 Many migrants and forcibly displaced persons in the Middle East and North Africa region are facing a higher number of health risks than the rest of the population. This is due to poor living and working conditions, language and cultural barriers, in accessing healthcare, legal status and stigma. Many are not able to access appropriate health services as they are not fully included in national health systems and policies. To address the challenges that migrants face, IOM and WHO have been working across the region to improve the health of migrants including their mental health. IOM and WHO provide a range of health services to migrants as well as host communities and advocate through evidence-based communications for a truly universal health coverage inclusive of migrants. Migrants contribute positively to societies but they cannot contribute to their full potential unless they are in good health. COVID-19 has shown that our individual health is deeply connected with everyone's health, making sure that everyone has access to adequate health services including fair and equitable access to COVID-19 vaccination is not just the right thing to do, it's the smart thing to do. Societies cannot be healthy without healthy migrant communities. Now more than ever, we must leave no migrant behind.
