Paula is whistling a lively tune, The Celebratory Song, as she rides her bike to work in the morning. As a social health worker, she feels immense pride in the progress she and her team have achieved over the past decade. The melody lifts her spirits, reflecting the sense of community and accomplishment within her workplace. When Paula reaches the chorus, she starts singing aloud, celebrating the significant health milestones they have reached together. Her voice resonates with joy as she recalls the reduction in non-communicable diseases and improved air quality, all thanks to the dedicated efforts of health workers and their collaborators locally and globally.
