"This new facility is the first pediatric surgery and intensive care unit in any Malawi hospital. It will have an enormous impact on saving the lives of children.

The hospital will have three new operating rooms, the unit will be able to double the amount of surgeries currently offered to children as well as provide them with care before and after their surgery.
