Sweden's strategy to contain the COVID-19 pandemic stands out internationally as more liberal in terms of not ordering a complete lockdown of society. Sweden kept its primary schools, daycare centers and industries largely open. The government financially supported furloughed workers and increased its support to regional and local governments delivering healthcare and elderly care. However, the death toll in Sweden which passed 4000 by late May 2020 stands in stark contrast to those of other, comparable countries, raising questions about the design of the strategy, and its appropriateness. The paper argues that key assumptions sustaining the strategy, for instance that symptom-free people do not carry, and cannot transmit the Coronavirus, or that local and regional government staff had the necessary training and equipment to tackle the pandemic, along with problems associated with coordinating a decentralized healthcare system, may explain the poor performance of the Swedish containment strategy.
