As the University of Augsburg writes in a current communication, a study by the Augsburg University Hospital shows that the lung tissue of COVID-19 deceased is irreversibly damaged.
Researchers from Germany and the United States recently reported that COVID-19 damages the lungs differently than influenza.
The extent to which the lungs are damaged in many corona patients has now also been shown by autopsies of COVID-19 deceased.

The majority of people who have contracted the COVID-19 pathogen, the coronavirus SARS-CoV-2, show only mild symptoms.
But for some patients, the disease can also take a severe course and lead to death.
A new study has now shown that severe lung damage is often the cause of the death of the sick.
Lung damage: important information about the cause of death of corona patients
The cause of the damage was the coronavirus, the genetic makeup of which could still be detected in the respiratory tract.
Lung damage from mechanical ventilation was largely excluded as the cause, since more than half of the patients were not artificially ventilated.
The study results were recently published in the renowned journal of the American Medical Association (JAMA).
Massively impaired oxygen intake in the lungs
According to the experts, the massively impaired oxygen intake of the lungs ultimately led to the death of the sick.
However, some of the infected develop pneumonia, which in a small proportion of cases is so severe that artificial ventilation is required.
Despite all intensive medical measures, patients die from this disease.
In most cases, the infection with the SARS-CoV-2 coronavirus occurs as a complication-less illness of the upper respiratory tract, especially the throat.
Thanks to careful information from the relatives, an autopsy rate of almost 90 percent of the deaths was achieved in Augsburg, which allowed the doctors to give an unbiased assessment.
An interdisciplinary team of doctors around the Augsburg pathologist Dr.
Tina Schaller has been leading
April this year 19 post-mortem examinations on patients with COVID-19.
The medical team sees this change as the cause of death because it massively affects the oxygen uptake by the lungs to supply the organs.
According to the information, the lung tissue itself consistently showed unusually severe, sometimes presumably irreversible, damage.
“During the examinations, we were still able to detect the genetic makeup of the virus in the respiratory system of the deceased,” explains Dr.
Schaller, senior senior physician and first author of the study.
