سوء تقدير مخاطر الأمراض المعدية

نيويورك – يقف قادة الأعمال والمستثمرون الدوليون عاجزين إلى حدٍ كبيرٍ أمام نوعين من المخاطر: الاقتصاد الكلي والجيو سياسية. ويعني هذا على المدى القريب تحوّل الأنظار إلى الارتفاعات الوشيكة في أسعار فائدة الاحتياطي الفيدرالي الأمريكي والانتخابات المقبلة في كل من فرنسا وألمانيا. وأما على المدى البعيد، فسوف يعني هذا ازدياد الوعي بالمخاطر الهيكلية مثل ارتفاع حجم الديون السيادية، والتحولات الديمغرافية، ونُدرة الموارد الطبيعية. بيد أن هناك خطر ثالث بالغ الضرر يقبع متخفياً عن أنظار غالبية صنّاع القرار: الأمراض المعدية.

وبحسب تصريحات "توم فريدين" المدير السابق للمراكز الأمريكية لمكافحة الأمراض والوقاية منها، فإن العالم يواجه خطراً أكبر لم يشهده من قبل على صعيد المخاطر الصحية العالمية، فالأشخاص أصبحوا يسافرون إلى أماكن بعيدة وبصورة متزايدة، وتنتشر سلاسل الإمدادات في جميع أنحاء العالم، بما في ذلك الإمدادات الخاصة بالمواد الغذائية والأدوية. فيمكن لإحدى الحالات المصابة بمرض السلّ في أسيا أو أفريقيا مثلا والتي خضعت لمستوىً رديء من العلاج أن تتواجد في إحدى المستشفيات الأمريكية في غضون أيام.   

وفي ظل هذه الخلفية، فإن العلماء يساورهم القلق إزاء الارتفاع الأخير في الأمراض الوبائية مثل زيكا والإيبولا وإنفلونزا الطيور، كما يشعر هؤلاء العلماء بالانزعاج إزاء عودة ظهور الأمراض التي تهدد الحياة مثل الإنفلونزا وفيروس نقص المناعة البشرية/الإيدز، والملاريا، والسلّ.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
