Chinese Researchers Find Batch Of New Coronaviruses In Bats: Report

Washington: The Chinese researchers said they had found a batch of new coronaviruses in bats, including one that may be the second-closest yet (genetically) to the Covid-19 virus.The researchers said that their discoveries in southwestern China show just how many coronaviruses are there in bats and how many have the potential to spread to people, CNN reported.In a report published in the journal Cell, the researchers from the University of Shandong said: “In total, we assembled 24 novel coronavirus genomes from different bat species, including four SARS-CoV-2 like coronaviruses.”READ: 'Levels Of Hospitalisation Going Up,' UK PM Expresses Concern Over Delta Variant, Hints At Extension Of Covid CurbsThe researchers, who collected samples from small, forest-dwelling bat...

Four cities build consortium for genomic surveillance of virus

TO COMPLEMENT the national effort led by Indian SARS-CoV-2 Consortium on Genomics (INSACOG), a consortium of four city clusters – Bengaluru, Hyderabad, New Delhi and Pune – has been established to upscale genomic surveillance on SARS-CoV-2, the virus that causes Covid-19. The new effort aims at developing strategies and building capabilities to identify variants of concern before they spread widely and cause outbreaks, said experts. The consortium aims to develop targeted sampling strategies based on granular epidemiological and clinical data. Coupled with intense environmental surveillance and advanced computational techniques, the consortium will also focus on building capabilities for real-time surveillance and epidemiology, read an official statement issued on Thursday....

GOP sees opening to revive attacks on Fauci in email trove – Times of India

WASHINGTON: Dr Anthony Fauci has been a political lightning rod since the early days of the pandemic, lionised by the left as a beacon of truth in an administration that badly mismanaged the pandemic and villainised by the right as a misguided, spotlight-seeking bureaucrat seeking to undermine former President Donald Trump. But with the release of a trove of Fauci's emails this week, Republicans' attacks on the nation's top government infectious-diseases expert have gone into overdrive. On conservative news channels, Fauci — who now serves as President Joe Biden's pandemic adviser — has been pilloried as a liar who misled the American people about the origins of Covid-19 to protect the Chinese government. In Congress, Republican calls for his resignation have grown louder, as have deman...

Coronavirus leaked from the lab or seafood market? Why finding origins into the COVID lab theory is so important – Times of India

The COVID-19 pandemic is way into its second year. With over 17.2 crore infections, 37.6 lacs deaths so far, the pandemic has changed life as we know it. Even with vaccines, there are newer variants of the virus to worry about. Even so, there is one question that remains unanswered- was it a lab or a seafood market that leaked the virus? With the U.S. and growing global authorities pressing for a more thorough investigation, it has now become more evident than ever to know where, and what caused the virus to leak. Why is the current investigation so important? The need to delve into the origins follows up a recent international WHO-led team effort to probe the origins of the spread of the SARS-COV-2 infection which was found to be "inconclusive". But what will a newer, deeper detailed ...

Coronavirus: How new COVID-19 variants come up and what makes it so concerning – Times of India

The world has been grappled with virulent strains of the SARS-COV-2 virus wreaking havoc across the world. From the strain said to have originated in Kent, UK to the much virulent double mutant virus traced in India (and now spreading across the world), mutant strains of the COVID virus are responsible for causing a lot of destruction. However, as medical experts suggest, the current mutations may not be the most dangerous yet, or mark the end of the battle yet. In fact, there could be many more variants which may spread fear. Most recently, vaccine makers from Moderna Inc. have tried to cite caution for the world not to be complacent yet.

Why scientists are concerned about leaks at biolabs – Times of India

WASHINGTON: The theory that Covid-19 might be the result of scientific experiments has thrown a spotlight on the work of the world's most secure biolabs. While the evidence linking SARS-CoV-2 to the Wuhan Institute of Virology in China is strictly circumstantial, a number of experts want tougher controls on such facilities over fears that accidental leaks could touch off the next pandemic. Here's what you should know. The Wuhan lab belongs to the most secure class, commonly referred to as biosafety level 4, or BSL4. These are built to work safely and securely with the most dangerous bacteria and viruses that can cause serious diseases for which there are no known treatment or vaccines. "There are HVAC filtration systems, so that the virus can't escape through exhaust; any waste water th...

