Health officials have reassured South Africans that swine flu has not been reported inside our borders and that the health department are ready for any eventuality.
This follows weekend reports of swine flu in Mexico that has killed at least 103 people.
In the US at least 11 people have been infected.
Gauteng department of health spokesperson JP Louw said yesterday that precautionary measures were being taken.
"Airport officials have been briefed on what to do if they see symptoms. We are ready for anything," Louw said.
Medical adviser to the department Dr Chika Asomugha said the flu was new to the medical profession.
"It's a new flu with characteristics of bird flu, swine flu and human flu," he said.
He said symptoms were fever, sneezing, coughing, aches and pains, runny nose, diarrhoea and vomiting.
Asomugha said diarrhoea and vomiting were the symptoms that distinguished swine flu from ordinary flu.
"Any flu is treatable but research is still being done to see if swine flu can also be treated," said Asomugha.
People can be infected through kissing or by being in close contact with an infected person.
Asomugha said people could not get swine flu by eating pork.
