The purpose of this guide is to offer recommendations for improving the implementation of non‑pharmacological public health measures during the COVID-19 response and compliance with these measures by population groups in situations of vulnerability. This requires determining the main barriers to implementing these measures so that we can identify the groups and territories most affected during the different phases of the pandemic. With this objective in mind––and within the framework of an equity, human rights, and diversity approach––, policies, strategies, and interventions to accompany the implementation and flexibilization of the measures are recommended to ensure that no one is left behind.
