The United States has been hit particularly hard having 20 percent of the world's infections but only 4 percent of the world population.

A Harvard researcher has added up the number of years that Americans who died from Covid-19 would have lived had they reached a typical life expectancy. In total, the Coronavirus has claimed 2.5 Million years of potential life in the United States. Nearly half of those years were taken from people under the age of 65.

The new analysis, which has not yet been published in a peer-reviewed scientific journal, was released by medRxiv (founded by Cold Spring Harbor Laboratory).

About 80 percent of the Americans who have died from the coronavirus were over 65. Despite making up only one-fifth of the total recorded deaths related to Covid-19, people under 65 accounted for nearly 1.2 million years of potential life that had been lost to the virus. Older people made up the remaining 1.4 million years.

The analysis did not break down potential life-years lost by race and ethnicity. 

The numbers magnify a dimension of the pandemic’s toll that can’t be captured by absolute deaths alone, and underscore the importance of taming the virus to protect everyone, regardless of age.
