Air Filters Can Effectively Kill Covid-19 Particles, Says New Hospital Study

Published

on

A new study has shed light on how air filters can be effectively used to remove nearly airborne traces of Covid-19 in a given environment.

Conducted by the University of Cambridge and Addenbrooke’s Hospital, the study could help limit transmission in already contagious zones for Covid-19 and other air borne viral infections that have the potential to spread quickly.

Published in the Clinical Infection Diseases journal, the study suggests using portable air filtration and sterilisation devices with ultra-violet capabilities to prevent transmission of Covid-19.

How the process works

Led by Dr. Vilas Navapurlar, SkyNews quoted the intensive care specialist as saying that reducing airborne transmission is a key part of protecting not only the patients but healthcare workers at any hospital.

While PPE kits remain extremely effective at limiting Covid-19’s spread, air filters can play a more robust role in keeping the air virus-free.

The best part? Air filtration devices are rather modestly priced and can be spread out across hospitals in case another Covid-19 wave were to hit the world, signs of which are appearing in European countries at the moment.

To test out the hypothesis, researches installed particulate air filters/ultra-violet sterilisers to filter out particles. It is a device made up of thousands of fibres knit together to effectively filter out particles.

The series of machines operated continuously for seven days, effectively filtering most possible volume of air in every room 5-10 times.

Using a PCR-like method, doctors used air samples to figure out the concentration of Covid-19 aerosol particles. They found the filters not only eliminated covid germs but also helped cut down bacterial and fungal particles.

Donald Trump Resurfaces Ilhan Omar Conspiracy Theory, Says She ‘Abandoned’ Her Country

Published

on

Former President Donald Trump has accused Representative Ilhan Omar of “abandoning her former country,” while repeating an unsubstantiated conspiracy theory about the congresswoman.

Omar arrived in the U.S. in 1995 as a 12-year-old refugee from Somalia and became an American citizen five years later. Trump lashed out at Omar in a statement issued on Tuesday. Trump’s remarks came amid a firestorm of controversy surrounding anti-Muslim comments about the Minnesota Democrat from Representative Lauren Boebert, a staunch supporter of the former president.

“Congresswoman Ilhan Omar should apologize for marrying her brother, committing large-scale immigration and election fraud, wishing death to Israel, and for essentially abandoning her former country, which doesn’t even have a government,” Trump said. “Exactly what she’d like to see for the United States!”

A conspiracy theory claiming that Omar secretly married her brother in order to help him establish U.S. residency has been repeated often by figures on the right including Trump. Although the claim would amount to immigration fraud if it were true, there is no credible evidence that proves the conspiracy. The theory posits that Omar’s ex-husband Ahmed Nur Said Elmi, a U.K. citizen, was actually her brother.

In addition to a lack of evidence to substantiate the claim, Omar and her confirmed siblings became U.S. citizens. A theoretical additional sibling could have applied for permanent residency on the basis that they were the sibling of a citizen, rather than resorting to fraud. The congresswoman has called the allegations “absurd and offensive.”

In remarks similar to his statement on Tuesday, Trump said that Omar “came in here and married her brother or something” during an October 2020 campaign stop in Florida, while also asserting that she “from a place that doesn’t even have a government.”

Trump tweeted in July 2019 that Omar and the other progressive lawmakers collectively known as “the Squad” should “go back and help fix the totally broken and crime infested places from which they came,” despite the fact that Omar is the only foreign-born member of the group.

Boebert recently received backlash for calling Omar a member of the “Jihad Squad” on the House floor. The Colorado Republican attracted further criticism after suggesting that a Capitol police officer could rest easy around Omar because she was not carrying “a backpack,” a remark that Omar said was an attempt to label her a “suicide bomber.”

Boebert issued a tweet apologizing “to anyone in the Muslim community I offended” while insisting that criticism of her remarks was an “unnecessary reaction. ” She later called Omar, ostensibly to apologize over the phone. Omar said that Boebert did not apologize during the call but “refused to publicly acknowledge her hurtful and dangerous comment” and “doubled down on her rhetoric.” Omar ended the call by hanging up.

Although most Republican members of Congress have remained silent about Boebert, some have backed her up. Georgia Representative Marjorie Taylor Greene referred to Omar as a “Jihad Squad” member following the controversy, while Representative Madison Cawthorn of South Carolina maintained that criticism of Boebert’s remarks were unfair attempts to get her “canceled.”

A few Republicans have also rebuked Boebert and her comments about Omar. South Carolina Representative Nancy Mace told CNN that she condemned the comments on Sunday and Congressman Adam Kinzinger of Illinois recently tweeted that Boebert was “TRASH.”

Newsweek reached out to Representative Omar’s office for comment.

Tracking variants: Centre asks states to send all samples from Covid hotspots

Published

on

TIGHTENING ITS genome sequencing measures to ensure early detection of new variants, including Omicron, the Union Health Ministry has asked states to send “100 per cent samples” from Covid hotspots, starting with two recent clusters in Karnataka’s Dharwad and Maharashtra’s Thane, The Indian Express has learnt.

On Tuesday, during a high-level review meeting chaired by Union Health Secretary Rajesh Bhushan, the states were advised to send “all positive samples” for genome sequencing to designated INSACOG labs “in a prompt manner”. Earlier, only about five per cent of samples from positive cases detected by RT-PCR tests were sent for genome sequencing.

To begin with, top Government sources told The Indian Express, the Centre has told authorities to send all samples from the cluster of cases reported from a medical college in Dharwad and an old-age home at Bhiwandi in Thane.

“We have told the states that whenever you have emerging hotspots and clusters of new cases, you should get 100 per cent of the genome sequenced. It is being done in Dharwad, where they had more than 240 cases in one institution, and in Bhiwandi, where 60 cases were detected in an old age home. We have told the states that wherever you have such a number, there should be mandatory genome sequencing,” sources said.

On Tuesday, the Centre told states to ensure “physical visits” to the homes of passengers from “at-risk” countries to monitor home isolation. “The status of those who are negative after the retest on the eighth day” will also be “physically monitored by the state administration”, it said. The states have been told that international passengers from “at-risk” countries should be advised to wait at airports till the report comes and “not book connecting flights”.

During the meeting, ICMR D-G Dr Balram Bhargava said Omicron does not escape RT-PCR and Rapid Antigen tests. The Centre conveyed that the flagship “Har Ghar Dastak” campaign has been extended till December 31.
