JOHANNESBURG - The lack of proper surveillance of water systems is putting lives at risk, according to Professor Tulio de Oliveira, director of the Centre for Epidemic Response and Innovation.
De Oliveira says South Africa needs stronger water monitoring systems to improve water quality testing and identify pathogens that may be spreading through water sources.
His warning follows reports of more than 800 residents in Bronkhorstspruit suffering from gastrointestinal illnesses, raising concerns about the safety of the area's water supply.

Speaking about the growing problem, De Oliveira said severe gastrointestinal illnesses had affected many people in recent months, including members of his own household.
Those affected experienced symptoms such as vomiting and diarrhoea. He added that, in many cases, health professionals struggle to identify the pathogens responsible for the illnesses.
De Oliveira warned that the problem appears to be becoming more common in South Africa, highlighting the urgent need for improved surveillance and testing.
He said authorities needed to take a step back and strengthen systems that could monitor water quality while also identifying the pathogens being transmitted through contaminated water.
Better surveillance, he believes, is essential to understanding the risks facing communities and preventing further illness.
