The number of swine flu cases reported in South Africa has gone up to 47, the National Institute for Communicable Diseases (NICD) said on Wednesday.
The increase, from 30 on Monday, was not a cause for panic as all those identified and tested only showed mild symptoms of the influenza A H1N1, commonly known as swine flu, deputy director Dr Lucille Blumberg said.
"Most of the cases are travellers arriving in the country and those who attended the sporting event at the University of Johannesburg."
Emphasising that the rise in the number of swine flu cases did not indicate any danger to the South African public, Blumberg said NICD would only look at the first 100 cases and concentrate on those with severe illnesses if there were any at that time.
Figures released by the World Health Organisation at the end of June indicated that swine flu had infected 59 814 people in 113 countries across the globe and killed 263 people.
