The COVID-19 pandemic in Singapore was a part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The first case in Singapore was confirmed on 23 January 2020. Early cases were primarily imported until local transmission began to develop in February and March. In late March and April, COVID-19 clusters were detected at multiple migrant worker dormitories, which soon contributed to an overwhelming proportion of new cases in the country.

The Mass Rapid Transit system, locally known by the initialism MRT, is a rapid transit system in Singapore and the island country's principal mode of railway transportation. The system commenced operations in November 1987 after two decades of planning with an initial 6 km (3.7 mi) stretch consisting of five stations. The network has since grown to span the length and breadth of the country's main island – with the exception of the forested core and the rural northwestern region – in accordance with Singapore's aim of developing a comprehensive rail network as the backbone of the country's public transportation system, averaging a daily ridership of 3.4 million in 2019.
