A new study suggests that an entirely different infection is responsible for the deaths, which has a higher death rate than covid.
Science Alert writes that the World Health Organization (WHO) has officially declared the end of the coronavirus pandemic, but scientists continue to work to learn more about the virus and its impact on the human body.
In a new study, scientists at Northwestern University in Illinois focused on examining how the coronavirus affects the human body and causes death. The results of the study show that a high percentage of people who need a ventilator due to COVID-19 infection also develop secondary bacterial pneumonia. Scientists have also found that the coronavirus itself is responsible for a higher death rate.

According to Benjamin Singer, a pulmonologist, co-author of the study, he and his colleagues found that although COVID-19 caused patients to be hospitalized, the most likely cause of death was an infection caused by mechanical ventilator use.
The scientists state that the results of the study once again highlight the importance of prevention, investigation and aggressive treatment of secondary bacterial pneumonia in critically ill patients with severe pneumonia, including post-coronavirus.
During the study, the team reviewed the records of nearly 600 patients admitted to the intensive care unit (ICU) at Northwestern Memorial Hospital, Illinois. All patients had severe pneumonia, in some cases accompanied by respiratory failure. At the same time, 190 patients had COVID-19.
To process the data, the researchers used a machine learning approach that groups patients according to their condition and time spent in intensive care.
The results of the study disprove the theory that the organ failure and subsequent cause of death was a post-COVID-19 cytokine storm. There were no signs of multiple organ failure in the patients studied. But scientists have found that coronavirus patients are more likely to develop ventilator-associated pneumonia (VAP). In addition, patients with VAP did not respond to treatment in a significant number of cases in terms of overall mortality.
According to Singer, he and his colleagues found that in most cases, those who manage to recover from secondary pneumonia survive. Patients who could not cope with pneumonia died in most cases.
What’s more, the researchers found that the death rate associated with the coronavirus itself remained relatively low. At the same time, the death rate from secondary bacterial pneumonia was conversely high.
It should be noted that if a patient’s need for a ventilator to treat complications of COVID-19 results in VAP, this does not mean that the COVID-19 infection is less dangerous and does not reduce the number of deaths from COVID-19. .
The scientists also stressed the importance of further research in this area, and caution in assuming cause of death in cases of COVID-19.
