Bad blood pressure and cholesterol numbers are ___1___ for future health problems. You won’t definitely have a heart attack, for example, but your risk is higher. Now researchers have developed a similar-style early warning system for the public health of an entire region. They found that an analysis of particular environmental conditions helps ___2___ the deadly disease cholera. The work is in the American Journal of Tropical Medicine and Hygiene. [Citation to come]
The scientists did a kind of retrospective clinical study, in which they analyzed years of both disease and environmental data from the Zanzibar archipelago, and they discovered that in areas already at-risk a one-degree Celsius increase in temperature over the average monthly minimum ___3___ a doubling of the cholera cases within the next four months. A 200-millimeter increase in the monthly rainfall total also ___4___ a big rise in cholera cases within two months.
Cholera bacteria thrive in warm water where sanitation is poor. So the hotter, wetter conditions are just what the doctor did not ___5___. The researchers hope that monitoring the environment can help communities prepare better for cholera outbreaks.

血壓、膽固醇指數(shù)等不正常，那你將來的健康就可能出現(xiàn)問題了。就拿心臟病來說，不說100％，但你的得病幾率會比常人高很多。對此，研究人員研發(fā)出一種某區(qū)域內(nèi)公共衛(wèi)生的類預(yù)警系統(tǒng)。他們發(fā)現(xiàn)對某環(huán)境條件的分析能夠輔助估計致命疾病霍亂的暴發(fā)率。該研究結(jié)果刊登在《美國熱帶醫(yī)學(xué)與衛(wèi)生雜志》上。
科學(xué)家們進(jìn)行了某種回顧性臨床研究，在此過程中，分析了多年內(nèi)桑給巴爾群島上的疾病數(shù)據(jù)和環(huán)境數(shù)據(jù)。經(jīng)研究發(fā)現(xiàn)，已存在疾病發(fā)生危險的區(qū)域，某月最低平均氣溫每上升1攝氏度，接下來的四個月中霍亂病例數(shù)量就會翻倍。月降水量增加200毫米，接下來的兩個月內(nèi)霍亂病例數(shù)量也會驟增。
霍亂病菌在衛(wèi)生條件差的溫暖水質(zhì)中增殖相當(dāng)迅速。因此醫(yī)生們會讓問診病人盡量避免接觸溫暖潮濕的環(huán)境。研究人員希望環(huán)境檢測能夠幫助人們做好防治霍亂暴發(fā)更完善的準(zhǔn)備。