Structural details of how SARS-CoV-2 variants escape immune response revealed – Times of India

CALIFORNIA: Fast-spreading variants of the Covid-19-causing coronavirus, SARS-CoV-2, carry mutations that enable the virus to escape some of the immune response created naturally or by vaccination. A new study by a team of researchers has revealed key details of how these escape mutations work. The scientists at Scripps Research, along with collaborators in Germany and the Netherlands, whose study appears in Science, used structural biology techniques to map at high resolution how important classes of neutralizing antibodies bind to the original pandemic strain of SARS-CoV-2--and how the process is disrupted by mutations found in new variants first detected in Brazil, the United Kingdom, South Africa and India. The research also highlights that several of these mutations are clustered i...

New vaccine blocks novel coronavirus, variants in animal study | India News – Times of India

NEW DELHI: A new vaccine candidate has proven effective in protecting monkeys and mice from the novel coronavirus and its variants that first emerged in the UK, South Africa and Brazil, as well as related bat coronaviruses that could potentially cause the next pandemic, according to a study. The finding, published in the journal Nature, is highly relevant to humans, the researchers said. The pan-coronavirus vaccine triggers neutralising antibodies via a nanoparticle composed of the coronavirus part. This part allows the vaccine to bind to the body's cell receptors, and is formulated with a chemical booster called an adjuvant, the researchers said. "We began this work last spring with the understanding that, like all viruses, mutations would occur in the SARS-CoV-2 virus, which causes CO...

Young Covid survivors not safe from reinfection: Lancet – Times of India

NEW YORK: If you are planning to avoid vaccination just because you are a Covid survivor, think twice. According to a new study, despite a prior Covid-19 infection young people can likely catch the virus again and may still transmit it to others. Even after a previous infection and the presence of antibodies, vaccination is still necessary to boost immune responses, prevent reinfection, reduce transmission, and that young person should take up the vaccine wherever possible, asserts the study published in the journal The Lancet Respiratory Medicine."Immunity is not guaranteed by past infection, and vaccinations that provide additional protection are still needed for those who have had Covid-19," said Professor Stuart Sealfon, from the Icahn School of Medicine at Mount Sinai, the US. In t...

WHO China Report: ‘Lab Leak Unlikely Source Of Covid’

New Delhi: In a draft of the joint WHO-China study on the origins of COVID-19 said that the transmission of the virus from bats to humans through another animal is the most likely scenario. The study also said that a lab leak is “extremely unlikely".According to Associated Press which received the draft of the study on Monday from a Geneva-based diplomat from a WHO-member country.

Covaxin works on Brazil, SA strains, initial findings show | India News – Times of India

PUNE: There is now preliminary evidence to suggest Covaxin may also be effective against both the Brazil and South African variants of SARS-CoV-2, a top expert from the Indian Council of Medical Research has said. A study in January had said the shot can protect against the UK variant. Dr Samiran Panda, head of the ICMR’s epidemiology and communicable diseases division, told TOI on Wednesday that the new findings are still in the early stages of scrutiny. He said, “We are yet to receive detailed information. But this should not push people away from following precautions as the virus is still spreading.” Panda said while the vaccine was proving to be effective against the variants, the recent upsurge in Covid cases in the country cannot be attributed to them. “Be it variants or old circ...

