People were terrified of cholera, which was a new and fatal disease in the nineteenth century. However, not all sections of the population welcomed the creation of special cholera hospitals. In Russia and France, people rioted, convinced that the doctors and the government were using the hospitals as a cover to murder the poor. There were also riots in Britain, where people believed that the doctors were dissecting the bodies of patients who died in cholera hospitals.
