The flu arrived as a great war raged in Europe, a conflict that would leave about 20 million people dead over four years.

In 1918, the flu would kill more than twice that number — and perhaps five times as many — in just 15 months. Though mostly forgotten, it has been called “the greatest medical holocaust in history.”

Experts believe between 50 and 100 million people were killed. More than two-thirds of them died in a single 10-week period in the autumn of 1918.

Never have so many died so swiftly from a single disease. In the United States alone, it killed about 675,000 in about a year — the same number who have died of AIDS in nearly 40 years.

As the country muddles through a particularly nasty flu season — one that the Centers for Disease Control says has killed 24 children in the first three weeks of January and 37 since the start of the flu season — the 1918 nightmare serves a reminder. If a virulent enough strain were to emerge again, a century of modern medicine might not save millions from dying.

“You think about how bad it was in 1918, and you think surely our modern medical technology will save us, but influenza is the Hollywood movie writer’s worst nightmare,” said Anne Schuchat, CDC’s deputy director, at a recent seminar on the 1918 pandemic. “We have many more tools than we had before, but they are imperfect tools.”

One hundred years ago, a third of the world’s population came down with what was dubbed the Spanish flu. (It got its name when the king of Spain, Alfonso XIII, his prime minister and several cabinet ministers came down with the disease.)

The flu brought life to a standstill, emptying city streets, closing churches, pool halls, saloons and theaters. Coffin makers couldn’t keep up with demand, so mass graves were dug to bury the dead. People cowered behind closed doors for fear they would be struck down.

In Philadelphia, news stories described priests driving carts through the streets, encouraging people to bring out the dead so that they might be buried.

In New York there were accounts of people feeling perfectly healthy when they boarded the subway in Coney Island and being taken off dead when they reached Columbus Circle.

Entire families succumbed.

In Tyler County, West Virginia, John Linza, his wife and two of their sons died on the same day. Two other sons died just days before them. The last Linza, an infant, died the day after his parents.

In the southwestern tip of Virginia, J.W. Trent, his wife and two sons fell ill. They were preceded in death by all four of their young daughters — Hattie, Mary, Ellen and Ruby.

In 10 weeks, the flu killed 20,000 in New York City and produced 31,000 orphans.

There is debate among historians about where the flu first surfaced — did it come from China or a British encampment in northern France or rural Kansas? But it spread worldwide practically overnight.

By the end of November, 50,000 had died in South Africa, where at its peak flu killed 600 people each day. In Egypt, the death count reached 41,000 in Cairo and Alexandria by January. In Tahiti, trucks roamed the streets of Papeete to collect the dead, and great funeral pyres burned day and night to incinerate the bodies.

Normally the most vulnerable to influenza are infants, whose immune systems are not yet up to the test, and the elderly, whose ability to fight disease?diminishes with age. In 1918, more than half the people it killed were in the prime of their lives.

Many died within hours, turning blue from lack of oxygen as they coughed foamy blood up from their lungs and bled from the nose, ears and eyes.

The Spanish flu infected the upper respiratory tract and then dove deep into the lungs with viral or bacterial pneumonia. How did it kill so many young healthy adults? Their immune systems attacked the influenza invader with such force that it killed them.

One Army doctor, quoted by historian John M. Barry, author of the bestseller, “The Great Influenza,” described the scene at a base hospital in Massachusetts:

“When brought to the [hospital] they very rapidly develop the most vicious type of pneumonia that has ever been seen. Two hours after admission they have the Mahogany spots over the cheek bones, and a few hours later you can begin to see [the blueness] extending from their ears and spreading all over the face. … It is only a matter of a few hours then until death comes. … It is horrible.”

Yet President Woodrow Wilson was unwilling to take any action that would compromise the war effort.

In early October, even as the disease was sweeping through military bases, killing soldiers and sailors by the thousands, U.S. Surgeon General Rupert Blue warned against rushing to see doctors with “mild cases of influenza.”

“The present generation,” Blue said, “has been spoiled by having had expert medical and nursing care readily available.”

Cowering in their homes
Then as now, the catch phrase was “a touch of the flu.” The flu rolled in every winter, enveloping people in a fog and fever that lasted a few days and lingered for a week or two. It was something to be endured, but not many people died from it.

And so it began in 1918.

To comprehend what came next — and why it is possible that a deadly strain of influenza could rear up 100 years later to kill tens of millions — requires an understanding of the disease.

