from Section 3 - Infection: General Principles
Published online by Cambridge University Press: 18 June 2025
Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection (Singer et al. 2016). It manifests as a spectrum of disease characterized by a progression from sepsis to septic shock. Though it has been historically characterized as a severe condition resulting from Gram-negative bacteraemia, sepsis may be the final common pathway to death of many life-threatening infections. Causative pathogens include a wide range of bacteria, viruses, fungi and parasites, and epidemic-prone diseases such as meningococcal meningitis, Ebola Virus Disease (EVD) or COVID-19 can sometimes be detected as outbreaks of sepsis.
