Excess mortality: the gold standard in measuring the impact of COVID-19 worldwide?

Our new paper published in the Journal of the Royal Society of Medicine discusses excess mortality during the Covid-19 pandemic. The scale of the COVID-19 pandemic has forced policy-makers to operate with limited evidence for the relative success of different control measures.  Excess mortality is one key outcome measure. The highest excess mortality per million population is seen in Spain, followed by England and Wales. The majority of these excess deaths are caused by COVID-19, but a significant proportion are not directly related to COVID-19. In measuring the impact of COVID-19, mortality is however only one of many important outcomes. Even in ‘mild’ cases not requiring hospitalisation, symptoms can be long-lasting, and heart and lung complications are common, affecting quality of life and ability to work. Beyond the effects on health, the pandemic has disrupted all aspects of society – many countries have experienced record economic recessions, while school closures affect children’s educational attainment.
