Wuhan Lab Had 3 Live Bat Coronaviruses, None Matched COVID-19: Report

Beijing, May 24: The Chinese virology institute in the city where COVID-19 first emerged has three live strains of bat coronavirus on-site, but none match the new contagion wreaking chaos across the world, its director has said.

Scientists think COVID-19 -- which first emerged in Wuhan and has killed some 340,000 people worldwide -- originated in bats and could have been transmitted to people via another mammal.

But the director of the Wuhan Institute of Virology told state broadcaster CGTN that claims made by US President Donald Trump and others that the virus could have leaked from the facility were "pure fabrication".

"Now we have three strains of live viruses... But their highest similarity to SARS-CoV-2 only reaches 79.8 percent," she said, referring to the coronavirus strain that causes COVID-19.

US demands immediate start to WHO review

The United States called on the World Health Organisation on Friday to begin working immediately on investigating the source of the novel coronavirus, as well as its handling of the response to the pandemic.

One of their research teams, led by Professor Shi Zhengli, has been researching bat coronaviruses since 2004 and focused on the "source tracing of SARS", the strain behind another virus outbreak nearly two decades ago.

"We know that the whole genome of SARS-CoV-2 is only 80 percent similar to that of SARS. It's an obvious difference," she said.

"So, in Professor Shi's past research, they didn't pay attention to such viruses which are less similar to the SARS virus."

Conspiracy rumours that the biosafety lab was involved in the outbreak swirled online for months before Trump and US Secretary of State Mike Pompeo brought the theory into the mainstream by claiming that there is evidence the pathogen came from the institute.

The lab has said it received samples of the then-unknown virus on December 30, determined the viral genome sequence on January 2 and submitted information on the pathogen to the WHO on January 11.

Wang said in the interview that before it received samples in December, their team had never "encountered, researched or kept the virus."

"In fact, like everyone else, we didn't even know the virus existed," she said. "How could it have leaked from our lab when we never had it?"

The World Health Organization said Washington had offered no evidence to support the "speculative" claims.

In an interview with Scientific American, Shi said the SARS-CoV-2 genome sequence did not match any of the bat coronaviruses her laboratory had previously collected and studied.

Ninety per cent of a sample group of coronavirus-recovered patients from a prominent hospital in China's Wuhan city where the pandemic broke out have reported lung damage and five per cent of them are again in quarantine after testing positive for the virus, according to a media report on Wednesday.

A team at the Zhongnan Hospital of Wuhan University led by Peng Zhiyong, director of the hospital's Intensive Care Unit, has been conducting follow-up visits with '100 recovered patients' since April.

The first phase of this one-year programme finished in July. The average age of the patients in the study is 59.

According to the first phase results, 90 per cent of the patients' lungs are still in a damaged state, which means their lungs ventilation and gas exchange functions have not recovered to the level of healthy people, state-run Global Times reported.

Peng's team conducted a six-minute walking test with the patients. They found that the recovered patients could only walk 400 metres in six minutes while their healthy peers could walk 500 metres in the same period.

Some recovered patients have to rely on oxygen machines even three months after being discharged from the hospital, Liang Tengxiao, a doctor from the Dongzhimen Hospital, Beijing University of Chinese Medicine, was quoted as saying by the report.

Liang's team is also conducting follow-up visits with recovered patients aged above 65.

The results also showed that antibodies against the novel coronavirus in 10 per cent of the 100 patients have disappeared.

Five per cent of them received negative results in Covid-19 nucleic acid tests but positive results in Immunoglobulin M (IgM) tests, and thus have to be quarantined again, the report said.

IgM is usually the first antibody produced by the immune system when a virus attacks. A positive result in an IgM test usually means that a person has just been infected by the virus.

It is still unclear if this means these people have been infected again.

The 100 patients' immune systems have not fully recovered as they showed a low level of B cells -- - a primary force for killing viruses in the human body -- but a high level of T cells which only recognise viral antigens outside infected cells.

"The results revealed that the patients’ immune systems are still recovering," Peng said.

The patients also suffered from depression and a sense of stigma. Most of the recovered patients told the team that their families were not willing to have dinner with them at the same table, the report said.

Less than half of the recovered patients have returned to work, it said.

The findings are significant as the coronavirus first emerged in Wuhan city.

Hubei province for which Wuhan is the provincial capital has reported a total of 68,138 confirmed Covid-19 cases till now. The disease has claimed 4,512 lives in the province, according to the official data.

China reported 27 new confirmed Covid-19 cases on Tuesday, including 22 locally-transmitted cases, the National Health Commission (NHC) said on Wednesday.

London, Feb 19: UK Home Secretary Priti Patel today announced the launch of the Britain's new points-based visa system, aimed at attracting the "brightest and the best" from the world, including from India, and cutting down numbers of cheap, low-skilled workers coming to the country.

