Medical experts warn that Hospital Acquired Infection or HAI, will become the leading cause of human death. HAI affects patients admitted to a hospital or other health-care facility, and is caused by disinfectant resistance - which not many people are aware of. According to the World Health Organisation, 53 to 70% of patients who acquire HAI are likely to die.

For more on this, we are now joined on the line by Professor Robert Bragg from the University of the Free State in South Africa.

He spoke on the need to fight disinfectant resistance, a discussion held this week by PMB health and Safety Services at the Gallagher Convention Centre in Johannesburg.
