More People Quarantined In Australia Over Coronavirus Fears

Several people have been quarantined and are undergoing testing over fears they have contracted the deadly and highly contagious coronavirus.

Of those currently in quarantine, two are in Queensland and two are in NSW -- with the number set to rise.

Two further people were quarantined in NSW, it was announced on Friday morning, but by Friday afternoon they had been released.

A spokesperson for the NSW Department of Health said the locations of the patients under testing would not be disclosed until their diagnoses were confirmed.

'We will update the public immediately of any confirmed cases and need to disclose a person’s movements," the statement read.

The death toll currently stands at 25, with more than 800 people infected throughout China.

China's health authorities issued the update on Friday, after the World Health Organisation declared it an emergency but stopped short of declaring the epidemic of international concern.

China's National Health Commission said 830 cases had been confirmed so far and 25 people had died as of Thursday.

Most of the cases are in the central Chinese city of Wuhan, where the virus is believed to have originated late last year.

Non-fatal cases have been found in at least seven other countries.

Health officials fear the transmission rate could accelerate as hundreds of millions of Chinese travel at home and abroad during week-long holidays for the Lunar New Year, which begins on Saturday.
