The ongoing coronavirus pandemic has had significant impacts on mobility within West Africa. This Snapshot is the second in a series that documents the phenomenon in West Africa through an adapted version of MMC’s regular 4Mi data collection carried out in Niger, Mali, and Burkina Faso. It provides insight into access to healthcare, of the scale of testing for COVID-19, and precautions being taken among people on the move. This snapshot is based on telephone surveys carried out with 1,396 refugees and migrants in Niger (464), Mali (530), and Burkina Faso (402), between 20 April and 20 June 2020.
