Aster Amanuel Desalegn lives in Debre Markos, 190 miles from the Ethiopian capital of Addis Ababa. She is a 70-year-old mother of four and grandmother of two. Her granddaughters, Emuye, 6, and Blen, 8, live with her.
On a trip back from visiting family in Addis Ababa 20 years ago, Desalegn fell ill and went to the nearest health center for help. Doctors said her blood sugar level was critically high and she needed to start treatment right away. For the past 12 years, Desalegn has been taking insulin.
