The road to Mphamba village is unpaved, unlit, and — for half the year — half underwater. Esther leaves her house at four in the morning so that the vaccine cold chain in her cooler box holds. She arrives at the village clinic, a single-room building under a mango tree, by seven.
Community health workers like Esther are the most cost-effective intervention in global health. One nurse, paid a real salary, supplied with real medicine, can prevent more deaths in a year than a hospital wing. The challenge is not the science. The challenge is paying her, supplying her, and keeping her.
A fund-supported community health network commits to all three. Esther earns a salary that does not disappear when a government budget is restructured. Her cooler box is refilled every Monday. When she finds a child whose vaccinations are incomplete, there is somewhere — a real clinic, a real referral pathway — to send them.
Esther is fifty-three. She has a daughter in nursing school. She would like, she says, to stop walking before she turns sixty. But not, she adds, before the road is paved.
“I have walked this road for eleven years. I have not lost a child to measles on this road. That is the only number that matters to me.”
