Sepsis (when an infection becomes life threatening) is a neglected public health problem affecting as many as cancer, with a higher mortality rate than myocardial infarction and is very expensive. Sepsis is a complex syndrome, akin cancer and should not be classified as a single disease, rather many different depending on 1. the bacteria causing the infection, 2. Organ focus of the infection, and 3. perhaps most importantly, in which inflammatory stage the individual sepsis patient is when searching care. Our group focuses on knowledge, incidence, epidemiology, long-term complications, pathophysiology, biomarkers, diagnostics and new treatments for sepsis. We focus on mapping out the sepsis progression in order to "personalize" sepsis diagnosis and treatment. We also study the special groups of sepsis; such as meningitis, neutropenic and postoperative sepsis. In order to increase public awareness of sepsis we cooperate with the Swedish Sepsis foundation (www.sepsisfonden.se).
