Will Blood infection weaken my baby in any way in the future, and will there be any long-term ill effects caused by it?

In serious infections or infections that involve the spinal fluid or the brain, there can be long-term effects, such as movement abnormalities, mental retardation, cerebral palsy, or hearing loss. There may be some continuing lung abnormalities due to the use of a breathing machine. Occasionally, the blood infection also infects a joint or bone. This could result in an injury to that joint or a limitation of the growth of the bone.
