2017年的全球健康希望

香港——回顾2016年,似乎没有什么事情值得人们庆贺。仅就全球卫生领域而言,这一年,似乎是一个无情的悲剧。除冲突地区医院屡遭轰炸外,寨卡病毒也成为一种日益增长的威胁。此外还有抗生素耐药性微生物,或者“超级细菌”的扩散、黄热病持续复苏,以及脊髓灰质炎在尼日利亚重现。此前尼日利亚已经被宣布为无脊髓灰质炎地区。呼吸道多细胞病毒疫苗希望破灭。而且在欧洲,与酒精相关的死亡事件不断增加。

但2016年全球卫生领域某些鼓舞人心的进展就隐藏在这些坏消息之下。

第一个鼓舞人心的进展发生在坦桑尼亚和莫桑比克,此前曾被比利时非政府组织APOPO训练用于检测地雷的非洲巨鼠现在被赋予防治结核病的全新任务。这些大鼠接受全面训练以及各种刺激,学会如何与人类互动,并被教授如何在痰液(即下呼吸道咳出的黏液)样本中发现结核病毒。大鼠发现结核菌的准确率近乎百分之百,虽然它们尚无法分辨正常和耐药菌株。

    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.

    Rage Against the Elites

    • With the advantage of hindsight, four recent books bring to bear diverse perspectives on the West’s current populist moment. 
    • Taken together, they help us to understand what that moment is and how it arrived, while reminding us that history is contingent, not inevitable

    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.
