COVID-19 Lethality and Senior Citizens

Researchers on Monday announced the most comprehensive estimates to date of elderly people’s elevated risk of serious illness and death from the new coronavirus: Covid-19 kills an estimated 13.4% of patients 80 and older, compared to 1.25% of those in their 50s and 0.3% of those in their 40s.

The sharpest divide came at age 70. Although 4% of patients in their 60s died, more than twice that, or 8.6%, of those in their 70s did, Neil Ferguson of Imperial College London and his colleagues estimated in their paper, published in Lancet Infectious Diseases.
