COVID Far More Lethal Than Flu, Data Shows
By Robert Preidt
FRIDAY, Dec. 18, 2020 (HealthDay Information) — COVID-19 is way extra dangerous and lethal than the seasonal flu, new research verify.
Researchers analyzed U.S. Division of Veterans Affairs knowledge on greater than 3,600 sufferers hospitalized with COVID-19 between Feb. 1 and June 17 of this yr, and greater than 12,600 hospitalized with the flu between Jan. 1, 2017 and Dec. 31, 2019. The common age of sufferers in each teams was 69.
The loss of life charge amongst COVID-19 sufferers was 18.5%, whereas it was 5.3% for these with the flu. These with COVID had been practically 5 occasions extra prone to die than flu sufferers, in response to the examine printed on-line Dec. 15 within the BMJ.
COVID-19 sufferers with the very best danger of loss of life included these aged 75 and older who additionally had continual kidney disease or dementia, and Blacks who had been obese, or who had diabetes or kidney illness.
The examine additionally discovered that COVID-19 sufferers had been 4 occasions extra prone to require respiration machines, practically 2.5 occasions extra prone to be admitted to intensive care, and stayed within the hospital a mean of three days longer than flu sufferers.
A separate examine from France, printed on-line Dec. 17 in The Lancet Respiratory Medication journal, arrived at comparable conclusions: Almost twice as many individuals had been admitted to the hospital for COVID-19 on the top of the pandemic than had been for influenza on the peak of the 2018/2019 flu season. And the loss of life charge was nearly thrice greater.
The French group, led by Dr. Pascale Tubert-Bitter, analysis director at L’Institut Nationwide de la Santé et de la Recherche Médicale (Inserm), and Catherine Quantin, from the College Hospital of Dijon and Inserm, in contrast knowledge from COVID-19 sufferers admitted to the hospital over a two-month interval in spring 2020 with influenza sufferers admitted over a three-month interval through the seasonal flu outbreak of 2018/2019.
“The discovering that the COVID-19 loss of life charge was thrice greater than for seasonal influenza is especially putting when reminded that the 2018/2019 flu season had been the worst up to now 5 years in France by way of variety of deaths,” Quantin famous in a Lancet information launch.
Tubert-Bitter added, “Taken collectively, our findings clearly point out that COVID-19 is way more critical than seasonal influenza. At a time when no remedy has been proven to be efficient at stopping extreme illness in COVID-19 sufferers, this examine highlights the significance of all measures of bodily prevention and underlines the significance of efficient vaccines.”
U.S. researchers stated an enormous shock of their examine was that COVID-19 sufferers had the next danger of creating diabetes, with 9 extra circumstances per 100 than flu sufferers.
“These sufferers did not have diabetes till they acquired COVID-19,” stated examine senior writer Dr. Ziyad Al-Aly, an assistant professor of drugs at Washington College in St. Louis. “Then their blood sugar spiked, and so they wanted big doses of insulin. Is the diabetes reversible, or will it require long-term administration? Will or not it’s sort 1 or type 2 diabetes? We simply do not know as a result of COVID-19 barely existed a yr in the past.”
One other discovering was that COVID-19 sufferers had the next danger of acute kidney injury and extreme sepsis shock. For each issues, there have been a mean of 6extra circumstances per 100 COVID-19 sufferers than amongst flu sufferers.

“Many high-profile, public comparisons between COVID-19 and the flu have been made; nevertheless, these comparisons largely had been drawn utilizing disparate knowledge and statistical strategies which have resulted in quite a lot of conjecture. Our analysis represents an apples-to-apples comparability between the 2 ailments,” Al-Aly stated in a college information launch.
“A deeper understanding of the well being dangers of COVID-19 helps to anticipate demand for well being care companies and to venture mortality with larger accuracy,” he added.
“We all know so little about COVID-19 due to its newness,” Al-Aly famous. “I am undecided why Black sufferers undergo and die extra. My hunch is that the trigger pertains to racial disparities in well being care, however there might be different components that we do not but know.”
