Access to health care is the most important issue faced by refugees, because they might be at a higher risk for certain diseases.

Health of individuals is closely associated with their quality of life. Quality of life over the whole lifespan is pivotal to overall life satisfaction. It includes physical wellbeing, mental health, education, occupation, income, personal safety, as well as (religious) freedom.
