The woman began feeling unwell at work on Thursday after returning from Iran, where the disease has reached epidemic levels.
She is currently being treated at the Gold Coast University Hospital.
Health authorities are now trying to track down any clients she treated on Thursday.
The beautician saw up to 40 people at a Southport salon on Thursday before she started to develop symptoms and went home.
“She saw a number of clients each for brief interactions, so we believe the risk is incredibly low,” Queensland’s Chief Health Officer Jeannette Young said.
The other case is a 79-year-old West Australian woman has tested positive after being evacuated from the Diamond Princess cruise ship in Japan.
There are now 25 confirmed cases across Australia.
Dr Young said the number of countries that have contracted the coronavirus is increasing each day.
“So it’s very hard for individuals to work out which country is at risk,” she told reporters in Brisbane on Saturday.
“It’s really a message now, if you have been overseas, you come back to Queensland, you feel unwell with any symptoms, that you go and get advice.”
Dr Young said that older people are more likely to suffer life-threatening symptoms from the disease.
“Children are doing well. They’re getting the disease but with minimal symptoms,” she said.
“The group that’s most at risk is those people who are older, or people with diabetes, cardiovascular disease and hypertension.”
Coronaviruses are a large group of viruses that are common among animals and cause illness ranging from the common cold to more severe diseases such as Severe Acute Respiratory Syndrome (SARS).
The name comes from the Latin word “corona,” meaning a halo or crown, which the viruses resemble when viewed under a microscope.
The current outbreak is most likely to have started from people who picked it up from a fresh food market, also known as a ‘wet market’, in Wuhan, China.
Although it is a new strain among humans, it is likely the virus was being transmitted among different animal species and then transferred to humans at the market.
What are the symptoms of coronavirus?
In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
The incubation period – between infection and showing any symptoms – lasts up to 14 days, according to the WHO.
But some researchers say it may be as long as 24 days.
And Chinese scientists say some people may be infectious even before their symptoms appear.
How worried should you be about contracting coronavirus?
According to WHO, If you are not in an area where COVID-19 is spreading, or if you have not travelled from one of those areas or have not been in close contact with someone who has and is feeling unwell, your chances of getting it are currently low.
In Australia, the low number of confirmed cases means a reduced likelihood of infection.
Despite this, authorities are urging people to remain vigilant and continue to monitor their own symptoms, maintain their hygiene, obey travel bans to areas with high infection rates and seek professional medical advice if they have concerns.
How to protect yourself and others from infection
The WHO says standard recommendations to prevent spread include regular hand washing, covering mouth and nose when coughing and sneezing and thoroughly cooking meat and eggs.
Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.
If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others.
Is there a cure for coronavirus?
There is no cure or vaccine for the virus however hope for treating the virus could be on the horizon with the first US study of a drug to treat the illness on the way.
A clinical trial to evaluate the safety and effectiveness of the antiviral drug, Remdesivir, in adults diagnosed with coronavirus started at the University of Nebraska Medical Center in Omaha, the National Institutes of Health said.
In Australia, health authorities are encouraging people to receive their flu shot as early as possible to avoid added pressure on the health system as flu-season approaches.
COVID-19 is also more dangerous if you have a pre-existing condition or weak immune system meaning protecting yourself from other illnesses is a practical step to preventing life-threatening symptoms.
What is Australia doing to prevent the spread of COVID-19?
Australian authorities are taking a “rings of containment” approach to limiting the spread of the virus, now formally known as COVID-19, by trying to contain any confirmed cases to individuals, families or affected units.
For a small outbreak, public health units would trace who infected people had come into contact with and isolate people where appropriate to try to prevent further spread.
In the case of a bigger spread, they would focus on limiting the speed at which the virus is being transmitted.
