Asian countries on Tuesday ramped up measures to block the spread of a new virus as the death toll in China rose to six and the number of cases jumped to almost 300, raising concerns in the middle of a major holiday travel rush.

From Australia to Thailand and as far as Nepal, nations stepped up fever checks of passengers at airports to detect the SARS-like coronavirus, which first emerged in the central Chinese city of Wuhan.

Fears of a bigger outbreak rose after a prominent expert from China’s National Health Commission confirmed late Monday that the virus can be passed between people.

Authorities previously said there was no obvious evidence of person-to-person transmission and animals were suspected to be the source, as a seafood market where live animals were sold in Wuhan was identified as the centre of the outbreak.

The confirmation of human transmission comes as hundreds of millions of people are crisscrossing China in packed buses, trains and planes this week to celebrate the Lunar New Year with relatives.

Almost 80 new cases have been confirmed, bringing the total number of people hit by the virus in China to 291, with the vast majority in Hubei, the province where Wuhan lies, and others in Beijing, Shanghai and Guangdong, according to the National Health Commission. State media said one case was found in Zhejiang province.

Taiwan’s Center for Disease Control (CDC) personnel using thermal scanners to screen passengers arriving on a flight from China’s Wuhan province, where a SARS-like virus was discovered and has since spread, at the Taoyuan International Airport.

Wuhan mayor Zhou Xianwang told state broadcaster CCTV that the death toll had risen from four to six.

China said it would attend a special World Health Organization meeting on Wednesday which will determine whether to declare a rare global public health emergency over the disease, which was detected in Thailand, Japan and South Korea among four people who had visited Wuhan.

The coronavirus has caused alarm because of its genetic similarities to Severe Acute Respiratory Syndrome (SARS), which killed nearly 650 people across mainland China and Hong Kong in 2002-2003.

Fever checks

At four airports in Thailand, authorities introduced mandatory thermal scans of passengers arriving from high-risk areas of China. Anyone exhibiting signs of fever will be quarantined for 24 hours for monitoring.

Around 1,300 passengers are expected each day in Thailand from Wuhan over Chinese New Year, which starts on Friday.

In Hong Kong, where memories of SARS still haunt the city, authorities said they were on “extreme high alert”, with passengers from Wuhan required to fill out health declarations and face possible jail time if they do not declare symptoms.

“We are … preparing for the worst. We have not lowered our guard,” Hong Kong’s number two leader, Chief Secretary Matthew Cheung, told reporters.

Taiwan went onto its second-highest alert level for those travelling to and from Wuhan, advising visitors to avoid visiting any live poultry markets while screening has been stepped up at airports.

Enhanced screening measures have also been set up at airports in Australia, Bangladesh, Nepal, Singapore, and the United States.

A man showing symptoms of the disease who had travelled to Wuhan has been put in isolation in Australia as health officials await test results, authorities said Tuesday.

In China, the government announced Tuesday it was classifying the outbreak in the same category as SARS, meaning compulsory isolation for those diagnosed with the disease and the potential to implement quarantine measures on travel.

In Wuhan, authorities banned tour groups and police were conducting spot checks for live poultry or wild animals in vehicles leaving and entering the city, state media said.

Passengers were being screened for fever at the airport, railway stations and bus terminals. Those with fevers would be registered, handed masks and advised to see a doctor, and they would not have to pay to change their tickets.

WHO meeting

Zhong Nanshan, a renowned scientist at the National Health Commission, raised the alarm when he said on Monday that patients can contract the virus without having visited Wuhan, though he added that it was milder than SARS.

The WHO had previously identified animals as the likely primary source, but had warned of “some limited human-to-human transmission”.

Doctors at the University of Hong Kong released a study on Tuesday estimating that there have been 1,343 cases of the new virus in Wuhan. Scientists at Imperial College in London said last week the number was likely closer to 1,700.

The WHO has only called a global public health emergency a handful of times, including during the H1N1 — or swine flu — pandemic of 2009 and the Ebola epidemic that devastated parts of West Africa from 2014 to 2016.

The Communist government was accused of covering up the SARS outbreak in 2003 but some foreign experts have praised the swift release of information on this new virus.

“China is willing to continue to deepen international cooperation, join hands with the international community to respond to the epidemic, and jointly maintain regional and global health security,” foreign ministry spokesman Geng Shuang told reporters. (AFP)
