基本的健康干預(yù)能大大降低幼兒鐮狀細(xì)胞性貧血的死亡率。這種疾病會導(dǎo)致身體產(chǎn)生鐮刀或者碟狀的血紅細(xì)胞，致使氧氣很難從肺部(36) 傳送出去。(37)尤其是在撒哈拉以南的非洲地區(qū)，遺傳到這種疾病的新生兒數(shù)量正在增加。
美國科學(xué)公共圖書館醫(yī)學(xué)雜志上的一項新的研究表明：到2050年，每年有超過40萬嬰兒生來就有鐮狀細(xì)胞性貧血。杜魯門醫(yī)學(xué)中心的護(hù)士就曾經(jīng)在2007年三月七日在堪薩斯市給雪莉.韋伯(38) 注射緩解其疼痛。疼痛管理對于(39) 罹患鐮狀細(xì)胞性貧血的病人護(hù)理方面至關(guān)重要。每年有10萬新增病例。其中大部分孩子都來自阿爾及利亞、剛果民主共和國和印度。這三個國家(40) 占了2010年患病新生兒的75%。肯尼亞牛津大學(xué)的弗雷德里克•皮爾博士主導(dǎo)進(jìn)行了這項研究。
他說， “這是一種遺傳混亂現(xiàn)象。如果你從父母身上(41) 繼承了一組基因，你不會有任何的癥狀，只被稱為(42) 攜帶者異形接合體人。如果你集成了兩組基因，那么你就是鐮狀細(xì)胞性貧血患者，那在沒有治療(44) 條件的國家 就是很(43) 嚴(yán)重和致命的疾病。”
開始，這種病只是在瘧疾盛行的地方，但因為人口(45) 流動，現(xiàn)在也在世界其它地方普遍起來。所以，這種疾病顯而易見已經(jīng)是世界的負(fù)擔(dān)并且有增長的趨勢。
