مطاردة فِطر قاتل

سنغافورة ــ في السنوات الأخيرة، ازدادت كثافة وسرعة وتيرة التحذيرات من نشوء ما يسمى الجراثيم العملاقة ــ الميكروبات المسببة للأمراض والتي تقاوم العديد من (أو كل) المضادات الحيوية. ويبدو أن كثيرين لا يدركون أن الجراثيم العملاقة أصبحت معنا حقا ــ وهي تقتل الناس بالفِعل. ومن أقوى الأمثلة على هذا ال"كانديدا أوريس" (Candida auris)، وهي عدوى فطرية مقاوِمة لأدوية متعددة بدأت تبرز بوصفها تهديدا صحيا عالميا خطيرا.

عيَّن الباحثون هوية الكانديدا أوريس لأول مرة في اليابان عام 2009، في أذن مريض يشكو من عدوى. (أوريس في اللغة اللاتينية تعني أذُن). ومنذ ذلك الحين، جرى توثيق الكانديدا أوريس باعتبارها سببا لعدوى تصيب الجروح، ومجرى الدم، والأذن، والجهاز التنفسي في بلدان تقع في أربع قارات، بما في ذلك الهند، والكويت، وباكستان، وجنوب أفريقيا، وكوريا الجنوبية، ودول في أميركا الجنوبية.

في الولايات المتحدة، تشير تقارير مراكز السيطرة على الأمراض والوقاية منها إلى أن الفِطر أصاب 13 شخصا في الفترة من مايو/أيار 2013 إلى أغسطس/آب 2016، وقد توفي أربعة من المصابين. وفي حين يظل من غير الواضح ما إذا كانت هذه الوفيات راجعة إلى الإصابة بعدوى الكانديدا أوريس أو ظروف صحية أساسية، فإن الحاجة إلى معالجة هذه الآفة ــ التي أودت بحياة نحو 70% من المصابين بها ــ لا جِدال فيها.

    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.
