Thanks for asking! Ok I will try my best to keep this succinct. The rates of TB and HIV infection are the highest anywhere in the world. What does that mean? It means that men come to the mines and get sick - at rates 28 times higher than a declared emergency. Once they are sick, they get sent home. Their homelands often do not have any access to care.
So they are literally coming to the mines, 'fetching' these diseases, and bringing them home to places with no healthcare.
As a result, the rates of TB and HIV in the general population, not just the mines, are greatly impacted. The mining industry is directly responsible for 760,000 incident cases of TB in the general public of the entire southern African region per year - for perspective, South Africa has about ~350,000 incident cases per year in total. As such, aside from HIV, mining is the largest driver of TB in the southern African region.
Though hundreds of thousands of individuals are affected by mining and TB each year, They Go to Die focuses on the lives of four men affected by this process.
