عودة الحمى الصفراء

سياتل - قبل أن تبدأ أهوال مرض الايبولا الأخير في غرب أفريقيا بالتلاشي من عقولنا، ظهر فيروس زيكا كخطر كبير يهدد الصحة العالمية ، وهو الآن موضوع قلق بالنسبة للباحثين والأطباء في أمريكا الجنوبية وأمريكا الوسطى، ومنطقة البحر الكاريبي . ومع ذلك، فإن عدد القتلى في ارتفاع مستمر بسبب فيروس آخر: الحمى الصفراء.

في جنوب غرب أفريقيا، تواجه أنغولا وباء الحمى الصفراء الخطير  لأول مرة منذ 30 عاما. منذ أن ظهر الفيروس في لواندا، عاصمة أنغولا والمدينة الأكثر اكتظاظا بالسكان في ديسمبر الماضي، أودى هذا الوباء بحياة 293 شخصا وإصابة 2267. وقد انتشر الفيروس الآن في ست محافظات من بين 18 محافظة في البلاد. ونقل المسافرون معهم المرض إلى الصين، وجمهورية الكونغو الديمقراطية، وكينيا.  والآن توجد ناميبيا وزامبيا في حالة تأهب قصوى.

وينتقل فيروس الحمى الصفراء عن طريق بعوض "الزاعجة المصرية" - نفس البعوض الذي نشر فيروس زيكا. وتشمل أعراض الاٍصابة بالفيروس الحمى وآلام في العضلات، والصداع، والغثيان، والتقيؤ، والتعب. وما لا يقل عن نصف الحالات الشديدة غير المعالجة من الحمى الصفراء يموتون في غضون  10 أو 14 يوما.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession.
