In this connection it may be noted that in total, 20,507,518 years of life have been lost to COVID-19 among the studied 81 countries, due to 1,279,866 deaths from the disease. The average years of life lost per death is 16 years. Feb 18, 2564 BE. This is equivalent to shortening of 0.0026 year of life expectancy loss of the entire world on average. c) Potential Gains in Life Expectancy It is noted that if the measures can be taken to stop the losses in full, the losses can be recovered in full and the life expectancy can be increased to the extent shown. But it is really difficult to achieve this. So, two scenarios are prepared for potential gains in the average expected life years. Scenario A: Elimination of all deaths from specific diseases in people aged 30–70 years Scenario B: Reduction in deaths from specific disease in people aged 30–70 years by a third. Both the scenarios are shown in Table 3.3. The Sustainable Development Goal is set by the United Nations. (The Lancet GlobalHealth) estimated in the Sustainable Development Goal two scenarios of potential gains. The potential gains in life expectancy from the diseases according to World Bank Income Group are shown in Table 3.3.