The new system will come into force from January 1, 2021 at the end of the transition period after the UK's exit from the European Union (EU) last month, which will formally end free movement of people within the economic bloc for the UK as a non-member.

The new post-Brexit system, which will apply equally to the EU and non-EU countries like India, is based on assigning points for specific skills, qualifications, salaries and professions, with visas only awarded to those who gain enough points.

"Today is a historic moment for the whole country. We're ending free movement, taking back control of our borders and delivering on the people's priorities by introducing a new UK points-based immigration system, which will bring overall migration numbers down," said Ms Patel, the senior-most Indian-origin Cabinet minister.

"We will attract the brightest and the best from around the globe, boosting the economy and our communities, and unleash this country's full potential," Ms Patel, in charge of the UK's visa and immigration system, said.

The UK Home Office said the new system is a direct response to the 2016 referendum in favour of Brexit, which was seen as a vote to end the country's reliance on cheap migrant labour and reduce overall levels of migration with tighter security.

"The new single global system will treat the EU and non-EU citizens equally. It will give top priority to those with the highest skills and the greatest talents, including scientists, engineers and academics," the Home Office said.

The Global Talent Scheme, a fast-track visa to be in operation from Friday, will also apply to the EU citizens from next year to allow highly-skilled scientists and researchers to come to the UK without a job offer.

Professor Alice Gast, President of Imperial College London, said: "British science is global. The new post-study work and Global Talent visas will help us to attract the world's brightest students and researchers, wherever they come from."

"From the race to develop a coronavirus vaccine to clean energy, British science's international collaborations drive innovation and excellence."

The government said the points threshold for the new system will be carefully set to attract the talent the UK needs. Skilled workers will need to meet a number of relevant criteria, including specific skills and the ability to speak English, to be able to work in the UK. All applicants will be required to have a job offer and, in line with the Migration Advisory Committee''s (MAC) recommendations, the minimum salary threshold will be set at 25,600 pounds - lower than the previous 30,000 pounds level for Tier 2 work visas.

The new points-based system will also expand the skills threshold for skilled workers.

Those looking to live and work in the UK will need to be qualified up to A-level or equivalent, rather than degree-level under the current system. This will provide greater flexibility and ensure UK business has access to a wide pool of skilled workers, the Home Office said.

In line with the British Prime Minister Boris Johnson's manifesto commitment in the December 2019 General Election, there will be no specific route for low-skilled workers.

"It is estimated 70 per cent of the existing EU workforce would not meet the requirements of the skilled worker route, which will help to bring overall numbers down in future," the Home Office said.

Student visa routes will also be points-based and be opened up to EU citizens from next year.

Those wishing to study in the UK will need to demonstrate that they have an offer from an approved educational institution, that they can support themselves financially and that they speak English.

To address the specific labour concerns of the agricultural sector reliant on seasonal workers from the EU, the Seasonal Workers Pilot will be expanded in time for the 2020 harvest from 2,500 to 10,000 places.

EU citizens and other non-visa nationals will not require a visa to enter the UK when visiting the UK for up to six months.

However, the use of national identity cards will be phased out for travel to the UK and the Home Office highlighted that as part of its post-Brexit offer, those EU citizens resident in the UK by December 31 2020 can still apply to settle in the UK through the EU Settlement Scheme until June 2021.

May 20: The novel coronavirus is behaving differently in patients in northeast China who have contracted it recently compared with early cases, indicating it is changing as it spreads, a prominent doctor said.

China, which has largely brought the virus under control, has found new clusters of infections in the northeastern border provinces of Jilin and Heilongjiang in recent weeks, raising concern about a second wave.

Qiu Haibo, an expert in critical care medicine who is part of a National Health Commission expert group, said the incubation period of the virus in patients in the northeast was longer than that of patients in Wuhan, the central city, where the virus emerged late last year.

"This causes a problem, as they don't have any symptoms. So when they gather with their families they don't care about this issue and we see family cluster infections," Qiu told state broadcaster CCTV in a programme broadcast late on Tuesday.

Patients in the northeastern clusters were also carrying the virus for longer than earlier cases in Wuhan, and they were taking longer to recover, as defined by a negative nucleic acid test, he said.

Patients in the northeast also rarely exhibited fever and tended to suffer damage to the lungs rather than across multiple organs, he said.

He said the virus found in the northeastern clusters was probably imported from abroad, which could account for the differences.

He did not say where he though they might have come from but both Jilin and Heilongjiang border Russia.

China reported five new coronavirus cases on Wednesday, down from six a day earlier.

Four of the new cases were local transmissions and one was imported by a traveller coming from abroad, the commission said in a statement, compared with three imported cases reported the previous day.

China's total number of coronavirus infections stands at 82,965, while the death toll 4,634.
