A study on the Covid-19 pandemic has found that this pandemic could cause a short-term decline in life expectancy in the severely affected areas of the world, unless the spread of the disease is contained.
The study has been published in the journal PLOS ONE. The research examined the impact of Covid-19- related deaths on life expectancy for four broad world regions across multiple rates of infection and age groups.
The researcher Guillaume Marois, from the International Institute for Applied Systems Analysis (IIASA) in Austria, who led the study, observed:
“Our study provides the first assessment of the potential impact of COVID-19 on period life expectancies according to a range of scenarios of prevalence rates over a one-year period.”
Period life expectancy is a measure of the number of years that an average person may expect to live. Prevalence is the proportion of a particular population found to be affected by a disease at a specific time.
The researchers observed that improved healthcare, socio-economic conditions and education are among the key factors influencing our health and how long we live. Life expectancy has been used as a measure of human development across regions and countries.
