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.
Cold wave of January 1977 The Cold wave of January 1977 produced the only known trace of snow in the greater Miami area of Florida ever reported (though no snow was reported in the city of Miami). It occurred following the passage of a strong cold front, in combination with a high-pressure area situated over the Mississippi River Valley. As a result, cold air spewed across Florida, causing both snow flurries and record low temperatures. Most notably, the weather system brought snow flurries as far south as Homestead on January 19. Although other portions of the state have since experienced snowfall, no snow had ever been reported in south Florida before or since.[citation needed] Damage was most significant to agriculture, as major losses occurred to Citrus fruits and tender vegetables. Statewide, agricultural damage from the cold wave totaled to $350 million (1977 USD), and losses overall totaled to $2 billion (1977 USD). One fatality occurred due to an automobile accident in Central Florida, which was related to the cold wave.
