New research suggests that the virus responsible for COVID-19 was a more common and deadly cause of sepsis early in the pandemic than previously assumed — accounting for about one in six cases of sepsis from March 2020 to November 2022.
The results, published online in JAMA Network Open, suggest that clinicians should rethink how they treat sepsis while also providing a framework for future surveillance of viral sepsis.
Sepsis is a serious, sometimes fatal overreaction of the immune system to an infection. Doctors and researchers don’t know as much about sepsis that occurs in response to viral infection as they do about sepsis that arises from bacterial infection.
“Most people, including medical professionals, equate sepsis with bacterial infections,” said first author Claire Shappell, HMS instructor in medicine at Brigham and Women’s Hospital. “This is reflected in treatment guidelines and quality measures that require immediate antibiotics for patients with suspected sepsis.”
