The pandemic can only be defeated if we work together and use our skills, knowledge and wisdom. With this publication, we make a contribution to this fight in the respect of Human Rights, by giving a voice to people who use drugs and other marginalised and underserved communities, as well as health and social workers delivering services under challenging conditions to bring the COVID-19 outbreak to an end. It gathers valuable experiences and presents responses from which we can draw valuable lessons for our work. The crisis makes our mission all the more urgent: we must stand together, united in a common goal: to save lives and protect people.
