Geneva: The World Health Organization (WHO) said on Thursday that 14.9 million people were killed either by COVID-19 directly or due to the pandemic’s impact on health systems and society, with the global health agency estimating that India had 4.7 million fatalities. In New Delhi, India strongly objected to the use of mathematical models by the WHO for projecting excess mortality estimates linked to the coronavirus pandemic in view of the availability of authentic data, saying validity and robustness of the models used and methodology of data collection are questionable.
New estimates from the WHO show that the full death toll associated directly or indirectly with the COVID-19 pandemic, described as ‘excess mortality’, between January 1, 2020 and December 31, 2021 was approximately 14.9 million, range 13.3 million to 16.6 million. ‘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’, said Dr Tedros Adhanom Ghebreyesus, WHO Director-General.
WHO is committed to working with all countries to strengthen their health information systems to generate better data for better decisions and better outcomes, he said. Excess mortality includes deaths associated with COVID-19 directly (due to the disease) or indirectly (due to the pandemic’s impact on health systems and society). Deaths linked indirectly to COVID-19 are attributable to other health conditions for which people were unable to access prevention and treatment because health systems were overburdened by the pandemic. The estimated number of excess deaths can be influenced also by deaths averted during the pandemic due to lower risks of certain events, like motor-vehicle accidents or occupational injuries.
For India, the cumulative excess deaths associated with COVID-19 pandemic (mean) estimated by the WHO is 4,740,894. In a technical note for India, WHO said the ‘estimates may not be regarded as the national statistics officially produced by India due to differences arising from the data and methods used by WHO’. It noted that the information from the Civil Registration System (CRS) in India for 2020 was made publicly available by the Registrar General of India (RGI) on May 3, 2022 in a report. The newly published information in the report is being carefully examined and will be taken into consideration in revisions of the estimates.
According to a PTI report, quoting sources in New Delhi, India is likely to raise the issue at the World Health Assembly and other required multilateral forums. India has been consistently objecting to the methodology adopted by the WHO to project excess mortality estimates based on mathematical models, the Union Health Ministry said in a statement. ‘Despite India’s objection to the process, methodology and outcome of this modelling exercise, WHO has released the excess mortality estimates without adequately addressing India’s concerns’, the statement said. India had also informed the WHO that in view of the availability of authentic data published through CRS by the RGI, mathematical models should not be used for projecting excess mortality numbers for India.
The Indian government on Tuesday published the CRS report 2020 based on birth and death reports. In case of registered deaths, the number has gone up from 76.4 lakh in 2019 to 81.2 lakhs in 2020, an increase of 6.2%, the RGI’s report ‘Vital Statistics of India based on the Civil Registration System’ for 2020 said. ‘Now that actual count of excess deaths from all the causes are available, there is no rationale for using modelling-driven estimates based on pure conjectures and assumptions’, NITI Aayog member V K Paul told PTI. He pointed out that compared to the calendar year 2018, in 2019 there was 6.9 lakh excess mortality.
The findings of the CRS study assume significance with India recently questioning the WHO’s methodology to estimate Covid mortalities in the country, saying using such a mathematical modelling cannot be applied to estimate the death figures for such a vast nation of geographical size and population. Covid deaths were 1.49 lakh in 2020, according to official data based on a robust surveillance system set up for Covid, he said.
WHO said that most of the excess deaths (84%) are concentrated in South-East Asia, Europe, and the Americas. Some 68% of excess deaths are concentrated in just 10 countries globally. Middle-income countries account for 81% of the 14.9 million excess deaths (53% in lower-middle-income countries and 28% in upper-middle-income countries) over the 24-month period, with high-income and low-income countries each accounting for 15 per cent and 4 per cent, respectively. The estimates for a 24-month period (2020 and 2021) include a breakdown of excess mortality by age and sex. They confirm that the global death toll was higher for men than for women (57% male, 43% female) and higher among older adults.
The absolute count of the excess deaths is affected by the population size. The number of excess deaths per 100,000 gives a more objective picture of the pandemic than reported COVID-19 mortality data. ‘Measurement of excess mortality is an essential component to understand the impact of the pandemic. Shifts in mortality trends provide decision-makers information to guide policies to reduce mortality and effectively prevent future crises. Because of limited investments in data systems in many countries, the true extent of excess mortality often remains hidden’, said Dr Samira Asma, Assistant Director-General for Data, Analytics and Delivery at WHO.
