About 700 passengers travelling from UK to New Delhi were sent to 10-day mandatory quarantine after landing at Delhi's Indira Gandhi International Airport on Monday. The passengers were sent to quarantine post RT-PCR test at the airport. The step to send passengers to quarantine has been taken in accordance with Indian Government's stance of 'reciprocal measures' for UK nationals.

The new visa conditions have been implemented from Sunday midnight onwards. A senior government official confirmed that a total of three flights from the UK arrived at IGI airport till Monday afternoon that carried around 700 passengers, including UK nationals. As per the new rules, all passengers have to undergo a compulsory RT-PCR test followed by a 10-days quarantine at home or the destination address.&nbsp;

"A team of Delhi government is deployed at the airport to carry out the process. They are completing the formalities like getting the address of the passenger where he/she will be staying during their arrival in Delhi. Another team will be checking if the person is adhering to the quarantine rules or not," said the official.&nbsp;

He added that all preparations were done to avoid any inconvenience to the passengers, especially to UK citizens. As per the new rules, all UK nationals flying into the country will have to undertake an RT-PCR test 72 hours prior to their departure, irrespective of their vaccination status.&nbsp;

They will also be required to take a Covid-19 test on arrival and ten days of quarantine period after landing. India has already withdrawn the e-visas facility to the UK and Canadian nationals.

Hundreds of passengers from UK sent to 10-day quarantine at New Delhi airport

Team India players have tested negative in the PCR results and the fifth and final Test versus England will now go ahead as planned. On Thursday (September 9), the series decider came under the scanner after a Covid case emerged out in the Indian camp.&nbsp;

As per ESPNCricinfo, India's physio&nbsp;Yogesh Parmar had tested positive, which forced the Indian team to cancel the training session and also media commitments on Thursday. Following Parmar's positive result, there were speculations that the fifth and final Test will now not go on as planned, however, the scenario has changed after no further positive cases came out from the Indian camp in the PCR results.&nbsp;

For the unversed, Indian team is already short of its support staff, with head coach Ravi Shastri, bowling coach Bharat Arun and fielding coach R Sridhar being ruled out of the final Test, in Old Trafford, Manchester, following positive results during The Oval Test, London.&nbsp;

As for Parmar, he had taken over after lead physio Nitin Patel was forced to self-isolation during the fourth and penultimate&nbsp;after being identified as a close contact of Shastri.&nbsp;

India will, thus, go into the fifth and final Test as favourites with an unassailable 2-1 lead in the series, following their 157-run win at The Oval, London. The visitors also have a chance to win their first-ever Test series on English soil after 2007.

Do you also hate the uncomfortable and sometimes downright painful RT-PCR Covid nasal swab test? Good news, soon that might become a thing of the past, replaced by masks that can tell if the wearer has COVID-19 or not.

Researchers have developed a prototype <a href="https://www.wionews.com/topics/coronavirus">COVID-19</a> testing face mask that has the capability to do just that.

Equipped with a patch of sensors that are attached to a pad that collects the user's breath particles, this mask needs to be worn for just 15 minutes to get a result.

According to research published in the journal Nature Biotechnology, this is what the future looks like: tiny sensors incorporated into wearable fabrics like masks and jackets which could provide instant information on exposure to disease-causing pathogens such as the coronavirus.

Peter Nguyen the study’s co-author, says that these highly sensitive tests can be integrated into smart wearables “beyond what a FitBit or Applewatch can offer”.

Although up till now, these tests have been restricted for use in laboratories, they may soon be available to the public. &nbsp;

"The concept is similar to how our own skin works, where you automatically sense your environment with exquisite sensitivity without needing to actively participate in the details of the process itself," says Nguyen, a research scientist at the Wyss Institute at Harvard University.

Earlier such tests were based on living cells, which according to researchers can be too fragile and sometimes even dangerous in non-medical settings. However, in this new study, scientists were able to re-create the cell parts that sense dangerous microorganisms and freeze-dry them.

In this new study, researchers have made use of cell-free reactions which contain the tools of a living cell without the cell itself.

These freeze-dried cells can then be re-activated to begin testing by adding water similar to a "package of instant ramen noodles", says Nguyen.

