A recent study found that secondary bacterial pneumonia, rather than the much-discussed “cytokine storm,” is a significant factor in COVID-19-related fatalities.

Almost half of the patients who required mechanical ventilation support were affected by this secondary bacterial infection.

By applying machine learning to analyze medical records, the researchers found that those who recovered from secondary pneumonia were more likely to survive, whereas unresolved cases increased mortality risk.

The study, which challenges the cytokine storm theory, emphasizes the importance of preventing and aggressively treating secondary bacterial pneumonia in critically ill patients.
