Como combater a resistência antimicrobiana

ZURIQUE —Há duas semanas, os líderes do G20 assumiram o compromisso de trabalhar em conjunto para enfrentar uma das ameaças no domínio da segurança mais prementes e desconcertantes do mundo: a resistência antimicrobiana (RAM) —um adversário feroz e em evolução contra o qual as armas terapêuticas convencionais são inúteis.

A ameaça é evidente: as bactérias e outros micróbios estão a tornar-se resistentes aos medicamentos disponíveis a um ritmo mais acelerado do que o do desenvolvimento de novos medicamentos. Todos os anos, os micróbios resistentes a medicamentos são responsáveis pela morte de cerca de 700 mil pessoas em todo o mundo —mais do triplo do número anual de mortes decorrentes de conflitos armados.

Em 2016, um painel especial encomendado pelo governo britânico previu que até 2050, pelo menos mais dez milhões de pessoas morrerão anualmente devido a micróbios resistentes a medicamentos. A RAM representa actualmente um perigo claro e eminente para todas pessoas no planeta. Se não a enfrentarmos directamente, poderemos voltar a um mundo em que é comum as pessoas morrerem de uma simples infecção.

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
