As cholera first tore through the Europe in the mid-19th century, people tried anything to prevent the deadly disease. Then science stepped in.

THE FRANCIS A. COUNTWAY LIBRARY OF MEDICINE, HARVARD MEDICAL LIBRARYAll the way from the Ganges River delta in India, an unwelcome visitor arrived in Europe in 1831. Its victims suffered violent cramps, vomiting, and diarrhea, along with dehydration so rapid and severe that their skin was rendered a deathly blue. Many died within hours of the first symptoms.
Cholera was one of the most devastating diseases to hit Europe in the 19th century, with a series of epidemics taking hundreds of thousands of lives. And because its cause was a mystery, people were prepared to take any measure to keep it at bay. “They tried all manner of things,” says Christopher Hamlin, a science historian at the University of Notre Dame in Indiana and author of Cholera: The Biography.
Leading theories at the time held that the disease was caught through exposure to foul or filthy air, so measures designed to repel cholera by purifying the air were particularly common, as depicted in this satirical cartoon of a woman extravagantly equipped with chlorinated lime, garlic, various herbs, and vinegar bags. “Anything that tended to change the quality of the air was plausible as a preventative measure,” says Hamlin.
But by the 1850s, this so-called “miasmatic” explanation for cholera had a challenger: the idea that the disease was caused by contaminated water. In 1854, in what is now feted as the dawn of epidemiology, British physician John Snow traced the source of an outbreak in Soho, London, to a water pump on Broad Street. When the pump handle was removed, cholera cases quickly disappeared.
The same year, Italian anatomist and germ theory pioneer Filippo Pacini identified a comma-shaped bacillus he named “Vibrio” while examining the intestinal mucosa of dead cholera victims under the microscope. His findings were largely ignored at the time, however, so it was left to the German physician-scientist Robert Koch to claim the credit for the discovery. He identified the same microbe in Egypt in 1884 and, working in India a few months later, reported that the bacilli were always found in patients with cholera, but never in those with diarrhea from other causes.
Koch’s findings did not immediately put an end to the use of air purification measures, as many still clung to the miasmatic explanation. But by the end of the 19th century, cholera was known to be caused by a microbe. The vinegar bags were on the way out, while improved sanitation and a vaccine—first developed for cholera by Waldemer Haffkine in 1892—were emerging as new methods for preventing this dreaded disease.

I'm sorry, I've not got the patience to read this. Anyone so idiotic and ignorant, they just let human sewage run through the streets, I have NO patience whatever. And I know for a fact they were doing that in mid 19th century Montreal. And they had livestock running around in it. Like pigs... In a CITY. CONFUSED? I hardly think so. Genetically too stupid to live, and mankind wouldn't have needed their progeny to carry their brain genes!
