Four new swine flu cases have been reported in the Western Cape, the provincial health department said on Wednesday.
Departmental spokesperson Faiza Steyn said these four cases, which the department was notified about on Tuesday night, brought the provincial tally to 12.
"All are travel cases and they come from countries that have high infection rates."
Steyn said the people were in isolation at home as the cases were mild.
Three were adults and one was a teenager.
The teenager had taken part in a squash tournament in Johannesburg where 11 university students contracted the virus.
Another person had recently come back from travelling in Thailand and Singapore, while the other two people had returned from China and Mauritius, respectively.
According to statistics posted on Tuesday night on the National Institute for Communicable Diseases' website, 93 cases of the AH1N1 influenza had been reported in the country.
The bulk of these - 51 cases - were in Gauteng, with the Eastern Cape and Western Cape each reporting 12 cases.
Limpopo remained free of swine flu, according to the latest figures.
NICD deputy director Dr Lucille Blumberg said once South Africa had reported 100 cases, it would follow the directive of the World Health Organisation and begin to focus on serious cases in people who already had underlying health issues.
She said the figure of 100 cases was just an "arbitrary number" designed to ensure that resources were best managed since most cases of the flu were not serious.
"It spreads very quickly, but most of it is mild and resources need to be tailored to manage the important part of the country." - Sapa
