Study claims COVID-19 immunity lasts for 6 months after first infection | Trending News in India Trending News in India

LONDON: People who’ve e had COVID-19 are highly unlikely to contract it again for at least six months after their first infection, according to a British study of healthcare workers on the frontline of fight against the coronavirus pandemic.

The findings should offer some reassurance for the more than 51 million people worldwide who have been infected with the pandemic disease, researchers at the University of Oxford said.

“This is really good news, because we can be confident that, at least in the short term, most people who get COVID-19 won’t get it again,” said David Eyre, a professor at Oxford`s Nuffield Department of Population Health, who co-led the study.

Isolated cases of re-infection with COVID-19, the disease caused by the SARS-CoV-2 virus, had raised concerns that immunity might be short-lived and that recovered patients may swiftly fall sick again.

But the results of this study, carried out in a cohort of UK healthcare workers – who are among those at highest risk of contracting COVID-19 – suggest cases of reinfection are likely to remain extremely rare.

“Being infected with COVID-19 does offer protection against re-infection for most people for at least six months,” Eyre said. “We found no new symptomatic infections in any of the participants who had tested positive for antibodies.”

The study, part of a major staff testing programme, covered a 30-week period between April and November 2020. Its results have not peer-reviewed by other scientists but were published before review on the MedRxiv website.

During the study, 89 of 11,052 staff without antibodies developed a new infection with symptoms, while none of the 1,246 staff with antibodies developed a symptomatic infection.

Staff with antibodies were also less likely to test positive for COVID-19 without symptoms, the researchers said, with 76 without antibodies testing positive, compared to only three with antibodies. Those three were all well and did not develop COVID-19 symptoms, they added.

“We will continue to follow this cohort of staff carefully to see how long protection lasts and whether previous infection affects the severity of infection if people do get infected again,” Eyre said.

Thanksgiving 2020: History, significance and importance of the holiday | Trending News in India

Thanksgiving 2020: History, significance and importance of the holiday | Trending News in India Trending News in India

New Delhi: The traditional annual holiday of Thanksgiving will be celebrated on Thursday, November 26, 2020. The Thanksgiving holiday is celebrated on various dates across the United States, Canada, Brazil, Grenada, Saint Lucia, and Liberia.

The Thanksgiving Day celebrates the harvest and other blessings of the past year. Americans generally believe that their Thanksgiving is modeled on a 1621 harvest feast shared by the English colonists (Pilgrims) of Plymouth and the Wampanoag people. 

This year, President Trump and first lady Melania Trump celebrated the Thanksgiving holiday on Tuesday with the traditional pardoning of the national Thanksgiving turkey.

The event marked Trump’s second public appearance since the General Services Administration told President-elect Joe Biden they’re ready to start the formal transition process, following brief remarks earlier in the day on the stock market.

Donald Trump exercised his pardon power during a Rose Garden event, granting the turkey named Corn a full pardon. The other turkey, Cob, will live, too. “Corn, I hereby grant you a full pardon!” Trump said, pardoning the turkey.

“We give thanks to the priceless freedoms that we’ve inherited and we ask God to watch over and protect our nation,” the outgoing president said.

Both birds are expected to live out the rest of their days at Iowa State University.

The holiday is often the busiest time of the year as family members either travel away for a holiday or gather to celebrate with one another. This holiday is particularly rich in legend and symbolism, and the traditional fare of the Thanksgiving meal typically includes turkey, bread stuffing, potatoes, cranberries, and pumpkin pie. 

The Thanksgiving was not a traditional holiday till October 3, 1863, when Preident Abraham Lincoln during the Civil War, proclaimed a national day of thanksgiving to be celebrated on Thursday, November 26.

Since then the holiday has been annually proclaimed by every president and the date chosen is the last Thursday in the month of November.

Earth had a minimoon for around 3 years before it drifted away few months ago | Trending News in India

Earth had a minimoon for around 3 years before it drifted away few months ago | Trending News in India Trending News in India

Earlier this year, a minimoon was found orbiting Earth by a group of astronomers. The minimoon has now drifted away but astronomers said that more such minimoons will be found orbiting Earth in the future.

The minimoon was first spotted by astronomers at the Catalina Sky Survey in Arizona. The astronomers spotted a dim object called 2020 CD3 in February but they were not sure whether it was a a minimoon or an artificial object like a rocket booster. But Grigori Fedorets at Queen’s University Belfast and his team used several telescopes to observe the object closely in order to find out more about its composition and other details.

Fedorets and his team found that the celestial body had a diameter of about 1.2 metres and it was probably made of silicate rock. “Based on simulations, the average capture time for minimoons is only nine months, so this was captured for a longer time than is expected,” says Fedorets. “But this object flew very close to the [regular] moon, and that put it into a more stable orbit.”

According to astronomers Minimoon or 2020 CD3 drifted out of the orbit of Earth in March, but the researchers are hopeful that once the Vera C. Rubin Observatory is completed in Chile it will help in detecting many more objects like it.

“We could detect a minimoon once every two or three months in the best-case scenario. In the worst case scenario, maybe once a year,” Fedorets was quoted as saying by newscientist.com.

United Kingdom ‘s four nations to relax COVID-19 restrictions to save Christmas | Trending News in India

United Kingdom 's four nations to relax COVID-19 restrictions to save Christmas | Trending News in India Trending News in India

LONDON: The four nations of the United Kingdom have agreed to relax COVID-19 restrictions for Christmas to allow up to three households to meet at home for five days.

England, Scotland, Wales and Northern Ireland have taken differing approaches to handle the pandemic so far but the leaders of the devolved nations reached an agreement with London on Tuesday on rules governing the festive period.

Three households will be able to form a “Christmas bubble”, allowing them to meet up at home, places of worship and in outdoor public places but not at indoor hospitality or entertainment venues from December 23 until December 27 under the plans.

“People want to be with their loved ones and those close to them for what is the most important holiday of the year,” senior minister Michael Gove said on Tuesday.

Limits on travel will also be scrapped so that people can meet up, with an additional day on either side for those going to and from Northern Ireland.

A national lockdown in England is due to end next week after which different parts of the country will face varying restrictions as part of a tiered system announced by Prime Minister Boris Johnson.

A decision is expected later this week on which areas will fall into the different categories.

The United Kingdom has one of the highest tolls from the coronavirus pandemic, reaching 55,838 deaths within 28 days of a positive test, according to government data published on Tuesday.

“The virus won’t take time off, so please be cautious,” said Scotland`s First Minister Nicola Sturgeon. “If you can, stay at home with your own household.”
