Coronavirus: Study Confirms Aggravating Age

The coronavirus is more deadly with a high age of the infected patient, confirms a British study. Published Tuesday in the medical journal The Lancet, it shows a strong correlation between age and death rate. It was conducted by researchers from Imperial College, Queen Mary University in London and the University of Oxford.

The estimate was made after studying several hundred Chinese cases of Covid-19 reported in February 2020. According to its results, the disease is on average much more dreadful for people over 60, with a mortality rate of 6, 4% (among confirmed cases). This rate even climbs to 13.4% among those over 80 years old and drops to 0.32% among those under 60 years of age.

Deaths have affected children as young as one year old in the United States, 13 years old in Great Britain and even that of a 16-year-old girl in France.

The study lowers the overall death rate from the disease: 1.38% of deaths according to it among the confirmed cases. The mortality rates she calculated are indeed significantly lower than those of previous estimates, which placed the average proportion of deaths (still among confirmed cases) at more than 2%. Thus, an extensive analysis published on February 24 by Chinese researchers in the American medical journal Jama estimated the average death rate at 2.3%.

In The Lancet, British researchers also show that the proportion of patients who need to be hospitalized, and who are therefore infected in a serious condition, increases sharply with age. Only 0.04% of infected 10-19 year olds require hospitalization. The percentage rises to 1% for 20-29 year olds, 3.4% for 30-39 year olds and 4.3% for 40-49 year olds. It suddenly doubles for 50-59% (8.2%) before flying away: 11.8% hospitalization for 60-69 year olds, 16.6% for 70-79 year olds. It reaches 18.4% in people aged 80 and over.
