Sepsis Explained: When Infection Sparks a Life‑Threatening Response
Sepsis is a potentially deadly, umbrella term for an overactive, unpredictable immune response to infection that can follow pneumonia or other infections. There isn’t a single test for sepsis; diagnosis relies on symptoms and clinical judgment. Common signs include fever, low blood pressure, a fast heart rate, and confusion, though symptoms vary by infection source, and septic shock can lead to organ failure. Kyle Busch’s death after pneumonia progressed to sepsis underscores the risk. Prompt emergency treatment is crucial, and prevention—through vaccines and proper infection care—can reduce risk.