Climate change may have influenced emergence of coronavirus, says study

Climate change may have influenced the outbreaks of the novel coronavirus as well as the 2002-03 SARS pandemic virus, suggests a new study which says the global crisis triggered by the release of greenhouse gasses likely altered the distribution of bat species that carry these pathogens. The study, published in the journal, Science of The Total Environment, noted that the southern Chinese Yunnan province and neighbouring regions in Myanmar and Laos form a global hotspot of climate change-driven increase in bat richness. According to the scientists, including those from the University of Cambridge in the UK, this region coincides with the likely origin of bat-borne ancestors of the two viruses — SARS-CoV-1 and SARS-CoV-2. Based on earlier studies, the researchers said the nu...

Coronavirus: How quickly do I need a second Covid-19 vaccine shot?

How quickly do I need a second Covid-19 vaccine shot? The first Covid-19 vaccines in the U.S. require two doses a few weeks apart. People should get some degree of protection within two weeks of the first shot, with the second shot bringing about the vaccine’s full protection. For the vaccine by Pfizer and Germany’s BioNTech, the second shot is supposed to be after three weeks. For Moderna, it’s four weeks.But how closely those guidelines should be followed has been a point of difference for the United States and the United Kingdom, which has been rolling out the Pfizer vaccine and one by Astrazeneca that requires two doses given four weeks apart.To get more first shots into people and give them at least some degree of protection, the UK says it’s OK to delay the boosters ...

Here’s how protective immunity against novel coronavirus may last for over eight months

Covid-19 survivors may have protective immunity against serious disease from the SARS-CoV-2 virus for months, or even years after the infection, a study suggests. The findings, based on analyses of blood samples from 188 Covid-19 patients, suggest that nearly all survivors of the disease have the immune cells necessary to fight re-infection. “Our data suggest that the immune response is there -- and it stays,” Professor Alessandro Sette from La Jolla Institute for Immunology in the US. The researchers measured antibodies, memory B cells, helper T cells and killer T cells -- all four components of immune memory -- at the same time. The study, published in the journal Science, helps clarify some concerning data from other institutes, which showed a dramatic drop-off of Covid...

Covid-19: If I’ve already had the coronavirus, can I get it again?

If I’ve already had the coronavirus, can I get it again? It’s possible, but such cases seem to be rare. It’s not unusual to develop some immunity to a virus after an infection, since our bodies are generally better at recognizing and fighting off bugs they’ve encountered before. And that seems to be the case with the coronavirus as well, though scientists are still trying to figure out how long any protection might last.Some reinfections have been confirmed, but two new studies suggest that’s very unusual.In one, only two out of 1,265 health workers in the United Kingdom who were previously infected ended up testing positive again for the coronavirus in the following six months. In another study of people in the U.S., only 0.3% of people who had been infected tested positi...

Coronavirus: Localised herd immunity, young population behind dip in India’s Covid count?

The absolute number of people infected with COVID-19 in India may never be known but much of the scientific community agrees the downward trajectory of the disease is real and can likely be attributed to ‘localised’ herd immunity and a younger population.As scientists attempt to understand India’s sliding COVID count, the country on Tuesday recorded 16,375 new COVID-19 cases, more than six times lower than the highest daily spike of 97,894 on September 16 and the lowest in six months. While there is a glimmer of hope and India’s COVID-19 numbers are on a definite decline for a combination of reasons, a vaccination programme continues to be important, particularly given the presence of a mutant, more transmissible strain, several experts said while cautioning against inf...

Pregnant women, infants more prone to severe risks of SARS-CoV-2-infection

Research led by investigators at Massachusetts General Hospital (MGH) indicated the severe risk of Covid-19 followed SARS-CoV-2 infection into pregnant women and newborns.The study published in the journal Cell reveals lower than the expected transfer of protective SARS-CoV-2 antibodies via the placenta from mothers who are infected in the third trimester. The cause may be alterations to these antibodies after they’re produced--a process called glycosylation.The results expand on the team’s recent findings published in JAMA Network Open that pregnant women with Covid-19 pass no SARS-CoV-2 virus, but also relatively low levels of antibodies against it, to newborns.For this latest study, the scientists compared maternal antibodies against the flu (influenza), whooping cough ...
