Blood-infections can be severe as well as fatal as it hampers the normal physiology of important organs. Lungs, Gastrointestinal Tract, Gallbladder, Kidney, Heart are common sources of blood-borne infections. Weak or compromised immunity is another reason for infection, especially in case of newborns, kids and older people.
