COVID-19 leaves few lives and places untouched. But its impact is harshest for those groups who were already in vulnerable situations before the crisis. This is particularly true for many people on the move, such as migrants in irregular situations, migrant workers with precarious livelihoods, or working in the informal economy, victims of trafficking in persons as well as people fleeing their homes because of persecution, war, violence, human rights violations or disaster, whether within their own countries — internally displaced persons (IDPs) — or across international borders — refugees and asylum-seekers.
