Scientists in Australia have successfully replicated the deadly Wuhan coronavirus, in what they said would be a “game changer” in the fight against a deadly epidemic which has stricken thousands.
The Peter Doherty Institute for Infection and Immunity in Melbourne yesterday announced that it had grown the novel coronavirus in cell culture from a patient sample, the first time the virus has been replicated outside China.
“Having the real virus means we now have the ability to actually validate and verify all test methods, and compare their sensitivities and specificities,” virus identification laboratory head Julian Druce said. “It will be a game changer for diagnosis.”

China was quick to sequence the genome of the coronavirus and make it public, allowing scientists around the world to develop diagnostic tools and winning praise for its efforts, in contrast to the SARS outbreak of 2002 to 2003.
However, China has not shared the virus itself with laboratories worldwide — which the Australian laboratory would now do via the WHO — although the WHO announced on Tuesday that Beijing had agreed to allow a team of international experts into the country to work with their Chinese counterparts.
Doherty Institute deputy director Mike Catton said the new finding meant scientists could now create an antibody test that would allow the coronavirus to be detected in patients who had not displayed any symptoms.
“An antibody test will enable us to retrospectively test suspected patients so we can gather a more accurate picture of how widespread the virus is, and consequently, among other things, the true mortality rate,” he said. “It will also assist in the assessment of effectiveness of trial vaccines.”
Governments, universities and medical corporations worldwide are racing to develop a vaccine against the coronavirus, which has spread to more than 15 countries.
The process could take months.
A plan by Switzerland’s right-wing People’s Party to cap the population at 10 million has the backing of almost half the country, according to a poll before an expected vote next year. The party, which has long campaigned against immigration, argues that too-fast population growth is overwhelming housing, transport and public services. The level of support comes despite the government urging voters to reject it, warning that strict curbs would damage the economy and prosperity, as Swiss companies depend on foreign workers. The poll by newspaper group Tamedia/20 Minuten and released yesterday showed that 48 percent of the population plan to vote
PARLIAMENT CHAOS: Police forcibly removed Brazilian Deputy Glauber Braga after he called the legislation part of a ‘coup offensive’ and occupied the speaker’s chair Brazil’s lower house of Congress early yesterday approved a bill that could slash former Brazilian president Jair Bolsonaro’s prison sentence for plotting a coup, after efforts by a lawmaker to disrupt the proceedings sparked chaos in parliament. Bolsonaro has been serving a 27-year term since last month after his conviction for a scheme to stop Brazilian President Luiz Inacio Lula da Silva from taking office after the 2022 election. Lawmakers had been discussing a bill that would significantly reduce sentences for several crimes, including attempting a coup d’etat — opening up the prospect that Bolsonaro, 70, could have his sentence cut to
A powerful magnitude 7.6 earthquake shook Japan’s northeast region late on Monday, prompting tsunami warnings and orders for residents to evacuate. A tsunami as high as three metres (10 feet) could hit Japan’s northeastern coast after an earthquake with an estimated magnitude of 7.6 occurred offshore at 11:15 p.m. (1415 GMT), the Japan Meteorological Agency (JMA) said. Tsunami warnings were issued for the prefectures of Hokkaido, Aomori and Iwate, and a tsunami of 40cm had been observed at Aomori’s Mutsu Ogawara and Hokkaido’s Urakawa ports before midnight, JMA said. The epicentre of the quake was 80 km (50 miles) off the coast of
RELAXED: After talks on Ukraine and trade, the French president met with students while his wife visited pandas, after the pair parted ways with their Chinese counterparts French President Emmanuel Macron concluded his fourth state visit to China yesterday in Chengdu, striking a more relaxed note after tough discussions on Ukraine and trade with Chinese President Xi Jinping (習近平) a day earlier. Far from the imposing Great Hall of the People in Beijing where the two leaders held talks, Xi and China’s first lady, Peng Liyuan (彭麗媛), showed Macron and his wife Brigitte around the centuries-old Dujiangyan Dam, a World Heritage Site set against the mountainous landscape of Sichuan Province. Macron was told through an interpreter about the ancient irrigation system, which dates back to the third century
