COVID-19 is no longer classed as a global health emergency by the World Health Organization, but scientists are still working hard to understand more about the virus and its impact – including how the coronavirus affects the body and leads to death.
A new analysis suggests that a high percentage of people who required help from a ventilator due to a COVID-19 infection also developed secondary bacterial pneumonia. This pneumonia was responsible for a higher mortality rate than the COVID-19 infection.
So while COVID-19 may have put these patients in the hospital, it was actually an infection brought on by the use of a mechanical ventilator that was more likely to be the cause of death when this infection didn’t respond to treatment.
“Our study highlights the importance of preventing, looking for, and aggressively treating secondary bacterial pneumonia in critically ill patients with severe pneumonia, including those with COVID-19,” says Benjamin Singer, a pulmonologist at Northwestern University in Illinois.
