Come sconfiggere i superbug

LONDRA – Gli attuali antibiotici stanno diventando sempre più inefficaci, non solo nel combattere le comuni malattie come polmonite e le infezioni del tratto urinario, ma anche nel trattare una serie di infezioni, come la tubercolosi e la malaria, che ora rischiano di diventare nuovamente incurabili. I leader del G7 si sono impegnati, in una recente dichiarazione congiunta, ad affrontare la “resistenza antimicrobica” (AMR), ed è tempo che il più inclusivo G20 – e la Cina, in quanto presidente del gruppo per la prima volta – portino la lotta al livello successivo.

Se non si affronterà la farmacoresistenza, ci saranno conseguenze per tutti, a prescindere dalla nazionalità o dal livello di sviluppo del Paese. Entro il 2050 la resistenza ai farmaci antimicrobici mieterà 10 milioni di vittime. Oggi muoiono circa 700.000 persone a causa della farmacoresistenza, con Cina e India che registrano ciascuna circa 1 milione di malati. A questo punto, il costo stimato di 100 mila miliardi di dollari in Pil globale saranno già andati persi.

Nessuna strategia del G7, per quanto ben elaborata, potrà funzionare se non sarà coinvolta l’intera comunità internazionale. Dopo tutto, se le infezioni viaggiano insieme alle persone affette, anche per la resistenza vale lo stesso principio, e ciò significa che l’unica soluzione per la farmacoresistenza è agire all’unisono. È per questo motivo che i membri dell’Organizzazione mondiale della sanità si sono accordati per implementare un “piano d’azione globale sulla resistenza ai farmaci antimicrobici”, e si sono rivolti alle Nazioni Unite affinché convocassero un vertice di alto livello con i leader politici nel 2016.

    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.

    • 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.
