In ensuring their access, States must assess and address the particular plight and vulnerabilities of such children. They should, in particular, take into account the fact that unaccompanied children have undergone separation from family members and have also, to varying degrees, experienced loss, trauma, disruption and violence. Many such children, in particular those who are refugees, have further experienced pervasive violence and the stress associated with a country afflicted by war. This may have created deep-rooted feelings of helplessness and undermined a child's trust in others. Moreover, girls are particularly susceptible to marginalization, poverty and suffering during armed conflict, and many may have experienced gender-based violence in the context of armed conflict. The profound trauma experienced by many affected children calls for special sensitivity and attention in their care and rehabilitation.
