Sepsis is a medical emergency. Time matters. Sepsis is the body's extreme response to an infection. Sepsis can rapidly cause tissue damage, organ failure and death without timely treatment.
Sepsis happens when an existing infection in your skin, lungs, urinary tract, gut or somewhere else spreads and triggers a chain reaction through your body. Sepsis is most commonly caused by Staphylococcus aureus (staph), Escherichia coli (E. coli), and some types of Streptococcus.
