Eleven Australians have been tested for Ebola in recent weeks but all have been cleared.

Health authorities have confirmed that Cairns nurse Sue-Ellen Kovack, 57, has been cleared of Ebola by initial tests.

But federal Health Minister Peter Dutton says she’s not the only one who has undergone testing in recent weeks.

“Already we’ve had 11 cases that have presented across the country that have all been negative,” he told reporters in Brisbane.

“We have put in place plans in major tertiary hospitals around the country that if we do have a positive case, we will be able to deal with that case.”

The chief medical officer, chief of the defence force and immigration department secretary have all advised the federal government on how to respond to the growing Ebola crisis around the world.

Initial screening is now able to be done at airports and passengers on planes coming from affected African countries are being given information about the disease.

“That provides a world-class response and is probably ahead of the game where other developed countries are at the moment,” Mr Dutton said.

Ebola screening ramped up

Ebola screening measures are being ramped up at international airports around Australia but the Health Department says the risk to the country remains low.

Travellers arriving in Australia from West African countries are being interviewed and screened for symptoms of Ebola by border staff.

These health checks are required for anyone arriving from the four affected countries of Guinea, Liberia, Sierra Leone and Nigeria, along with arrivals from the Democratic Republic of the Congo.

Banners have now been fixed in international airports to raise awareness of the symptoms of the deadly virus, and pamphlets distributed on some flights.

“The Australian government has put in place additional measures to address the low risk of Ebola to Australia,” a spokeswoman for the Australian Department of Health said on Friday.

All border agencies have been educated by the Department of Health to identify and quarantine any passengers presenting Ebola symptoms in flights or at airports.

The Department said very few people travel to Australia from West Africa, with no direct commercial flights from any of the affected countries.
