Covid-19 could thus set back this indicator in 2020 to the values observed some time ago,” IIASA researcher Sergei Scherbov, who worked on the study, said. “However, we do not know what is going to happen further. In many countries fatality from Covid is strongly decreasing, probably because the protocol of Covid treatment became better defined.”Life expectancy is calculated based on annual mortality rates. The high number of deaths in Covid, especially in older people could end up skewing that number. While higher incidence of the disease is not directly linked to mortality, overcrowding of health facilities could cause more casualties, the researchers reasoned. That is why higher incidence would have a larger impact.“The impact of Covid-19 on the period life-expectancy would be lower in Southeastern Asia, and even much lower in sub-Saharan Africa,” the study states.“For Southeastern Asia, one year lost in life expectancy corresponds to an infection prevalence of about 15 per cent compared to a prevalence of 25 per cent in sub-Saharan Africa,” it adds. “At 50 per cent infection prevalence, the years of life lost amount to 3.5 years in South Eastern Asia and 2 years in sub-Saharan Africa. In short, loss in life expectancy in sub-Saharan Africa would be half of those in North America and Europe, while years of life lost due to Covid-19 in Southeastern Asia would lie between the other two regions.”According to the study, there will be no impact on life expectancy if the incidence level is low. In regions with high life expectancy (80s), the trend of that number rising would be broken only at a threshold incidence of two per cent, the study states.Also read:&nbsp;&nbsp;Support Our JournalismIndia needs fair, non-hyphenated and questioning journalism, packed with on-ground reporting.