In the new study, researchers used cell-free reactions that contain the tools of a living cell without the cell itself.

Since these cells are not alive, the sensors can be freeze-dried and stored for months until they are ready to be activated.

The authors of this study show that these sensors, which use CRISPR gene-editing technology, have the capability to match laboratory virus detection and they can be woven into wearable fabrics.&nbsp;

These wearable detectors might be useful for "anyone working in an environment where they might be exposed to pathogens or toxins".

The user needs to wear the prototype COVID-19 testing&nbsp;face&nbsp;mask for at least 15 minutes after its&nbsp;sensors collect their breath particles. After the fifteen minutes are up, they pierce a small pouch on the&nbsp;mask&nbsp;and water wicks the sample into the sensor for analysis.&nbsp;

A strip on the&nbsp;mask&nbsp;displays the result.&nbsp;

Wearable warning

The researchers have also developed a jacket for a liquid "exposure event", for people working in dangerous environments.&nbsp;

The jacket also employs the gene-editing tool CRISPR, to create sensors that light up when exposed to the target pathogen.&nbsp;

From tiny sensors in the fabric, Fibre optic threads in the jacket carry information to a miniature detector. This detector which is placed within the garment is the size of a small candy bar.

"In the short term, we see the wearables and especially the&nbsp;face&nbsp;masks being used in the clinic for specialised situations," he added.&nbsp;&nbsp;

However according to Nguyen in the long run, especially in cases of local outbreaks, for easy at-home testing these garments could also be used by regular people.

The Tamil Nadu government has emphasised on a slew of measures to control and act against the ongoing spike in Covid-19 cases, that are on the rise as a part of the pan-India second wave. The review meeting held here with top officials from across government departments was chaired by Chief Minister K Palaniswami. &nbsp;

Among the decisions taken and reinforced were to ensure no less than 90,000 RT-PCR tests per day to detect coronavirus infection and aggressive testing in the virus infected areas. Tracing of 25-30 contacts of the infected person, conducting fever camps. It was also decided to declare streets/residential apartments with three Covid-19 cases as micro- containment zones. &nbsp;

Admitting an infected person in a Covid Care Centre of in hospital, based on severity of infection, slapping fines against Covid-norm violators, expediting vaccination for those in the 45+ age group, following of SOP by both Government and private hospitals to reduce the mortality rate, were also mentioned. &nbsp;

The state government has also asked those, who work in cinema theatres, fruits and vegetable markets, commercial complexes to get vaccinated. It was also urged that people step out of their homes only if and when necessary, adding that they must do so while wearing masks and maintaining social distance.&nbsp;

On Monday, Tamil Nadu witnessed 6,711 new cases, which took the active cases to 46,308 and the cumulative cases to 9.40 lakh. So far, 8.8 lakhs persons have recovered, whereas 12,927 have succumbed.&nbsp;

Tamil Nadu to carry out nearly 90,000 daily RT-PCR tests amid spike in Covid-19 cases

Nearly 11 per cent of those in the national capital who tested negative for COVID-19 in rapid antigen tests (RAT) but had symptoms for the disease were found to have been afflicted by the viral infection in RT-PCR test between September 1 and November 7, according to official data.

Out of the 56,862 symptomatic patients who tested negative in rapid antigen tests, 32,903 were retested through RT-PCR and of them 3,524 were found COVID-19 positive, according to the data shared by health authorities in response to an RTI query filed by a PTI reporter.

Union Home Minister Amit Shah had chaired high-level meeting on November 15 and gave 12 instructions, following a fresh spike in the number of COVID-19 cases in the national capital.

However, there has been decrease in the number of coronavirus cases in the last few days in Delhi and the city's capacity of conducting RT-PCR tests has significantly has increased.

On Saturday, the national capital registered 3,419 new coronavirus cases, taking the infection tally to over 5.8 lakh, while the death toll rose to 9,574 with 77 more fatalities. The new cases came out of a record 81,473 tests, including 35,352 RT-PCR tests and the positivity rate slipped to 4.2 per cent from 4.78 per cent the previous day.
