1918 Pandemic (H1N1 virus)

The 1918 influenza in numbers

The number of deaths was estimated to be at least 50 million worldwide with about 675,000 occurring in the United States.
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.

1918 Pandemic (H1N1 virus)

The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin.
We don't really know he virus originated, it spread worldwide during. It is estimated that about 500 million people or one-third of the world’s population became infected with this virus.

The 2009 H1N1 outbreak in numbers

From April 12, 2009 to April 10, 2010, CDC estimated there were 60.8 million cases (range: 43.3-89.3 million), 274,304 hospitalizations (range: 195,086-402,719), and 12,469 deaths (range: 8868-18,306) in the United States due to the (H1N1)pdm09 virus.
Additionally, CDC estimated that 151,700-575,400 people worldwide died from (H1N1)pdm09 virus infection during the first year the virus circulated.

The 2009 H1N1 Pandemic

Though the 2009 flu pandemic primarily affected children and young and middle-aged adults, the impact of the (H1N1)pdm09 virus on the global population during the first year was less severe than that of previous pandemics.
The (H1N1)pdm09 virus was very different from H1N1 viruses that were circulating at the time of the pandemic. Few young people had any existing immunity (as detected by antibody response) to the (H1N1)pdm09 virus, but nearly one-third of people over 60 years old had antibodies against this virus, likely from exposure to an older H1N1 virus earlier in their lives.

The origins of the "Spanish" flu

The so-called Spanish flu did not originate in Spain. The geographic origin of the flu is debated to this day, though hypotheses have suggested East Asia, Europe, and even Kansas.
The influenza pandemic from 1918 got this name most likely because of the WWI context: The major countries involved in the war were keen to avoid encouraging their enemies, so reports of the extent of the flu were suppressed in Germany, Austria, France, the United Kingdom and the U.S. By contrast, neutral Spain had no need to keep the flu under wraps. That created the false impression that Spain was bearing the brunt of the disease.

The end of mankind

The 1918 flu spread rapidly, killing 25 million people in just the first six months. This led some to fear the end of mankind and that the whole thing was caused by a form of super-virus.
Recent studies show that the high death rate can be attributed to crowding in military camps and urban environments, as well as poor nutrition and sanitation, which suffered during wartime.

Disease Event Classification

Epidemiology is the branch of medicine that handles the following:

  • Incidence: the occurrence of a disease over a specified period.
  • Prevalence: how many people are affected within a population.
  • Control of diseases: an appropriate public health response.

Two measurable factors mostly define the level of disease occurrence:

  • The pattern and speed by which a disease moves.
  • The size of the susceptible population.
The terms an epidemiologist use
  • Sporadic refers to a disease that occurs infrequently or irregularly.
  • Cluster refers to a disease that occurs in larger numbers even though the actual number or cause may be uncertain.
  • Endemic refers to the constant presence and/or general prevalence of a disease in a geographic population.
  • Hyperendemic refers to persistent, high levels of disease well above what is seen in other populations.
  • Epidemic refers to a sudden increase in the number of cases of a disease above what is normally expected.
  • Outbreak is the same as an epidemic but is often used to describe a more limited geographic event.
  • Pandemic refers to an epidemic that has spread over several countries or continents, usually affecting a large number of people.

The false choice

“Save the economy or save lives” is a false choice.
A group of economists published a paper on the 1918 flu outbreak. Their findings revealed:

  • Early and aggressive interventions saved lives and triggered a faster rebound, such as job growth and banking assets.
  • Without a healthy population, there can be no healthy economy.

The hope is for a deep, short recession, to show that people have shut the economy down to limit the spread of disease.

A living wage

Asking millions of able-bodied workers to stop working creates a crisis of unemployment.

During this time, the U.S. is expanding unemployment benefits and are also delaying tax filing. In northern-European countries, the government is directly paying businesses to maintain their payrolls to avoid mass layoffs and furloughs.

Preventing system overload

Staying home during the pandemic helps prevent health systems from being overloaded.
Overloading hospitals can likely be averted with protective measures like closing schools, canceling mass gatherings, working from home, self-quarantine, self-isolation, avoiding crowds. All these keep the virus from spreading fast.
