"It's only since this morning that's she's had a low grade fever."
Dr Young said the woman had been monitoring her health and contacted authorities on Thursday.
"This morning she rang up because she developed a low-grade fever of 37.6C," Dr Young said.
Blood has been taken and sent to Brisbane by plane for testing.
"There is the potential there so that's why we're treating this so seriously," Dr Young said.
However Dr Young said: "There is no risk to anyone in that community or any staff in that hospital." Dr Young also said another doctor was going through home isolation in Brisbane at present.

Dr Young said the woman had a flatmate but had not been unwell until this morning.
"Ebola virus is very difficult to transmit -- it's not like the flu or measles." Dr Young also said there was no worry about passengers on the woman's flights home.
"There is absolutely no concern for any passenger on any plane she's been on because she did not have any symptoms at all when she was on those flights." Australia has investigated three suspected cases of Ebola previously.
A woman was released from quarantine at a Perth hospital on September 23 after being cleared of the disease.
The woman had attended a conference in Africa.
And a one-year-old child was cleared of any infection after being taken to a Melbourne hospital on September 19 with suspicious symptoms.
The child had returned to Australia from west Africa five days earlier.
A third suspected case on the Gold Coast was cleared by tests after a man claiming to have spent time in Africa complained of vague symptoms while in police custody.
The Ministry of Health website currently says it is extremely unlikely someone with Ebola would arrive in New Zealand.
It said this was because the outbreak mainly affected four countries in West Africa - Sierra Leone, Guinea, Liberia and Nigeria - that very few people travelled to New Zealand from.
The website said that even in Ebola-affected countries the disease was not common and there were no direct flights to New Zealand from any of those countries.
"New Zealand's geographic isolation and the travel time from Ebola-affected countries means that an infected person would likely be too unwell to reach New Zealand," the website read.
The World Health Organisation had not recommended travel restrictions and active screening of travellers arriving in non-affected countries like New Zealand.
According to the ministry's website, people arriving in New Zealand who had visited an Ebola-affected countries in the last 30 days were being asked by a customs official about their health.
Where necessary they would be assessed by public health unit staff.
Travellers who had been in an Ebola-affected country would be provided information about the signs and symptoms of the virus and would be advised on how to seek medical help in New Zealand if they became unwell.
