Please tell me how long it takes for to cure sepsis?

Depends...: On a couple of things. First, what type of infection - some resolve quickly with treatment, others may take longer? Second, how many organ systems were impacted by the infection - was there breathing failure, kidney failure, confusion, etc? Also, and probably most important - what was the patient's baseline health and age? Young, healthy people can do better, but can still die from sepsis.

It depends: Some may be cured of it while others may not. It depends on the age, and health of the individual. It also depends timely appropriate treatment.
