Cholera is an infection of the small intestine that causes a large amount of watery diarrhoea. Cholera is a water-borne disease that is spread through the drinking or eating of contaminated food or water. Cholera symptoms are weakened liver, dehydration, skin going a blue-grey colour. These symptoms usually lead to the person dying within the next 48 hours. This disease was a deadly virus back in London in 1854. It was found to be the source of the water was contaminated with sewerage. This was found by Dr. John Snow. The smell of the sewerage was thought to be the cause of cholera. This was when a sewerage pipeline was designed and built by Joseph Bazalgette to resolve the cholera problem. This did not work as cholera returned 3 months after the system was built. It was found that sewerage was still entering the water supply and that the water purification process was not completed properly. This was solved and cholera is now terminated from England.
