A confrontation between humans and invisible 'blood-sucking monsters',
To control a mysterious and evil being
The story of the war to eradicate worms

Today, we can easily eliminate any number of parasites that may have entered our bodies by simply swallowing a single deworming pill.
But to get to this point, humans had to dig and dig again to find out the identity of the 'invisible monster' using science as a weapon.
In the early 20th century, a mysterious curse spread across the American South.
After persistent research, scientists at the time discovered that this disaster was caused by a 'blood-sucking parasite'.


This parasite was evil.
The victims of this monster were mainly the poor, children and women.
The victim, who was sucked daily from his blood by parasites that had invaded his body, gradually became thinner and weaker, and eventually his eyes became empty and he began to drag his feet.
He also ate dirt from the ground like a madman.
The families of those infected with parasites were unable to escape poverty due to lack of motivation to work, and some even died one after another.
Eventually, scientists discover the identity of this killer parasite, declare war, and launch a large-scale eradication campaign.


This book tells the true story of a medical disaster: a parasitic worm that sickened millions in the early 20th century.
A mystery nonfiction that delves into the most shocking public health issues in history.
Even now, somewhere in the world, this invisible vampire is still bringing a curse upon humanity.

Against those who deny the truth
The persistent achievements of a 'scientist'

One day, as if under a spell, people lost their strength and started eating dirt.
The media simply attributed this bizarre incident to the laziness of the poor.
But Charles Stiles, a young American parasitologist, had an intuition that something was parasitic on humans.
Styles and the scientists noticed a high incidence of the disease in rural areas and made the shocking discovery that the parasite was penetrating the skin of people who walked barefoot.
But people laughed at his suggestion that people should wear shoes and brushed aside his calls for improved toilet hygiene.
It was a more difficult fight to persuade than to uncover the truth.
Thanks to the combined efforts of scientists, doctors, and philanthropists, the war against parasites was won despite prejudice and resistance.
The author of this book is an accomplished young adult nonfiction writer, and he tells this story with suspense.
