Sepsis

Sepsis is a potentially life-threatening condition in which the body's dysregulated response to infection injures its own tissues and organs. It can be caused by bacteria, viruses, parasites, or fungi. Common signs include fever, increased heart rate and breathing rate, and confusion. Sepsis requires immediate treatment with intravenous fluids and antimicrobial medications, with intensive care and organ support sometimes needed. Severity and prognosis are affected by age, immune function, pathogen virulence, and pathogen burden.
