From the Cape Times:
There has been no increase in reported cases of diarrhoea since rat-tailed maggots were first spotted in a Stellenbosch river at the beginning of the year, Andile Zimba, Cape Town’s acting director of health, said yesterday.
In a presentation to the health portfolio committee, Zimba said the monthly statistics for diarrhoea had shown no increases, and there was no evidence that the maggots were responsible for the diarrhoea cases.
