Question: Why Did Spanish Flu Kill So Many?

Where did 1918 Spanish flu start?

While it’s unlikely that the “Spanish Flu” originated in Spain, scientists are still unsure of its source.

Why did so many die from Spanish flu?

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.

What made the 1918 flu virus so deadly?

Historians now believe that the fatal severity of the Spanish flu’s “second wave” was caused by a mutated virus spread by wartime troop movements. When the Spanish flu first appeared in early March 1918, it had all the hallmarks of a seasonal flu, albeit a highly contagious and virulent strain.

What animal did the Spanish flu come from?

Is the Spanish flu still around today?

Descendants of the 1918 influenza virus still circulate today, and current seasonal influenza vaccines provide some protection against the 1918 virus.

How did the black plague end?

How did it end? The most popular theory of how the plague ended is through the implementation of quarantines. The uninfected would typically remain in their homes and only leave when it was necessary, while those who could afford to do so would leave the more densely populated areas and live in greater isolation.

How did they stop the Spanish flu?

The most effective efforts had simultaneously closed schools, churches, and theaters, and banned public gatherings. This would allow time for vaccine development (though a flu vaccine was not used until the 1940s) and lessened the strain on health care systems.

What killed more Spanish flu or plague?

2. During the Black Death Pandemic of the 1300s, plague (Yersinia pestis) killed 75 million to 200 million people, but the pandemic lasted longer than the Spanish flu, with the deaths spread out over more years.

What was the mortality rate of the 1918 flu?

An estimated one third of the world’s population (or ≈500 million persons) were infected and had clinically apparent illnesses (1,2) during the 1918–1919 influenza pandemic. The disease was exceptionally severe. Case-fatality rates were >2.5%, compared to <0.1% in other influenza pandemics (3,4).

What was the last pandemic in the USA?
