Does "Existential recuperation" mean "recuperation for existence"?

Celebration
Saverio Bellizzi; Sassari, Italy

The longest and most complex Ebola epidemic ever still persists in west Africa. The pillars of the strategy against Ebola are isolation, treatment of cases, safe burials, contact tracing, health promotion, and psychosocial support. During the Ebola outbreak I worked as an epidemiologist for Médecins Sans Frontières (MSF) monitoring activities in the Ebola treatment centre and tracing origins of patients to help teams in their efforts to prevent further spread of the epidemic. In this picture, staff at MSF's Prince of Wales Ebola treatment centre in Freetown, Sierra Leone, celebrate the successful treatment of a 6-year-old girl. The cured patient is about to leave the outer part of the centre where she will finally be reunited with her family and receive help from the psychosocial support workers to allow her to move on with her life.

The March for Peace in Bogotá, Colombia, was held on the anniversary of the assassination of populist presidential candidate Jorge Eliécer Gaitán in 1948. At the march this year, there was a general call for a new constitutional assembly to address persistent inequalities. I took this photograph of a citizen reading posters on Calle 26, the main route for the march. The posters include such slogans as “a peace as an excuse to perpetuate inequality”, “in rebellion Latin America recuperates its existence”, and “rebellious memory does not allow the domestication of a hegemonic transition”. As health professionals we deal with the wellbeing of patients in the isolated spaces of clinic rooms. But the March for Peace and the posters pictured here stand as a powerful reminder that health is also negotiated in public spaces, at particular historical junctures, and that to engage in the wellbeing of patients is also to engage in some way with the broader politics of collective identity.
