Australians 'don't know what we're up against' with coronavirus threat

  Australians 'don't know what we're up against' with coronavirus threat Writer Corrine Barraclough says she believes Australians “don’t know what we’re up against,” as newly confirmed cases of the deadly coronavirus are announced across the nation. It comes as six people have tested negative for the coronavirus in Queensland meaning there are no confirmed cases across the state. However, contact tracing has also taken place in relation to patients in New South Wales after the fifth case of the deadly virus emerged in Sydney on Sunday.

" We understand that many people in the Unites States are worried about this virus," said Dr. Nancy Messonnier, director of the National Center for Of those individuals, 32 have tested negative, five have tested positive, and the remaining test results are pending. No new coronavirus cases have

US health authorities said Monday they have sequenced the genome of the first two cases of the Chinese coronavirus reported in the country and confirmed the virus has not mutated since leaving China. Nancy Messonnier, head of respiratory diseases at the Centers for Disease Control and

Robert Redfield, the CDC's director, pointed out problems with the test at a briefing on the virus, which originated in Wuhan, China, where some 200 people have died from it.

Speaking Friday at the White House, he said: "We've seen people who had a detectable virus, then they didn't have a detectable virus, and then three days later they had a detectable virus."

The problem further complicates the CDC's job of isolating and controlling the virus, which has so far been confirmed in seven separate people in the United States.

In at least one case, a patient who had not been to China caught the infection, confirming that it is capable of spreading on its own within the US.

Four possible cases of coronavirus under investigation in WA

Four people are being tested for the potentially deadly coronavirus in Western Australia, health authorities have confirmed.Western Australian chief health officer Andrew Robertson said the four cases were under investigation."These adults all meet specific travel criteria," he said."The risk to the Western Australian community remains low."WA's Health Department said there were no confirmed cases in the state to date.

The World Health Organization declared coronavirus a public health emergency of international concern at a news conference Thursday in Geneva. The first case of human-to-human coronavirus transmission in the U . S . has been confirmed, in a patient in Illinois, the Centers for Disease Control

US health authorities said Monday they have sequenced the genome of the first two cases of the Chinese coronavirus reported in the country and confirmed the virus has not mutated since leaving China.

At the same briefing, Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, also expressed concern about the tests, which he said are worse than those for other diseases.

"We don't know the accuracy of this test. People who came in were negative, then all of a sudden they were positive," he said.

"If a person has HIV and I try their blood, I can tell you 100% whether they have HIV. That's not even near the case with this."

As reported previously by Business Insider's Hilary Brueck, the coronavirus is difficult to diagnose.

Its symptoms can look a lot like the flu or a common cold, and common tests like checking somebody's temperature are not definitive.

Instead, doctors need to tests samples of mucus and saliva in a lab. This can then be analysed to see if it contains genetic material that matches the virus.

The CDC says it currently has no way to test for the virus before somebody starts displaying symptoms, meaning that there is no way to identify people during the virus' incubation period, which is up to 14 days.

Four tests for coronavirus in Qld negative

  Four tests for coronavirus in Qld negative Queensland Health says tests on four people suspected of carrying the deadly coronavirus have come back negative.The state's Chief Health Officer Dr Jeannette Young said Queensland remains free of 2019-nCoV cases, so far, after the tests were done on Monday.

Scientists at the Centers for Disease Control and Prevention also are trying to grow the coronavirus from patient samples collected in the United “ We apologize to customers for the inconvenience, but the safety of our customers and crew is always our priority,” the company said in an emailed statement.

On Friday, the US government moved to bar non-US citizens who have been to China in the past 14 days from entering the US, in the hope of containing the spread of the disease.

US citizens will be allowed back into the country, but quarantined for as long as 14 days.
