What happens when a bacterial infection gets worse?

Any severe or untreated bacterial infection can trigger an exaggerated immune response called sepsis. This condition can lead to tissue damage, organ failure, and death. Some signs and symptoms of sepsis include: fever or chills.

What happens if an infection gets worse?