The world’s most successful vaccinations against measles, polio, tetanus and small pox generally work in the same way. They introduce a minuscule amount of the disease so that if it ever arrives in full-blown form, the body will recognize and neutralize it with an immune system counter attack.

Influenza, however, never gives the immune system a stable target. Instead, it can transform itself into something that appears innocent to the white blood cells and enzymes intended to wage war against it.

That explains why a vaccine against the flu is a hit-or-miss proposition, based on the best guess of scientists about what flu strains are most likely to emerge six months later. The CDC estimates flu vaccines will be about 30 percent effective against this year’s predominant strain, H3N2, but about 60 percent effective against the other influenza A strain, H1N1, and about 50 percent effective against influenza B viruses.

In 1918 there were no flu vaccinations, and it would not have mattered anyway. After the “touch of the flu” that proved deadly only here and there during the spring, the influenza apparently mutated into a killer.

By early autumn the public face of America and the Western world had a gauze mask on it. People wore them to church, the military marched in them, police posed for photos in them and doctors wore them to visit patients. In Seattle, anyone who tried to board street cars without a gauze mask was arrested.

The masks served little purpose. The fine spray of a sneeze creates a cloud of more than half a million virus particles, and the virus can live for hours on any hard surface where they settle.

Four women who gathered to play bridge in Albuquerque in November prudently wore six-ply cloth masks. Three of them were dead the next day.

The frightening spread of the disease led to official and self-imposed quarantines.

Schools, theaters, bars and other gathering places were ordered closed. Mothers were told their children should be confined to their own yards. In New York, officials so feared transmission on overcrowded subways that they ordered people to work staggered shifts.

People cowered from contact with anyone who might carry the disease. A doctor in Philadelphia spoke of driving from the hospital to his suburban home without seeing another person or vehicle on the streets.

Many flu victims died in their homes of starvation, and not the disease, because they were too weak to seek food and no one dared bring it to them.

We are still vulnerable
A century later, science has revolutionized the medical profession, producing miracle drugs and surgical procedures that no one could have imagined in 1918.

But when Thomas Frieden stepped down as head of the CDC last year he was asked in an interview what keeps him awake at night.

“We always worry about pandemic influenza because this has the potential to kill so many people,” he said. “We stockpile antivirals for an emergency. But much more is needed to both track influenza better around the world and develop a better flu vaccine.”

A “touch of the flu” kills up to 646,000 people worldwide each year, sometimes as many as 56,000 of them in the United States. Since 1918, there have been three flu pandemics. (An epidemic is when an infectious disease spreads rapidly to many people. A pandemic is a global disease outbreak).

“Obviously, we still have no control over the virus,” said Barry, the historian who gave the keynote speech in 2004 when the National Academies of Science gathered to discuss pandemic influenza. “In a lot of ways, we’re arguably as vulnerable, or more vulnerable, to another pandemic as we were in 1918 because there’s more economic interdependence.”

A universal vaccine — one that will protect against every possible flu strain — isn’t expected to emerge any time soon.

“One hundred years after the lethal 1918 flu we are still vulnerable,” warned Anthony S. Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), at a Smithsonian seminar on the 1918 pandemic. “Without a universal vaccine, a single virus would result in a world catastrophe.”

Could a 1918 scenario could repeat itself?

“It’s clear that we have a much greater capacity to respond, and we would expect to respond more effectively to a 1918-like virus, but we could have [a strain] more transmissible and more severe,” Daniel Sosin, the CDC’s deputy director for preparedness said at a recent Council on Foreign Relations forum.

One of the scant protections against another pandemic is the global reporting system that tracks emerging strains. If a 1918-like flu were to present itself, the system would, at least, alert the rest of the world to its deadly potential.

Jeffery K. Taubenberger and Ann Reid were the first researchers to sequence the genome of the influenza virus that caused the 1918 pandemic.

“The most important thing to do is not just to understand 1918 as a historical phenomenon,” said Taubenberger, an NIAID virologist, “but as an example of what could happen in the future.”

Artemis Astronauts to Study the Moon’s Surface Using Mainly Their Eyes

More than 50 years after humans first flew around the Moon, Artemis astronauts will repeat the feat on Monday and use the most basic instrument to study it: their eyes.

Despite the technological advancements since the Apollo missions, NASA still relies on the eyesight of its astronauts to learn more about the Moon.

