Nick: Finally, tonight the , lengths, and heights, one nurse goes to for her patients.

John yang has the story.

John: To reach the isolated eastern Uganda mountain communities that need her help, nurse Agnes nambozo scales a treacherous 1000-foot ladder, too steep for small children, mothers carrying babies, and the sick to climb down.

>> Pregnant mothers, we can when we come, we also assess them, because the journey is long to the health facilities.

HIV patients, there are those who are bedridden and those with tb, they are unable to come and pick the drugs at the health facility.

So, sometimes we will bring the treatment to their homes.

John: Her most essential mission is vaccinating children against polio, measles, tetanus, and pneumonia as Uganda pushes to reduce the high rate of childhood mortality.

>> Before she came, we used to walk down there, up to Zema.

Sometimes we didn't finish even immunization of our children, because the journey is so long.

When she came, she has helped us so much climbing this area, and we are now finishing immunizing our children.

John: The Gates foundation has recognized her work, which doesn't stop for rain.

And now, nambozo's path has gotten tougher.

Usaid cuts have eliminated many jobs at her clinic.

As she and those who remain try to take up the slack, avoiding burnout could be as much of a challenge as getting to the isolated communities that need her help.
