Sepsis, a life-threatening condition arising from the body’s overwhelming response to an infection, claims more lives globally than all cancers and accidents combined. This complex syndrome is often underrecognized and can progress rapidly, leading to organ damage, failure, and death. Its impact is particularly pronounced in vulnerable populations, including the very young, the elderly, and individuals with compromised immune systems. Understanding the underlying mechanisms and improving early detection and treatment strategies for sepsis are critical to addressing this significant public health challenge.
