Sepsis happens when the body’s immune system goes into overdrive in response to an infection. It is often referred to as septicaemia or blood poisoning.

Everybody is potentially at risk of developing sepsis from minor infections, such as a bacterial throat infection. However, people with CGD and other causes of a weakened immune system (e.g. no spleen or immune suppressant treatment) are more at risk.

If picked up early it can be relatively easy to treat but if treatment is delayed it can progress to septic shock.
