Informations

The third cholera pandemic (1846–1860) was the third major outbreak of cholera originating in India in the nineteenth century that reached far beyond its borders, which researchers at UCLA believe may have started as early as 1837 and lasted until 1863. In Russia, more than one million people died of cholera. In 1853–54, the epidemic in London claimed over 10,000 lives, and there were 23,000 deaths for all of Great Britain. This pandemic was considered to have the highest fatalities of the 19th-century epidemics.It had high fatalities among populations in Asia, Europe, Africa and North America. In 1854, which was considered the worst year, 23,000 people died in Great Britain. That year, the British physician John Snow, who was working in a poor area of London, identified contaminated water as the means of transmission of the disease. After the 1854 Broad Street cholera outbreak he had mapped the cases of cholera in the Soho area in London, and noted a cluster of cases near a water pump in one neighborhood. To test his theory, he convinced officials to remove the pump handle, and the number of cholera cases in the area immediately declined. His breakthrough helped eventually bring the epidemic under control. Snow was a founding member of the Epidemiological Society of London, formed in response to a cholera outbreak in 1849, and he is considered one of the fathers of epidemiology.

1931 China Flood

Deaths 4000000

Informations

The 1931 China floods, or the 1931 Yangtze–Huai River floods, occurred from June to August 1931 in China, hitting major cities such as Wuhan, Nanjing and beyond, which eventually culminated into a dike breach along Lake Gaoyou on 25 August 1931. Fatality estimates vary widely. A field survey by the University of Nanking led by John Lossing Buck immediately after the flood found '150,000 people had drowned, and that this number represented less than a quarter of all fatalities during the first 100 days of the flood.' The official report found 140,000 drowned and claims that '2 million people died during the flood, having drowned or died from lack of food'. A cholera epidemic in the subsequent year, from May 1932, was officially reported to have 31,974 deaths and 100,666 cases. A popular high-end estimate of 3.7 to 4.0 million fatalities 'enjoys great currency online, helping the 1931 flood to secure its position on sensationalist lists of the world’s deadliest disasters.'
