Migrants can be considered as long‐term travelers, but whereas travelers are free to move and can have easy access to services, migrants are bound by regulations and rules beyond their control, which may limit their access to healthcare. From a public health perspective, they are all mobile populations and contribute to the overall impact of global mobility, such as the circulation of infectious diseases. Migrants represent a very diverse population of various origins and sociocultural backgrounds, which will greatly influence their interaction with medical providers. In this context, it is essential to acquire cultural competence. Healthcare practitioners need to understand how each patient's sociocultural background affects their health beliefs and behavior. They need also to be aware of the epidemiology and clinical manifestations of diseases with which they may not be familiar. More important is the set of core values that should guide their practice: empathy, curiosity, and respect.
