Study begins to reveal clues to the cause and progression of sepsis
...ple components may yield better results. No one really knows why some people develop sepsis following an infection, said Scott Somers, Ph.D., who oversees sepsis grants at the National Institute of General Medical Sciences, which partially funded the work.
