From the Guardian:
South Africans in an impoverished township are profiting from an illegal trade in a precious new currency ‑ saliva.
Tuberculosis sufferers in Khayelitsha, Cape Town, were found to be selling samples of their sputum to healthy people to pass off as their own in a scam to gain medical grants.
An investigation by the West Cape News identified people with TB charging R50-100 (£4.10-£8.20) for saliva samples contained in bottles stolen from health clinics.
The paper said that buyers of the samples were then able to get a card from a clinic indicating they have TB and use this to fraudulently obtain a temporary disability grant of R1,010 per month from the department of social development.
