We fitted a dynamic transmission model to satellite imagery of the main cemeteries in Mogadishu (Somalia) that showed an unexplained and sustained rise of burials in the period of late February to July 2020. Under the assumption that these excess deaths in Mogadishu were directly attributable to SARS-CoV-2 infection we arrived at median estimates of October-November 2019 for the date of introduction and low R0 estimates (1.3-1.5), stemming from the early and slow rise of excess deaths and their long plateau. Subject to study assumptions, a very early SARS-CoV-2 introduction event may have occurred in Somalia, while showing lower transmissibility in the first epidemic wave than observed in European settings.
