Porque é que a tuberculose persiste?

SÃO FRANCISCO – Muita gente na Europa e na América do Norte fica surpreendida pelo facto de a tuberculose (TB) continuar a ser um dos grandes flagelos da história da humanidade. Uma em cada três pessoas no mundo está infetada com tuberculose latente ou subclínica e os cientistas estimam que 10% delas manifestem a doença, à medida que a idade e outras doenças forem comprometendo o seu sistema imunológico. Em 2015, foram registados mais de dez milhões de novos casos de TB e cerca de dois milhões de pessoas morreram da doença.

Há três razões para a persistência da TB: os líderes políticos não entendem a sociologia que existe por trás do fenómeno, os cientistas não possuem um paradigma eficaz para combatê-la e os ricos e famosos já não morrem de TB.

A TB já afetou, em tempos, todas as classes da sociedade, mas agora atinge as populações mais vulneráveis. Isto torna-a num meme ideal para os artistas e ativistas que se centram na justiça social. A incidência da tuberculose resistente aos fármacos está a aumentar, porque os sistemas de saúde dos países pobres carecem dos recursos para avaliar a TB e para ajudar os pacientes a completarem os seus tratamentos.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    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.
