Caccia al fungo killer

SINGAPORE – Negli ultimi anni si è intensificato l’allarme sull’aumento dei cosiddetti superbug, i microrganismi patogeni che resistono a molti, se non a tutti gli antibiotici. Quello che molte persone sembrano ignorare è che questi super-batteri sono già presenti tra noi, e stanno già mietendo delle vittime. Un esempio fra tutti è la Candida auris, un’infezione fungina multiresistente che sta diventando una seria minaccia per la salute globale.     

Il fungo C.auris venne isolato per la prima volta in Giappone nel 2009, nell’orecchio di un paziente che presentava un’infezione (Auris in latino significa orecchio). Da allora, è stato identificato come la causa di infezioni di ferite, del sangue, dell’orecchio e dell’apparato respiratorio in paesi sparsi in quattro continenti, tra cui India, Kuwait, Pakistan, Sudafrica, Corea del Sud, e in Sudamerica.     

Negli Stati Uniti, i Centri per il controllo e la prevenzione delle malattie segnalano che tra il mese di maggio 2013 e quello di agosto 2016 l’infezione ha colpito tredici persone, di cui quattro sono decedute. Sebbene resti da chiarire se tali decessi siano direttamente collegabili al fungo o ad altre condizioni preesistenti, è fuor di dubbio che questa piaga, che ha causato la morte addirittura nel 70% dei casi, va sconfitta.

    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.
