Which age group died the most from Spanish flu?
Mortality was high in people younger than 5 years old, 20-40 years old, and 65 years and older. The high mortality in healthy people, including those in the 20-40 year age group, was a unique feature of this pandemic.
What was the estimated mortality for the 1918 influenza pandemic?
The disease was exceptionally severe. Case-fatality rates were >2.5%, compared to <0.1% in other influenza pandemics (3,4). Total deaths were estimated at ≈50 million (5–7) and were arguably as high as 100 million (7). The impact of this pandemic was not limited to 1918–1919.
Who was most at risk of contracting the Spanish flu in 1918?
Figure 1 demonstrates clearly the peculiar phenomenon during the “Spanish ‘flu” of highest proportionate increases in mortality among young adults, particularly those in their twenties and thirties. For women, these are the child-bearing years, and pregnant women were at particularly high risk of becoming infected.
What animal did the Spanish flu come from?
The predominant natural reservoir of influenza viruses is thought to be wild waterfowl (Webster et al. 1992). Periodically, genetic material from avian virus strains is transferred to virus strains infectious to humans by a process called reassortment.
Did they cure the Spanish flu?
The Spanish flu pandemic of 1918 infected an estimated 33% of the world’s population. There were no effective treatments and no widespread efforts to prevent the spread. There are some comparisons to the COVID-19 pandemic.
What is the difference between an epidemic and a pandemic?
AN EPIDEMIC is a disease that affects a large number of people within a community, population, or region. A PANDEMIC is an epidemic that’s spread over multiple countries or continents. ENDEMIC is something that belongs to a particular people or country.
How long did the plague last?
One of the worst plagues in history arrived at Europe’s shores in 1347. Five years later, some 25 to 50 million people were dead. Nearly 700 years after the Black Death swept through Europe, it still haunts the world as the worst-case scenario for an epidemic.
