Peshawar, Pakistan

Naveed Khan is a 25-year-old civil servant. His life was changed forever when he contracted tetanus from a cut and needed a section of his windpipe removed. But while he was in hospital, he caught infections caused by different types of bacteria.

Colistin is one of very few antibiotics that can still treat certain drug-resistant infections. For Naveed, it was the only one that could help him.
