Since 2018, MSF has had a project in the northern Brazilian state of Roraima, aimed at helping the fragile local health system cope with the arrival of thousands of Venezuelan migrants.
As the project developed, it absorbed many workers who are themselves migrants who had crossed the border looking for a better life and are now assisting their own fellow citizens.
And these humanitarian workers also face their own challenges of dealing with their hope of returning to their home country while struggling to integrate into Brazilian society.
