People hospitalized with the new coronavirus are as likely to die as those hospitalized with the Ebola virus, according to new research in the UK.
It is the largest study in Europe looking at covid-19 cases, including data from 16,749 patients admitted to the UK. However, the study, published on the medRxiv platform, has not yet gone through the process of peer review, or peer review, when other experts anonymously review the authors’ work before publication.
According to the survey, at least a third of hospitalized patients with covid-19 die. Of the cases analyzed:
The disease has a mild manifestation for most people and can be treated at home, but scientists point out that it is important to emphasize how dangerous the infection can be.
Being obese, old age and being a man are factors that greatly increase the risk of death, according to data from 166 British hospitals.
“Some people insist on believing that covid-19 is no worse than a serious flu. They are seriously wrong,” says Calum Semple, the study’s principal investigator and professor of medicine at the University of Liverpool.
“The crude death rate for people hospitalized with severe covid-19 cases is 35% to 40%, which is similar to that for people hospitalized with Ebola.”
“People need to hear this and put it on their heads … it is an incredibly dangerous disease.”
However, in general, the death rate from the new coronavirus is believed to be less than 1%, as many people have mild manifestations of the disease.
High mortality rates outside ICUs

The study also showed that 31% of patients treated in normal beds died, increasing to 45% in intensive care units (ICUs), where the most drastic interventions are performed, such as the use of mechanical ventilation.
But the research team noted that the apparently high mortality rate in normal beds was not due to a lack of beds in the ICU. Instead, they argue that it may be a right decision not to put patients in intensive care.
Dr. Annemarie Docherty, Honorary UCI Consultant at the University of Edinburgh, says: “If there is little or no chance of recovery, I think we are not doing these people any favors by placing them in an Intensive Care Unit.”
“I think this is a very appropriate and mature discussion that we are having right now in UK hospitals.”
The study confirmed something widely observed in other countries: covid-19 is more deadly in older age groups.
It also showed that the difference between men and women increases with age. Semple says: “In all age groups, more men than women are affected, and the gap increases as we age.”
The explanation for obesity as a risk factor is not clear, but possibly implies the fact that it is associated with other health problems that make the body more vulnerable. Adipose tissue can also release chemicals that increase inflammation in the body; More evident inflammatory processes have been observed in the most severe cases of covid-19.
