Over 28 million more years of life were lost than expected in 2020 due to Covid-19 pandemic, finds a study. The study, published by The BMJ, analysed the effects of Covid-19 pandemic on life expectancy and premature mortality in 2020 in 37 upper-middle and high-income countries.

Rate of excess premature deaths was found to be higher in men than women, said Dr Nazrul Islam from the Nuffield Department of Population Health, University of Oxford.

In 31 of 37 countries, more than 222 million years of life were lost in 2020, which is 28.1 million more than expected (17.3 million in men and 10.8 million in women).

The highest decline in life expectancy (in years) was in Russia (minus 2.33 in men and minus 2.14 in women), the US (minus 2.27 in men and minus 1.61 in women), Bulgaria (minus 1.96 in men and minus 1.37 in women), Lithuania (minus 1.83 in men and minus 1.21 in women), Chile (minus 1.64 in men), and Spain (minus 1.11 in women).

Only Taiwan, New Zealand, Denmark, Iceland, Norway, and South Korea, had comparable or lower than expected years of life lost.

This "underscores the importance of successful viral suppression and elimination policies, including targeted and population based public health policy interventions," the researchers wrote in the study.

The team also compared the observed life expectancy and years of life lost in 2020 with those that would be expected based on historical trends in 2005-19 in 37 upper-middle and high-income countries.

Overall, excess years of life lost to the Covid-19 pandemic in 2020 were more than five times higher (2,510 per 100,000) than those associated with the seasonal influenza epidemic in 2015 (458 per 100,000), Islam said.

It was also relatively low in people younger than 65 years, except in Russia, Bulgaria, Lithuania, and the US where the excess years of life lost was more than 2,000 per 100,000.

"A comprehensive pandemic preparedness aimed at more resilient health systems could be key to tackling the impact of future pandemics. Quantifying the effects of specific policy interventions on the reduction of premature deaths will help inform future policy intervention," the researchers said.

The researchers acknowledge some limitations. For example, they did not include most countries from Asia, Africa, and Latin America due to a lack of data, and were unable to take account of other critically important factors, such as socioeconomic status, regional disparities, and race or ethnicity.

Global caseload

The global coronavirus caseload has topped 248 million, while the deaths have surged to more than 5.02 million and vaccinations soared to over 7.13 billion, according to Johns Hopkins University.

In its latest update on Thursday morning, the University's Center for Systems Science and Engineering (CSSE) revealed that the current global caseload, death toll and the total number of vaccine doses administered stood at 248,044,382, 5,021,217 and 7,133,252,656, respectively.
