The COVID-19 research in Germany is part of the ongoing worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). On 27 January 2020, the first case in Germany was confirmed near Munich, Bavaria. The majority of cases in January and early February originated from the same automobile-parts manufacturer as the first case. On 25 and 26 February, multiple cases related to the Italian outbreak were detected in Baden-Württemberg. A large cluster linked to a carnival event was formed in Heinsberg, North Rhine-Westphalia, with the first death reported on 9 March 2020. New clusters were introduced in other regions via Heinsberg as well as via people arriving from China, Iran and Italy, from where non-Germans could arrive by plane until 17–18 March. German disease and epidemic control is advised by the Robert Koch Institute (RKI) according to a national pandemic plan. The outbreaks were first managed in a containment stage, which attempted to minimise the expansion of clusters. The German government and several health officials stated the country was well-prepared and did not initially implement special measures to stockpile medical supplies or limit public freedom. Since 13 March, the pandemic has been managed in the protection stage as per the RKI plan, with German states mandating school and kindergarten closures, postponing academic semesters and prohibiting visits to nursing homes to protect the elderly. Two days later, borders to Austria, Denmark, France, Luxembourg and Switzerland were closed. By 22 March, curfews were imposed in six German states while other states prohibited physical contact with more than one person from outside one's household.
