(CNN) “Sometimes I ask myself, why me? Why did this have to happen again?” says 31-year-old Andile from the Khayelitsha township in Cape Town, South Africa. “But the problem is I could have got it anywhere, on the bus, in a taxi, in my work. It’s everywhere.”

Andile has extensively drug-resistant tuberculosis (XDR-TB), a form of the airborne disease that is resistant to the four main groups of drugs used to treat it, meaning treatment can take years and requires alternative drugs that have more side effects.

He’s had tuberculosis for more than two years but it’s not the first time he’s been infected.
