|  Essay on Disease in 19th-Century Europe |
|
| Disease in 19th-Century Europe Research Paper, Custom Essays and Term Papers Writing on Health. The foremost explanation of falling death rates lies in the history of contagious disease. One study has suggested that diseases explain 94 percent of all European deaths in the year 1850. The dominion of disease included wars; typhus killed more of Napoleon's soldiers than Wellington's army or the Russian army did. That pattern remained true across the century: Typhus, typhoid, cholera, and smallpox killed more soldiers than enemy fire did. As late as the Boer War (1899-1902), the British army lost 6,425 soldiers in combat and 11,327 soldiers to disease. Contagious diseases killed more people than heart attacks or cancer did, because fewer people lived long enough to experience degenerative problems... |

| Essay on The Effects of Black Death |
|
| The Effects of Black Death Research Paper, Custom Essays and Term Papers Writing on Health. The immediate effect of the Black Death was a precipitous drop in population. From 1348 to 1400, during which time there were several outbreaks of bubonic plague, Europe as a whole (east and west) witnessed a loss of between 22 and 28 million individuals out of a total population of some 73 to 74 million. In short, in a fifty-year period as many as one in three Europeans fell victim to the plague. In Florence the death rate was particularly high; in 1348 alone its population dropped from approximately 120,000 to some 40,000 souls, and losses were even greater in other parts of Tuscany. Italy as a whole probably lost one half its population in the latter half of the fourteenth century. Death became... |

| Essay on The Smallpox Vaccine |
|
| The Smallpox Vaccine Research Paper, Custom Essays and Term Papers Writing on Health. On May 14, 1796, British physician Edward Jenner performed a vital experiment by making two half-inch scratches on the arm of eight-year-old James Phipps and dabbing cowpox pus into them. The pus had come from the cowpox blisters on the hands of milkmaid Sarah Nelmes, who had milked a cow infected with cowpox, as evidenced by lesions on the teats and udder. Phipps developed symptoms of mild cowpox but suffered no long term effects. Six weeks later, Jenner exposed Phipps to smallpox virus in the same manner that he had exposed the boy to cowpox, but Phipps did not become ill. When Jenner exposed Phipps to cowpox, the boy's immune system developed antibodies ready to combat the virus, and these same antibodies... |

| Essay on Making Water Safe to Drink |
|
| Making Water Safe to Drink Research Paper, Custom Essays and Term Papers Writing on Health. Waterborne infectious diseases kill millions of people every year, especially children. Boiling water takes a large amount of energy. Chemicals are expensive, must be regulated carefully, and have side effects. Around 1946, researchers at General Electric found that ultraviolet (UV) radiation from their lamps would kill all of the most harmful bacteria commonly found in water. In fact, UV at 254 nanometers fuses adjacent base pairs in the DNA of bacteria and viruses, rendering the DNA useless to the organism, disabling its ability to generate enzymes for its survival and to multiply and cause disease. Since the bacteria die soon after exposure and cannot reproduce, they pose no threat even if ingested... |

| Essay on The Black Death: Plague in Medieval England |
|
| The Black Death: Plague in Medieval England Research Paper, Custom Essays and Term Papers Writing on Health. A few single events in English history have been both sudden and enormously important. English history without the battle of Hastings and the consequent imposition of a new Norman aristocracy, or without the battle of Saratoga, and the consequent loss of the American colonies, would be unimaginably different. The Black Death of 1349 is a turning point of a different but equally decisive kind. It initiated a long period in which the basic material forces working on society were different from what they had been in the central Middle Ages, and this change had profound effects on almost every aspect of history in the century after. The first plague of 1349 was unmatched in its ferocity... |
