French hospital tests new breathalyser machine to detect COVID-19

LYON, France (Reuters) - A hospital in the French city of Lyon is testing patients with a new machine that enables them to breathe into a tube to see whether they have COVID-19 in a matter of seconds.
The machine is entering a second trial phase after three months of use on dozens of people, among whom about 20 had the virus and the others did not. Unlike the uncomfortable standard PCR (polymerase chain reaction) tests, it is not invasive and provides an immediate result.
"It's the same principle as a classic breathalyser test," Christian George, director of research at the National Centre of Scientific Research at the la Croix-Rousse hospital, told Reuters.
The device uses a highly sensitive mass spectrometer to measure volatile organic compounds in exhaled breath, according to researchers.
"The machine will register the molecules in the exhaled air and then detects the traces of the sickness."
Jean-Christophe Richard, head of intensive care at the hospital, said the objective was to have the machine fully operational by the end of the year.
"This type of quick test means we will have the results straightaway and can then move the patient to the right area of the hospital. As we now have a few efficient treatments, the quicker we can diagnose the quicker we can treat them," he said.
Bruno Lina, an independent virus expert who has been consulted on the machine, said it was a step in the right direction, but at this stage was too expensive for widespread distribution in hospitals.
"If our hypothesis is proved correct we could see second or third generation machines that cost less and that would specifically home in on the markers of the infection that we have identified," Lina, who heads the National Enterovirus and Parechovirus Reference Centre, said.

By Robin Emmott and John Irish | BRUSSELS/PARIS BRUSSELS/PARIS France and Germany will agree to a U.S. plan for NATO to take a bigger role in the fight against Islamic militants at a meeting with President Donald Trump on Thursday, but insist the move is purely symbolic, four senior European diplomats said.The decision to allow the North Atlantic Treaty Organization to join the coalition against Islamic State in Syria and Iraq follows weeks of pressure on the two allies, who are wary of NATO confronting Russia in Syria and of alienating Arab countries who see NATO as pushing a pro-Western agenda."NATO as an institution will join the coalition," said one senior diplomat involved in the discussions. "The question is whether this just a symbolic gesture to the United States
BEIJING Chinese President Xi Jinping on Wednesday called for greater efforts to make the country's navy a world class one, strong in operations on, below and above the surface, as it steps up its ability to project power far from its shores.China's navy has taken an increasingly prominent role in recent months, with a rising star admiral taking command, its first aircraft carrier sailing around self-ruled Taiwan and a new aircraft carrier launched last month.With President Donald Trump promising a US shipbuilding spree and unnerving Beijing with his unpredictable approach on hot button issues including Taiwan and the South and East China Seas, China is pushing to narrow the gap with the U.S. Navy.Inspecting navy headquarters, Xi said the navy should "aim for the top ranks in the world", the Defence Ministry said in a statement about his visit."Building a strong and modern navy is an important mark of a top ranking global military," the ministry paraphrased Xi as saying.
