The biggest killer you may not know – BBC News

What is sepsis?Sepsis is triggered by infections, but is actually a problem with our own immune system going into overdrive.It starts with an infection that can come from anywhere – even a contaminated cut or insect bite.Normally, your immune system kicks in to fight the infection and stop it spreading.But if the infection manages to spread quickly round the body, then the immune system will launch a massive immune response to fight it.This can also be a problem as the immune response can have catastrophic effects on the body, leading to septic shock, organ failure and even death.
