From the Introduction: "Since its emergence in January 2020, six months later Covid-19 [coronavirus disease 2019] is still holding large parts of the world in its grip, as countries have closed their borders and restricted movement within them. Although the virus, and measures to stop or contain its spread, have had a devastating impact on millions of people and societies, refugees and migrants face even greater risk. For them, the virus comes on top of difficulties that were already exacerbated by increasingly stringent and often abusive border and migration policies across the world. This briefing takes a look at the consequences of the Covid-19 pandemic for refugees and migrants, and its anticipated influence on the border security and control market. What are the direct effects on migrants and refugees who are already living in vulnerable situations? What does it mean for people crossing international borders, seeking asylum, and transiting the deadly and treacherous migrant routes across regions, continents and seas? And how are they affected by government responses to the outbreak?"
