American nurse Marie Elizabeth Bell recently spent nine months in Papua New Guinea, where she worked at the Kunai Health Centre in the southwestern Pacific country’s remote Gulf Province. One patient left a particular impression on her: a woman named Yaniamo, who had experienced nine pregnancies — twice with twins — but had only six living children. Yaniamo was pregnant again, and when her water broke unexpectedly, she began to fear complications. She needed care from Bell’s clinic — a two-day walk from Yaniamo’s home. So she walked.
