ZRS contributor, Annie Herndon, argues that once infected with the zombie sickness, your own immune system may act as the final nail in your coffin. She points to septic shock as the likely reason humans die so quickly after a zombie bite.
Sepsis is a little known condition in which the body is fighting a severe infection that has spread via the bloodstream. The immune system goes into overdrive, overwhelming normal processes in the blood, and leading to blood clots and organ failure.
“The zombie bite doesn’t need to be fatal, because your own immune system will react so violently to the invading sickness that you essentially kill yourself.”
Patients that become septic must be quickly seen by medical professionals or risk falling into a state of shock. If left untreated, death can occur within a matter of hours.
Over 200,000 people die of sepsis each year in the United States alone, and the symptoms so closely mirror those seen in depictions of the aftermath of a zombie bite that Herndon’s hypothesis seems at very least a strong contender.
