March 11, 1918 Plague

“Antigenic Shift” occurs when two or more DNA strands combine, instantaneously forming a new virus sub-type. Like the dealer at some giant, cosmic poker table, this process may deal us a pair of twos. Occasionally, fate deals us aces & eights. The death hand.

In the world of virology, “Antigenic Drift” describes changes which happen slowly, the random mutation of virus DNA which takes place over months, or years. It’s why we get a new flu vaccine every year, even though there’s already some level of “herd immunity”.

Antigenic shift vs antigenic driftWhen the “Great War” broke out in 1914, US Armed Forces were small compared with the mobilized forces of the European powers. The Selective Service Act, enacted May 18, 1917, authorized the federal government to raise an army for the United States’ entry into WWI. Two months after the American declaration of war against Imperial Germany, a mere 14,000 American soldiers had arrived “over there”. Eleven months later, that number stood at well over a million.

General “Black Jack” Pershing insisted that his forces be well trained before deployment. New recruits poured into training camps by the tens of thousands, while somewhere, some microscopic, chance recombination of surface proteins created a new virus, novel to nearly every immune system, in the world.

Private Albert Gitchell reported to the hospital, complaining of cold-like symptoms of sore throat, fever and headache. By noon, more than 100 more had reported sick with similar symptoms.

Ordinary flu strains prey heavily on children, elderly, and those with compromised immune systems. Not this one. This flu would kick off a positive feedback loop between small proteins called cytokines, and white blood cells. This “cytokine storm” resulted in a death rate for 15-34 year olds 20 times higher in 1918, than in previous years. Perversely, it was their young and healthy immune systems that were most likely to kill them.

Physicians described the most viscous pneumonia they had ever seen, death often coming within hours of the first symptoms. There’s a story about four young, healthy women playing bridge well into the night. By morning, three were dead of influenza.

In 1918, children skipped rope to a rhyme:

“I had a little bird,
Its name was Enza.
I opened the window,
and in-flu-enza”.

In the trenches, the flu cut down combatants on every side. “Operation Michael”, the final, no holds barred German offensive which would determine the outcome of the war, launched from the Hindenburg line in March. Crown Prince Rupprecht wrote in August, “poor provisions, heavy losses, and the deepening influenza have deeply depressed the spirits of men in the 3rd Infantry Division”.

Some sources report as many as half the Americans killed in WWI, died of the flu.

The parades and parties following the cease fire of November 11 threw gas on the flames.  Millions more contracted the flu and thousands more died. President Wilson himself fell ill, while participating in 1919 treaty negotiations in Versailles.  From a public health point of view, the end of war was a disaster.

Around the planet, the Spanish flu infected half a Billion people. A third of the population of the entire world, at that time. Estimates run as high 50 to 100 million killed. For purposes of comparison, the “Black Death” of 1347-51 killed 20 million Europeans.

History has a way of swallowing some events whole, like they never happened. Today, the Spanish flu is all but overshadowed by the War to end all wars.  Even though in the end, the flu pandemic of 1918-19 proved a far deadlier adversary, than the war itself.

 

A Trivial Matter

In the 17th century, it was cheaper to import some things from England, than to produce them here.  The first bible printed in the future United States came off the press in 1661 in the Algonquin language, a tongue all but extinct in this country, today.
