When the great influenza pandemic started in Haskell County, Kansas, in January
1918 people lived in relatively geographically isolated regions. It was a rural
community with farmers tending to raising chickens, pigs and cattle. There
wasn’t the prevalence of mass transportation in the form of cars, planes, and
buses that exist today. Rarely did a farmer travel to the city. There simply was
no incentive for frivolous travel; transportation over long distances was
difficult and tedious, Roads were unpaved muddy obstacle courses and the
horsepower one relied for locomotion was from the real thing.
The influenza epidemic that struck Haskell County that January was unusually
virulent. Adults who were normally safe from morbidity of the flu suddenly
succumbed to the virus-- often dying from pneumonia within days of its onset. By
March, the rash of deaths had petered out and would have gone unnoticed if it
hadn’t been for the intervention of a little conflict that spilled from the
furthest reaches of the Austrian Empire to the rest of the earth: World War One.
Suddenly, entire communities of farmers joined up for the patriotic war,
traveling for training in massive, tented army camps. The destination for the
men of Haskell County was the Fort Riley complex in Kansas. There, in camp
Funston, the fist cases of this new influenza strain appeared in the first weeks
of March. The virus spread rapidly. First, it struck the closely quartered men
in the gigantic tent cities of army training camps. Within weeks it appeared in
the surrounding towns and cities. As the soldiers were shipped overseas to the
French port of Brest, the virus accompanied the soldiers, rapidly infecting
entire cities in its wake, striking down their healthiest inhabitants.
The symptoms started like a bad cold: first a cough, runny nose and a headache.
Then, a fever ensued followed by upper respiratory congestion, a racing
heartbeat and difficulty breathing. If one was unlucky, (and 50 million people
were), the disease progressed to fatal pneumonia. This pneumonia was
particularly vicious: people literally would drown in their own fluids as lungs
rapidly lost the ability to exchange oxygen while the victim would turn a
cyanotic blue. The brevity of the time from the first sniffle to the writhing
death rattles was horrendously short. There were eyewitness accounts of people
taking the New York Subway seemingly in good health upon boarding and then dying
in a congested suffocating fury with blood pouring from every orifice by the
time their car had reached the end of the line.
It was truly a dangerous time to be out in public. People who did venture
outside would cover their faces with handkerchiefs in the futile hope that they
were somehow protected from this vile plague. They were not. Instead, entire
communities were decimated. For example, the hamlet of Brevig Mission, Alaska
lost 85% of its population over the age of 16. Isolation of the population was
the only affective measure to slow down the progression of spread. This rarely
happened. In India alone, 12 million people died. In the city of Philadelphia,
against the better judgement of protesting physicians, politics prevailed when
the public health director allowed a half a million strong rally for war bonds
took place. Within days, more than 500,000 Philadelphians succumbed to the
virus.
What made the influenza virus of 1918 so Virulent? For a long time no one knew.
It wasn’t until the late 1990's, under the strictest of secrecy, that a
genetic sequence of the virus was reconstructed. Using PCR technology, the
virus’ RNA fragments were retrieved from the Alaskan victim’s lungs. It was
the geography that played an important role in preserving the residual evidence
of this modern day plague. The victims were buried in permafrost which retarded
the decomposition of the virus’ genetic material.
In comparison with the genetic material of current avian flu viruses, it was
found that there had been a mutation of the Hemagglutinin protein. It is this
protein that allows the virus to attach to the cells of the infected host in
order to invade the cells and begin replicating. Normally, through eons of
exposures to similar proteins, humans are able to have a selective immune
response to fight the virus. However, in the case of the 1918 pandemic, the
virus’ hemagglutinins along with other proteins were so foreign and at the
same time so effective in invading cells, the human body simply could not cope
with an infection.
Once infected, a generalized defense would be mounted by the victim’s body. An
inflammatory protein called cytokines would be produced by the host’s body
which is normal in any inflammatory response to infection. However, in this
case, a massive storm of cytokines would be evoked by the virus’ unique amino
acid sequence. People would drown from the fluid caused by this cytokine
onslaught, which in turn generated leakage of the weeping endothelial cells that
line the lung. In other words, there would be a situation akin to Cholera of the
Lungs.
We are faced with same type of virus today. It is termed the H5N1 virus.
Remember that name because you are going to be hearing it repeatedly. It is only
a matter of time before some Asian who lives with livestock in their abode will
be simultaneously infected with human influenza and avian H5N1 flu. Then the
virus will incorporate the genes (from the human influenza) necessary to make
transmission from human to human. This new hybrid virus will be particularly
contagious. Then all hell will break loose.
The H5N1 strain has already killed millions of chickens in Asia. It is
particularly virulent in humans as well. It kills at least 33% of the people who
are infected it. What is worse is the fact that it has a long incubation period
in water fowl. In ducks, who apparently can carry the virus without getting
sick, the virus is spread through its digestive system, polluting the water for
up to 17 days after being infected.
When this outbreak occurs -it’s not a question of “if” only ”when”- it
will spread much more rapidly than the 1918 pandemic. It is estimated that more
than 150 million people will die. This is due to the fact that during the human
latency period a person can circle the globe while shedding the virus from one
unsuspecting victim to another. It will spread exponentially like nuclear
fission reaction. There will be no sanctuary.
