A Goulburn resident has been detected with coronavirus and is in isolation in Darwin.
The 52-year-old man had returned from Singapore on February 28 on a Qantas flight QF02 and subsequently travelled to Darwin from Sydney on March 3 on the QF840 flight.
His movements between February 28 and March 3 are unknown at this stage.
"He was travelling with a companion to Darwin and after his arrival he was advised his travel companion had coronavirus," a NT Health spokesperson said.
"He immediately self isolated and contacted health authorities."
"He was tested at a local GP where all the precautions were taken, and otherwise remained in his hotel room until the test results were confirmed, at which point he drove himself to Royal Darwin Hospital, where he was met by the Public Health Unit and admitted and remains in isolation."
After his arrival to Darwin, he drove to the Woolworths complex in Darwin CBD and later checked into his accommodation at the Ramada on Wyndham.
The case was detected on March 4 and is the first confirmed case in the Northern Territory.
The Top End Health Service Public Health Unit is tracking and contacting passengers who could have come in close contact with the man and were on the same flight with him, in the same accommodation and could have been at the Woolworths store.
People who were on the flight, staying at the accommodation or who visited the Woolworths complex are advised to monitor their health. They are not required to self-isolate or get tested unless they develop any respiratory symptoms.
The contacts and movements of the latest cases are being established.
This brings the total number of cases detected in NSW to 26.
WHO suggests the virus can cause mild, flu-like symptoms as well as more severe disease.
Patients have a range of symptoms: fever (83-98 per cent), cough (68 per cent) and shortness of breath (19-35 per cent), based on the latest data.
Based on current data, 81 per cent of cases seem to have mild disease, about 14 per cent appear to progress to severe disease, and some 5 per cent are critical.
Risk factors for severe disease are older age and comorbidities.
According to the World Health Organisation, a total of 95,265 have been reported cases of COVID-19 globally. Of those, 3281 people have died.
A total of 43 reported cases of COVID-19 have been reported in Australia, as of March 3, and one of those has resulted in a death.
It was a 95-year-old resident at a Macquarie Park aged-care facility who died on Tuesday.
