how did john snow decrease deaths from cholera
John Snow John Snow (15 March 1813 â€“ 16 June 1858) was an English physician and a leader in the adoption of anaesthesia and medical hygiene. He is considered one of the fathers of modern epidemiology, in part because of his work in tracing the source of a cholera outbreak in Soho, London, in 1854. His findings inspired fundamental changes in the water and waste systems of London, which led to similar changes in other cities, and a significant improvement in general public health around the world.
1918 flu pandemic In the United States, the disease was first observed in Haskell County, Kansas, in January 1918, prompting local doctor Loring Miner to warn the U.S. Public Health Service's academic journal. On 4 March 1918, company cook Albert Gitchell reported sick at Fort Riley, an American military facility that at the time was training American troops during World War I, making him the first recorded victim of the flu.[37][38] Within days, 522 men at the camp had reported sick.[39] By 11 March 1918, the virus had reached Queens, New York.[40] Failure to take preventive measures in March/April was later criticised.[5]
