The World Health Organisation, WHO, says millions of refugees and migrants in vulnerable situations, face poorer health outcomes than their host communities especially where living and working conditions are sub-standard.
Its Director-General, Doctor Tedros Ghebreyesus, said there were some one billion migrants globally, about one in eight people.
According to him, the experience of migration is a key determinant of health and wellbeing, and refugees and migrants remain among the most vulnerable and neglected members of many societies.
The report is the first to offer a global review of refugee and migrant health, calling for urgent and collective action to ensure they can access health care services that are sensitive to their needs.
