Aisha Muhammed was in the third trimester of her pregnancy when she had the convulsions and high blood pressure of eclampsia, a leading cause of maternal death. Her village's only health clinic had no doctor, and the only medical help was 40 kilometers (25 miles) away in one of the world's most dangerous places.
More women die giving birth in Nigeria than anywhere else in the world, according to the World Health Organization. But Muhammed managed to reach the city of Maiduguri and have a cesarean section the next day, delivering twins in April.
