Can i catch sepsis from a family member who has it?

Unlikely to happen: Sepsis or blood poisoning, occurs when a germ gains access to the blood stream and causes dramatic vascular changes in the body. Meningococcus is one germ known to cause sepsis that is contagious. However, normal respiratory (mask) and hand washing measures can prevent spread of this germ. Most other germs involved in sepsis are not very contagious.

Not really: Sepsis is a response to infection, involving fever, elevated white blood cell count, low blood pressure and other signs of impaired organ function. It is mostly caused by infections that are not transmitted person to person.
