The last time England toured New Zealand for a Test series in 2019, spinner Jack Leach ended up fearing for his life after contracting sepsis.
Leach suffers from Crohn's disease, an inflammatory bowel disease that he was first diagnosed with at the age of 14 which requires him to takes immunosuppressant medication.
After the first Test, Leach contracted gastroenteritis which then turned into sepsis and saw him hospitalised. Speaking in 2020, Leach revealed he was so ill he thought he was going to die, stating: "I remember thinking 'don't fall asleep because you might not wake up'. It was that serious."
