New China virus: US announces first case

The Centers for Disease Control said the virus, which originated in China, had been diagnosed in a US resident who arrived in Seattle from China.

The virus, which spread from the Chinese city of Wuhan, has infected almost 300 people, and six have died.

North Korea has temporarily closed its borders to foreign tourists in response to the threat, a tour operator says.

The patient diagnosed in the US – reported to be a man in his 30s – returned from Wuhan on 15 January, the CDC said.

“The patient sought care at a medical facility in the state of Washington, where the patient was treated for the illness,” it added in a statement.

“Based on the patient’s travel history and symptoms, healthcare professionals suspected this new coronavirus.”

Laboratory testing of a clinical specimen confirmed the diagnosis on 20 January, the CDC statement continued.

Where has the virus spread?
Earlier on Monday, Chinese officials confirmed for the first time that the virus could pass from person to person.

At the same time Chinese state media said six people had died from the infection, which causes a type of pneumonia.

A total of 291 cases have now been reported across major cities in China, including Beijing and Shanghai. However, most are in Wuhan, the central city of 11 million people at the heart of the outbreak.

The disease was first identified there late last year, and the outbreak is believed to be linked to a seafood market that also sells live animals.

Aside from the United States, two cases have been identified in Thailand, one in Japan, one in South Korea and one in Taiwan. All those infected had recently returned from Wuhan.

Authorities in several countries, including Australia, Singapore, Hong Kong, Taiwan and Japan have stepped up screening of air passengers from Wuhan. US authorities last week announced similar measures at airports in San Francisco, Los Angeles and New York. They have now announced plans to introduce similar measures at airports in Chicago and Atlanta this week.

In Australia, a man who had travelled to Wuhan has been placed in isolation and is undergoing tests. China is the largest source of tourists to Australia, with more than a million Chinese citizens visiting last year.

But the measures being put in place by North Korea are the strictest so far.

A report by the Centre for Global Infectious Disease Analysis at Imperial College, London, suggested there could be more than 1,700 infections. However, Gabriel Leung, the dean of medicine at the University of Hong Kong, put the figure closer to 1,300.
