COVID-19 probably passed from bats, further studies required - WHO report

GENEVA (Reuters) - A joint WHO-China study on the origins of COVID-19 says that the virus was probably transmitted from bats to humans through another animal, and that a lab leak was 'extremely unlikely' as a cause, a summary seen by Reuters said on Monday. The WHO did not immediately reply to a query seeking comment, but said the full report by the independent experts would be published on Tuesday at 1400 GMT after member states have been briefed. The findings, first reported by the Associated Press, match what WHO experts have said previously about their conclusions following a Jan-Feb visit to the central Chinese city of Wuhan where the first human cases were detected in late 2019.

GENEVA (Reuters) - A joint WHO-China study on the origins of COVID-19 says that the virus was probably transmitted from bats to humans through another animal, and that a lab leak was "extremely unlikely" as a cause, a summary seen by Reuters said on Monday.

The WHO did not immediately reply to a query seeking comment, but said the full report by the independent experts would be published on Tuesday at 1400 GMT after member states have been briefed.

The findings, first reported by the Associated Press, match what WHO experts have said previously about their conclusions following a Jan-Feb visit to the central Chinese city of Wuhan where the first human cases were detected in late 2019.

Three laboratories in Wuhan working with coronaviruses had "well-managed", high-quality biosafety levels, and there had been no reports of compatible respiratory illness among staff during the preceding months, the report said.

Nor had they tested positive for the SARS-CoV-2 virus in subsequent blood screening for antibodies, the report said.

"In view of the above, a laboratory origin of the pandemic was considered to be extremely unlikely," it said.

WILDLIFE

Many questions remain unanswered about the virus that sparked the pandemic and the team proposed further research in bats and pangolins in China as well as in southeast Asia. Surveys of other wild animals - including civets, mink and ferrets - known to be infected by the virus were recommended.

Many early human cases were associated with the Huanan seafood market in Wuhan, which also sold wildlife, "but a similar number of cases were associated with other markets and some were not associated with any market", the report said, adding it was not possible to draw any conclusions.

WHO director-general Tedros Adhanom Ghebreysus acknowledged receipt of the report but declined to give details, telling a Geneva news briefing: "All hypotheses are on the table and warrant complete and further studies."

The report does not require any approval by member states.

The United States expects the WHO-led investigation to require further study of the virus, perhaps including a return visit to China, a senior U.S. official told reporters last week. He hoped it would be "based on science".

The probe was plagued by delays, concern over access and bickering between Beijing and Washington, which under former U.S. President Donald Trump's administration accused China of hiding the extent of the initial outbreak.

The WHO declared on Jan. 30, 2020, that COVID-19 constituted an international emergency, its highest level of alert.

France, Germany to agree to NATO role against Islamic State - sources | Reuters

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.

China's Xi says navy should become world class | Reuters

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.
