In pictures: Surviving Congo

Idumbo Mokina (centre) says that his sister Ngalia Laini was rushed to the clinic last year after becoming ill with headaches and cramps.

"They kept her overnight," he says. "In the morning, they told us that it was meningitis and that we had to take her to the clinic in Moga, 12 hours' walk from here. So I made a stretcher and organised a group of 17 villagers to carry her.

"But after four hours on the road she died. She was 45 years old."
