More men (57%) have died directly or indirectly as a result of COVID than women (43%) worldwide, the WHO data shows.
The World Health Organisation estimates that 15 million people worldwide have now died of coronavirus – or as a result of its impact on health services.
WHO data shows the number of excess COVID mortalities to be somewhere between 13.3 million and 16.6 million people from 1 January 2020 to 31 December 2021. This is more than double the official death toll of around six million.
Excess mortality refers to the number of people who have died of the virus either directly or indirectly by being unable to access health services for other conditions.

The figures were compiled using country-reported data and statistical modelling, the WHO said.
There were 14.9 million excess deaths associated with COVID-19 by the end of 2021, the UN body said on Thursday.
Most excess COVID deaths (86%) happened in Asia, Europe and the Americas, according to the figures.
Middle-income countries accounted for 81% of deaths, with 28% occurring in upper-middle-income countries and 4% in low-income ones.
Some 68% of all excess deaths worldwide happened in just 10 countries.
There was a higher rate for men (57%) than there was for women (43%), with more excess deaths among the elderly than younger generations.
WHO director-general Dr Tedros Adhanom Ghebreyesus commented: “These sobering data not only point to the impact of the pandemic but also to the need for all countries to invest in more resilient health systems that can sustain essential health services during crises, including stronger health information systems.
“WHO is committed to working with all countries to strengthen their health information systems to generate better data for better decisions and better outcomes.”
