 million people across the world, including further Pacific islands and the Arctic, and killed up 100 million of them, or three to five percent of the world's humanking population. This flu was one of the deadliest natural disasters in human history, and it took more live than even both world wars.
Most flu outbursts disproportionately killed youthful, old people, or already depleted patients. Nevertheless, the 1918 pandemic flu predominantly killed in advance healthy young adults. Modern investigations, using virus taken from the bodies of frozen victims of the influenza, has concluded that the virus kills through a cytokine storm (reaction of the immune system). The strong immune reactions of young people damaged the body, whereas the weaker immune systems of children and middle-aged adults resulted in fewer deaths among those groups of ages.
Epidemiological and historical materials are inadequate to distinguish geographic origin of the pandemic. It was implicated in the outburst of encephalitis lethargica in the early 1920s.
To maintain confidence, wartime censors minimized first reports of illness and mortality in European contries, such as Germany, Britain, France, and the even United States. But papers continued to report the epidemic's effects in neutral Spain (such as the grave illness of Spanish King Alfonso XIII), creating a false impression of the Spain especially hard situation. Thus the pandemic's gained nickname Spanish flu and today is most known.
The worldwide mortality rate from the 1918 to 1919 pandemic is not known, but an estimated from 10% to 20% of the infected people died. With about a third of the global population infected this ratio means 3% to 6% of the entire world population died because of… flu! Influenza may have killed more than 25 million people in its first 4 months. Older rates say it killed 40–50 million people, while current estimates say about more than 100 million people worldwide died. Spanish pandemic killed more people in 24 weeks than AIDS has killed in last 26 years and more in a year than the Black Death killed in 100 years!
