If COVID-19 continues to spread, there would be a decrease in the life expectancy of people, especially in regions which have been affected severely by the infection, according to a recent study, published in the journal PLOS.

Life expectancy is the way to measure the number of years that an average person is expected to live. Factors such as healthcare facilities, socioeconomic status and education facilities are factored in while calculating life expectancy.

In order to prove their point, the scientists built a model which resembled the life of individuals, who were monitored every week for almost a year (52 weeks).

In that model, the scientists studied the age-specific prevalence rate of COVID-19 infection and also the probabilities of dying from the infection. The scientists further examined the length of illness of the disease, which is expected to be 2 weeks.

The study was conducted in four different regions based on their life expectancy rates:

1. Very high life expectancy (North America and Europe)
2. High life expectancy (Latin America and the Caribbean)
3. Medium life expectancy (Southeastern Asia)
4. Low life expectancy (Sub-Saharan Africa)

RESULTS of the study:

Life expectancy would suffer even at the regions which present with a mere 2% prevalence of COVID-19 infection.

Regions that presented with 10% prevalence, showed a loss of more than 1 year in their life expectancy rates. Ones with 50% prevalence of infection would show a loss of 3 to 9 years in the regions with high life-expectancy regions, 2 to 7 years in the regions with medium life-expectancy regions, and 1 to 4 years in the regions with low life-expectancy regions.

It was concluded that if the spread of COVID-19 infection and the number of deaths are not contained, the life expectancy would drop significantly, especially in the places where the life expectancy is already low.