"The human eye is basically the best camera that could ever or will ever exist," Kelsey Young, the lead scientist for the Artemis 2 mission, told AFP.

"The number of receptors in the human eye far outweighs what a camera is able to do."

Although modern cameras may be superior to human eyesight in some respects, "the human eye is really good at color, and it's really good at context, and it's also really good at photometric observations," Young said.

Humans can understand how lighting changes surface details, like how angled lighting reveals texture but reduces visible color.

In just the blink of an eye, humans can detect a subtle color shift and understand how lighting changes the contours of a landscape like the Moon's surface, details which are scientifically useful but difficult to ascertain from photos or videos.

Artemis 2 astronaut Victor Glover, who pilots the Orion spacecraft, said before liftoff this week that eyes were a "magical instrument."

- Field scientists -

To ensure they made the most of their proximity to the Moon, the four Artemis 2 crew members underwent more than two years of training.

Young said the goal was to turn the astronauts into "field scientists" via a combination of classroom lessons, geological expeditions to Iceland and Canada, and multiple simulated flybys of the Moon, just like the mission they are on.

The three American astronauts -- commander Reid Wiseman, pilot Glover and mission specialist Christina Koch -- along with Canadian astronaut Jeremy Hansen, all had to memorize the Moon's "Big 15," or the 15 features of the Moon that will allow them to orient themselves.

Using an inflatable Moon globe, they practiced seeing how the angle of the sun changed the colors and textures of the lunar surface, honing their observation and note-taking skills for the big moment.

"I can tell you, they are excited and they are ready," Young said with a smile.

- 'About the size of a basketball' -

The Artemis astronauts' mission is to study certain lunar sites and phenomena as part of 10 objectives chosen by NASA and ranked in priority order based on scientific interest.

During the Moon flyby, which will last for several hours, the crew will have to observe the celestial body with their naked eyes, along with cameras they have on board.

Noah Petro, head of NASA's planetary geology lab, told AFP that the Moon will look to the astronauts "about the size of a basketball held at arm's length."

"The question I'm most interested in is, are they going to be able to see color on the lunar surface," Petro said.

"I don't mean rainbow colors, but you know, dark browns or tan colors because that tells us something about the composition, and that tells us something about the history of the Moon."

David Kring of the Lunar and Planetary Institute told AFP he is not expecting any earth-shattering discoveries because of the multiple lunar probes and high-resolution images of the Moon taken since the Apollo missions.

Nevertheless, "having astronauts describing what they're seeing... That is an occurrence that at least two generations of people on Earth have never heard before," he said.

The Artemis 2 flyby will be broadcast live by NASA, save for a period for when the spacecraft is behind the moon.

"Just listening to their practice descriptions in the mission simulations... It brings chills up my arms," Young said.

"I am absolutely confident that these four people are going to deliver some incredible descriptions."

The Artemis 2 astronauts have passed the halfway point between Earth and the Moon on Saturday as they sped toward a planned lunar flyby, with NASA releasing initial images of Earth taken from inside the Orion spacecraft.

Astronaut Christina Koch said the crew had a collective "expression of joy" upon being told of the milestone, which was hit around two days, five hours and 24 minutes after the spacecraft blasted off from the Kennedy Space Center in Florida, AFP said.

"We can see the Moon out of the docking hatch right now, it is a beautiful sight," Koch said around 11 pm (0400 GMT) Friday, according to the space agency's official live broadcast.

NASA's online dashboard showed early Saturday that the Orion spacecraft carrying the astronauts was more than 229,000 kilometers (142,000 miles) from Earth.

The space agency earlier released images from Orion that included a full portrait of Earth, featuring its deep blue oceans and billowing clouds.

After a flurry of high-stakes activity including a dramatic blast-off and an engine firing that catapulted them on their historic trajectory to circle the Moon, the four astronauts aboard were able to catch their breath, even as they continued to perform a variety of equipment checks and tests.

"There has been a tremendous amount of disbelief for me, it's just so extraordinary," said Canadian Jeremy Hansen during a Q&A session with press late Thursday.

"I really like it up here," said Hansen, on his first ever journey to space. "The views are extraordinary."

"It's really fun to be floating around" in zero gravity, he added. "It just makes me feel like a little kid."

Hansen is on the crew with Americans Koch, Victor Glover and Reid Wiseman.

They are due to loop around the Moon early next week -- a feat not accomplished in more than 50 years.

