Radical changes in our understanding of health and healthcare are reshaping twenty-first-century personhood. In the last few years, there has been a great influx of public policy and biometric technologies targeted at engaging individuals in their own health, increasing personal responsibility, and encouraging people to "self-manage" their own care.

One Blue Child examines the emergence of self-management as a global policy standard, focusing on how healthcare is reshaping our relationships with ourselves and our bodies, our families and our doctors, companies, and the government. Comparing responses to childhood asthma in New Zealand and the Czech Republic, Susanna Trnka traces how ideas about self-management, as well as policies inculcating self-reliance and self-responsibility more broadly, are assumed, reshaped, and ignored altogether by medical professionals, asthma sufferers and parents, environmental activists, and policymakers. By studying nations that share a commitment to the ideals of neoliberalism but approach children's health according to very different cultural, political, and economic priorities, Trnka illuminates how responsibility is reformulated with sometimes surprising results.
