JOHANNESBURG — Thethiwe Mahlangu woke early on a chilly morning and walked through her busy South African township, where minibuses hooted to pick up commuters and smoke from sidewalk breakfast stalls hung in the air.
Her eyes had been troubling her. But instead of going to her nearby health clinic, Mahlangu was headed to the train station for an unusual form of care.
A passenger train known as Phelophepa — or ''good, clean, health" in the Sesotho language — had been transformed into a mobile health facility. It circulates throughout South Africa for much of the year, providing medical attention to the sick, young and old who often struggle to receive the care they need at crowded local clinics.
For the past 30 years — ever since South Africa's break with the former racist system of apartheid — the train has carried doctors, nurses and optometrists on an annual journey that touches even the most rural villages, delivering primary healthcare to about 375,000 people a year.
The free care it delivers is in contrast to South Africa's overstretched public health care system on which about 84% of people rely.
Health care reflects the deep inequality of the country at large. Just 16% of South Africans are covered by health insurance plans that are beyond the financial reach of many in a nation with unemployment of over 32%.
Earlier this year, the government began to address that gap. President Cyril Ramaphosa in May signed into law the National Health Insurance Act, which aims to provide funding so that millions of South Africans without health insurance can receive care from the better-provisioned private sector.
But the law has been divisive. The government has not said how much it will cost and where the money will come from. Economists say the government will have to raise taxes. Critics say the country can't afford it and warn that the system — yet to be implemented — will be open to abuse by corrupt officials and businessmen. They say the government should fix the public healthcare system instead.
