問題詳情
45 至 48 題為題組West Nile is a tropical disease that begins in birds, which pass it on to mosquitoes that then go on toinfect human beings with a bite. Most people who contract West Nile do not experience any symptoms atall, but, if they do, symptoms typically develop between 3 to 14 days after a mosquito bite. About 1 in 5persons suffers fever, headaches, and body aches, usually lasting a week or so. A far less lucky 1 in 150experiences high fever, tremors, paralysis, and coma. Some—especially the elderly and those with weakimmune systems—die.That is what made the major outbreaks of West Nile in the U.S. in the summer of 2012 so scary. Thesituation was particularly bad in Dallas, Texas, where the West Nile virus killed 10 people and sickenedmore than 200. The city declared a state of emergency and began aerial spraying of a pesticide to kill themosquitoes, even though residents argued that the pesticide could be more dangerous than the disease.Why was the summer of 2012 so hospitable to the West Nile virus and the mosquitoes that carry it?Blame the weather. An extremely mild winter allowed more mosquitoes than usual to survive, while theunusually high temperatures in that scorching summer further increased their number by speeding up theirlife cycle. The economic crisis may have also played a role: Homeowners who were not able to pay theirbank loans were forced to abandon their properties, sometimes leaving behind swimming pools that madeexcellent mosquito breeding grounds.The severity of tropical diseases is also a matter of whether governments are capable—and willing—to defend their populations against infections. Dallas County was not doing some of the key things to slowthe spread of West Nile, such as testing dead birds and setting mosquito traps to test for the presence of thedisease. Tropical infections are thus as much related to government inaction as they are to climate.

西尼羅河病毒是一種熱帶疾病,從鳥類開始,將其傳遞給蚊子,然後繼續咬傷感染人類。 大多數患有西尼羅河病毒的人根本沒有任何症狀,但是,如果他們這樣做,症狀通常會在蚊蟲叮咬後3至14天內發生。大約五分之一的人患有發燒,頭痛和身體疼痛,通常持續一周左右。不幸的是,150人中有1人遇到高燒,震顫,癱瘓和昏迷。 一些人 - 尤其是老年人和免疫系統較弱的人 - 死亡。這就是2012年夏天美國西尼羅河大爆發如此可怕的原因。 在得克薩斯州達拉斯,情況特別嚴重,西尼羅河病毒造成10人死亡,200多人生病。該市宣布進入緊急狀態並開始空中噴灑殺蟲劑以殺死蚊子,儘管居民認為殺蟲劑可能比疾病更危險。 為什麼2012年夏天對西尼羅河病毒以及攜帶它的蚊子...
