In South Africa, thousands of people die from Tuberculosis (TB) every year. It is one of the country's biggest killers – especially as it grows more and  more resistant to drugs.

The deadliest variety is XDR – TB, extensively drug-resistant TB.

Zelda Hansen is just one of the XDR patients at the Jose Pearson Hospital in Port Elizabeth.

"I feel like I'm in prison. I am found guilty for something I can't explain," she says.
