4. Cholera
Why were there cholera epidemics in Shrewsbury in the 19th century?
During the 18th and 19th centuries towns like Shrewsbury became more crowded and poor sanitation an increasing problem. Although moves were made to clear the main streets of garbage and waste this often resulted in a detrimental effect to the side streets. The shuts, alley ways, for which Shrewsbury is well known were often filled with human refuse and waste. In these conditions the killer diseases and in particular infections spread with ever increasing ease and speed.
When did cholera first appear in Britain?On the 4th of August 1832 the first outbreak of cholera reached Shrewsbury. This was just 10 months after the disease was first recorded in Britain. Cholera was first documented in the East Indies in 1817 and is supposed to have spread across the continents finally reaching Britain in October 1831.
What is cholera?Cholera is an acute illness caused by infection of the intestine with the bacterium Vibrio cholerae. The severe form of the disease is characterized by watery diarrhoea, vomiting, and leg cramps. Rapid loss of body fluids leads to dehydration and shock, which without treatment can result in death in a matter of hours. What did the scientists of the day believe caused cholera?In the early 19th century there were many theories as to the cause of cholera, but two were paramount. One theory was that bad air or, "miasma", was the cause. Sanitation and hygiene were poor in 18th and 19th century Shrewsbury.
The alternative theory was the germ theory. The suggestion being that the disease was transmitted from one person to another via infected water. This was supported by John Snow, a Doctor in West London, who proved that a single contaminated drinking source, The Broad Street Pump, was the source of cholera in that area of London. By taking the handle off the pump he stopped the outbreak.
What did the Authorities do to combat cholera?There was a constant battle with local authorities to do something about Public Health. Unfortunately many of them felt that it was too expensive and that they would leave any direct action until legislation made them act.
The correspondence here shows the Shrewsbury Authorities attitude and the problems encountered by professionals trying to improve the situation.
Other views such as the one below provided what appears to be a scientific response which argued against the cause of a water borne infection.
