Coronavirus

The number of total confirmed cases in China rose to 4,515 as of 27 January, up from 2,835 a day earlier.

The country has meanwhile further tightened travel restrictions to try to curb the spread of the virus.

The city of Wuhan, thought to be the epicentre of it, is already in effective lockdown as is much of surrounding Hubei province.

The coronavirus causes severe acute respiratory infection and there is no specific cure or vaccine.

Most of the deaths have been of elderly people or those with pre-existing respiratory problems.

There are fears the coronavirus could spell a repeat of an epidemic of measles that spread from New Zealand to Samoa, where it has killed 83 people and made nearly 6000 ill since October.

Samoa's Ministry of Health has already confirmed that two Samoan sailors are in quarantine for 14 days at the Faleolo District Hospital amid fears they might be carrying China's coronavirus.

Samoa has stopped direct flights from China to reduce the risk of introducing the coronavirus.

Due to restrictions in Apia, the travellers were reportedly denied entry into Samoa yesterday after they had flown from China via Hong Kong and Nadi.

Fiji's information ministry said on return to Nadi, all six were examined by a doctor and assessed as well, with no fever.

They are in quarantine to be cleared to fly.

The ministry said all six were from Fujian province in China, and none had a history of travel to Wuhan or Hubei province where the coronavirus outbreak started.

There are currently 1,287 confirmed cases in China, 41 of whom have died.

It comes as China is begins celebrations of the Lunar New Year, one of the most important dates in its calendar.

Many events have been cancelled and a new hospital is being built in the city of Wuhan.

The virus has now spread to Europe, with three cases confirmed in France.

The first case was in Bordeaux, while the other two were in the Paris area, the French health minister said on Friday night.

And one case has been confirmed in Australia.

WHO officials made the announcement following two days of emergency committee meetings of health experts on the virus.

The coronavirus has infected more than 600 people worldwide, though mostly in China. As of Jan. 23, Chinese authorities have reported 17 deaths from the virus so far.

Cases have been reported in China, Thailand, South Korea, Taiwan, Japan and the United States. The virus causes a fever and, in some cases, difficulty breathing.

The death toll from the coronavirus sweeping through China has increased to 17 to six and more than 500 people are confirmed to have the illness, which began in Wuhan.

Health authorities say the current risk to New Zealand is low.

But Otago University's Michael Baker says the virus has already spread to several other countries, and monitoring and preparation has to be stepped up. 

He says the recent spread of the measles to the Pacific highlights the obligation New Zealand has to the region.

Anyone who concealed new cases would "be nailed on the pillar of shame for eternity", the political body responsible for law and order said.

The warning came as state media said six people had now died from the virus, which causes a type of pneumonia.

It's been confirmed the virus can pass from person to person.
