Why experts are certain another influenza pandemic will occur

It's been 100 years since the world's last deadliest flu pandemic. Experts warn that another one is inevitable, but are we ready?

  • 100 years ago, the Spanish Flu killed over 50 million people.
  • According to the Centers for Disease Control and Prevention, over 80,000 Americans died of the flu last winter.
  • Experts stress that the world needs to take precautions and prepare for the next pandemic.

Humans have been fighting the influenza virus for millenia. We've discovered new strains throughout the years and also devised greater methods for eradicating them along the way. But on the 100th year anniversary of the Spanish Flu pandemic, it's more important now than ever that we look back at one of the deadliest pandemics the world has ever faced.

Our global village is tied together in such a way that it makes containing a localized infection nearly impossible. Through air, freight-train and onwards through land and sea, the most populous and densely packed cities in the world are now just a stone's throw away.

The possibility that another epidemic could sweep through the world and claim millions of lives is no surprise to the experts. After all, it's happened before.

History of the Spanish flu pandemic of 1918 

Let's look back at how the Spanish flu first got its start.

It was the fall of 1918 and the First Great War in Europe was just winding down. Americans had been shipped overseas and were helping assist the Allies as they fought against the Germans. Soldiers around the globe dug out and wintered through trenches in horrible and brutal conditions. They had probably thought they'd seen the worst of things by this point.

Lurking just somewhere over the horizon, however, was one of the deadliest flus the world would ever face.

Over a third of the world's population became infected. Erupting in pockets around the globe the outbreaks swept through Asia, Europe, Africa and America by bustling trade routes. Many also suspected rapid troop movement assisted in the spread of the disease. Around 675,000 Americans died of influenza during the two year pandemic.

The intensity and speed in which the pandemic struck was unfathomable at the time. With over 500 million people infected and an estimated 50 million deaths worldwide, the global death toll eclipsed even World War I casualties. The disease is not "Spanish" in origin per say, but because of wartime censorship in other countries, Spain was the first to report of the pandemic.

Our most recent flu seasons pale in comparison to the great plight wrought from the Spanish flu.

Latest trends in America’s flu seasons 

For the most part, vaccinations, antibiotics and better global hygiene has drastically reduced the effects of influenza and other associated diseases. But viruses never rest — and they never stop evolving.

Officials at the Centers for Disease Control and Prevention have estimated that a preliminary figure of last year's winter flu season was around 80,000 deaths. This figure may be revised, but it's unlikely the numbers will go down. Dr. Daniel Jernigan, a CDC flu expert, believes that the deaths were higher than usual because there are both more Americans and more elderly people now.

Luckily, Jernigan believes that next year's flu season is stacking up to be both a milder strain and also more receptive to vaccination. "We don't know what's going to happen," he said, "but we're seeing more encouraging signs than we were early last year."

While we might be all right for the upcoming flu season. Others warn that a hidden virus could jumpstart a new global pandemic.

The U.S is not ready for a major pandemic

One of the worst case scenarios in the short term, could be the release of a hidden, lethal and highly infectious flu strain that breaks out into a crowded city. According to the John Hopkins' Bloomberg School of Public Health, this would be devastating for an unprepared city that lacked a strong public health infrastructure.

A fast moving virus could hitch a ride from one city to a next and spread internationally before health officials even knew what hit humanity. Scientists at John Hopkins believe that avian influenza viruses pose the greatest risk if they evolve into deadlier strains. Amesh Adalja from the Center of Healthy Security at John Hopkins states: "In terms of pandemic potential, an avian influenza virus is thought to be a likely candidate, based on prior pandemics."

Yet, there are safeguards that didn't exist 100 years ago we can use to preemptively ward off a potential flu pandemic.

For example we can:

  • Improve vaccine research and deployment. Funding for high-priority vaccines is a must to create herd immunity.
  • Increase pandemic preparation funding. Public health officials need to be able to deal with a multiple of infected at once.
  • Create a global response network that can quickly intervene in a pandemic. For example, the World Health Organization (WHO) needs a counterpart that can take action once any kind of pandemic has been declared.

The more we do to combat these diseases now, the less risk we have for another worldwide pandemic later.

China’s artificial sun reaches fusion temperature: 100 million degrees

In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.

Scientists reverse hair loss by making scalp "smell" sandalwood

It turns out the human scalp has an olfactory receptor that seems to play a crucial role in regulating hair follicle growth and death.

  • Scientists treated scalp tissue with a chemical that mimics the odor of sandalwood.
  • This chemical bound to an olfactory receptor in the scalp and stimulated hair growth.
  • The treatment could soon be available to the public.

Why a federal judge ordered White House to restore Jim Acosta's press badge

A federal judge ruled that the Trump administration likely violated the reporter's Fifth Amendment rights when it stripped his press credentials earlier this month.

WASHINGTON, DC - NOVEMBER 16: CNN chief White House correspondent Jim Acosta (R) returns to the White House with CNN Washington bureau chief Sam Feist after Federal judge Timothy J. Kelly ordered the White House to reinstate his press pass November 16, 2018 in Washington, DC. CNN has filed a lawsuit against the White House after Acosta's press pass was revoked after a dispute involving a news conference last week. (Photo by Alex Wong/Getty Images)
Politics & Current Affairs
  • Acosta will be allowed to return to the White House on Friday.
  • The judge described the ruling as narrow, and didn't rule one way or the other on violations of the First Amendment.
  • The case is still open, and the administration may choose to appeal the ruling.

Scientists just voted to change the definition of a kilogram

The definition of a kilogram will now be fixed to Planck's constant, a fundamental part of quantum physics.

Surprising Science
  • The new definition of a kilogram is based on a physical constant in quantum physics.
  • Unlike the current definition of a kilogram, this measurement will never change.
  • Scientists also voted to update the definitions of several other measurements in physics.
