Understanding one health challenges in marginalized urban settings: A patient and public involvement (PPI) approach from the CHIP consortium activities across four global cities

The study underscores the importance of PPI in addressing One Health challenges in urban slums and reveals interconnected human, environmental, and animal health risks. Engaging communities fostered trust and provided locally relevant solutions to complex health issues like AMR. Future interventions should be co-designed with communities to address social determinants like sanitation and healthcare access for sustainable outcomes.
