China says virus spreading between humans as WHO is set to meet
China has confirmed human-to-human transmission in the outbreak of a new SARS-like virus as the number of cases soared and authorities on Tuesday said a fourth person had died.
The news came as the World Health Organisation (WHO) said it would consider declaring an international public health emergency over the outbreak.
The coronavirus, which has spread to three other Asian countries and infected more than 200 people in China, 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.
The discovery of human-to-human transmission comes as hundreds of millions of people are criss-crossing the country in packed buses, trains and planes this week to celebrate the Lunar New Year with relatives.
Enhanced screening measures, including fever checks, have been set up at airports in Australia, Bangladesh, Hong Kong, Nepal, Singapore, Thailand, Taiwan and the US, with particular attention on arrivals from the central Chinese city of Wuhan, the epicentre of the outbreak.
Health authorities there, where a seafood market has been identified as the centre of the outbreak, said on Tuesday that an 89-year-old man became the fourth person to die from the virus and 15 medical staff had been infected.
A second case was also confirmed in Shanghai on Tuesday, while five people have been diagnosed with the illness in Beijing.
The virus has also reached Japan, Thailand and South Korea, with four people hospitalised after visiting Wuhan.
A man showing symptoms of the disease who had traveled to the Chinese city has been put in isolation in Australia as health officials await test results, authorities said on Tuesday.
Rare WHO meeting
Zhong Nanshan, a renowned scientist at China's national health commission, confirmed the virus was being transmitted between humans, state media reported late on Monday.
The WHO had previously identified animals as the likely primary source, but had warned of "some limited human-to-human transmission".
Zhong told CCTV that patients can contract the virus without having visited Wuhan.
He said 14 medical staff had been infected but it was not clear if he was referring to the Wuhan cases.
In southern Guangdong province, two patients were infected by family members who visited Wuhan, he told CCTV.
The WHO said a key emergency committee would meet on Wednesday to determine whether to declare an international public health emergency.
The agency has only used the rare label 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 number of people hit by the new coronavirus is expected to rise, especially with increased monitoring and testing for the disease.
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 Chinese government announced on 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.
China's President Xi Jinping said the virus must be "resolutely contained" and stressed that information must be released "in a timely manner", in his first public comments on the outbreak on Monday.
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.
"The speed of response is testimony to improved global preparedness," said Jeremy Farrar, director of British health care foundation Wellcome Trust.
"But we must not be complacent. There is still much to be done to ensure countries across the world are protecting people from epidemic threats of diseases known and unknown," he said.