NASA official Lakiesha Hawkins praised the photographs taken by commander Wiseman, calling them "amazing" during a briefing Friday.

"We continue to learn all about our spacecraft as we operate it in deep space with crew for the first time," Hawkins said.

"It's important to remind ourselves of that as we learn a little bit more day by day."

- 'Great spirits' -

Friday's to-do list includes a CPR demonstration and medical kit checks, the US space agency said, as well as preparation for the scientific observations they'll need to document when they are closest to the Moon on day six of their journey.

NASA officials reported Friday that all systems were performing well, and that the astronauts were in "great spirits" and had spoken to their families.

The next major milestone of the approximately 10-day journey is expected overnight Sunday into Monday, at which point the astronauts will enter the "lunar sphere of influence" -- when the Moon's gravity will have stronger pull on the spacecraft than Earth's.

If all proceeds smoothly, as Orion whips around the Moon the astronauts could set a record by venturing farther from Earth than any human before.

"There is nothing normal about this," said mission commander Wiseman late Thursday.

"Sending four humans 250,000 miles away is a Herculean effort, and we are now just realizing the gravity of that."

The Artemis 2 mission is part of a longer-term plan to repeatedly return to the Moon, with the goal of establishing a permanent lunar base that will offer a platform for further exploration.

Four Artemis astronauts were zooming towards the Moon late Thursday after a major engine firing, a milestone that commits NASA to the first crewed lunar flyby in more than half a century.

With enough thrust to accelerate a stationary car to highway driving speed in less than three seconds, the Orion capsule engine blasted the astronauts on their trajectory towards the Moon, which they now will loop as part of the 10-day Artemis 2 mission, reported AFP.

In the moments that followed what the US space agency dubbed a "flawless" firing that lasted just under six minutes, astronaut Jeremy Hansen said that "humanity has once again shown what we are capable of."

The astronauts said they were "glued to the window" taking pictures, and later passed a floating microphone back and forth as they took questions from US television networks.

They said the spacecraft was a little chilly and they were still making it a home, but the crew was all smiles.

"There's nothing that prepares you for the breathtaking aspect of seeing your home planet both lit up bright as day, and also the Moon glow on it at night with the beautiful beam of the sunset," said Christina Koch.

Thursday's nudge came one day after the enormous orange-and-white Space Launch System (SLS) rocket carrying the Orion capsule launched from Kennedy Space Center in Florida for the long-anticipated journey around the Moon.

The astronauts are now on a "free-return" trajectory, which uses the Moon's gravity to slingshot around it before heading back towards Earth without propulsion.

"From this point forward, the laws of orbital mechanics are going to carry our crew to the Moon, around the far side and back to Earth," NASA official Lori Glaze said.

The astronauts are wearing suits that also serve as "survival systems" -- in the unlikely case of a cabin depressurization or leak, they'll maintain oxygen, temperature controls and the correct pressure for up to six days.

The astronauts -- Americans Reid Wiseman, Victor Glover and Koch along with Canadian Hansen -- spent their first hours in space performing checks and troubleshooting minor problems on the spacecraft that has never carried humans before, including a communications issue and a malfunctioning toilet.

Queried on the toilet situation, Koch said she was "proud to call myself the space plumber.

"I like to say that it is probably the most important piece of equipment on board," she said. "So we were all breathing a sigh of relief when it turned out to be just fine."

- 'Herculean' -

Crewmembers also had their first workouts of the mission on the spacecraft's "flywheel exercise device" -- each astronaut will carve out 30 minutes a day for fitness, a bid to minimize the muscle and bone loss that happens without gravity.

The 10-day mission is aimed at paving the way for a Moon landing in 2028.

Artemis 2 marks a series of historic accomplishments: sending the first person of color, the first woman and the first non-American on a lunar mission.

If all proceeds smoothly, the astronauts could also set a record by venturing farther from Earth than any human before.

"There is nothing normal about this," said Wiseman. "Sending four humans 250,000 miles away is a Herculean effort, and we are now just realizing the gravity of that."

The Artemis 2 mission is part of a longer-term plan to repeatedly return to the Moon, with the goal of establishing a permanent base that will offer a platform for further exploration.

The current era of American lunar investment has frequently been portrayed as an effort to compete with China, which aims to land humans on the Moon by 2030.

Asked about division closer to home and what message they had for Americans, Glover said from his vantage point, "You look amazing. You look beautiful."

"From up here, you also look like one thing," he added. "We're all one people."
