Does it behove Rahul to label all Modis as thieves: PM

Thiruvananthapuram, May 22: Domestic flyers arriving in Kerala must undergo strict home quarantine as per the lockdown guidelines, in view of increasing COVID-19 cases in the state, Health Minister K K Shailaja said on Friday.

"Even if the domestic flight services resume, those coming in must remain under strict home quarantine as per the guidelines.

There is no change in that. Most people will be coming from the major hotspots of the country," she said.

Announcing the resumption of domestic flight services from May 25, the Civil Aviation Ministry had indicated on Thursday that it was not in favour of quarantining passengers on short-haul flights.

However, the Assam government has made it mandatory for all air passengers coming to that state to stay in quarantine for 14 days.

Apart from the health department and the local self government institutions, Shailaja said the people of Kerala must also ensure that every returnee to the state remained under strict home quarantine in order to curb the spread of the disease.

"We need to strictly keep under observation all those who come fromoutside the state and make sure that they do not come into contact with others including their family members.

They should be effectively remain under room quarantine at their residence," she said.

The state reported 690 cases after 24 more tested positive for coronavirus on Thursday.

As of now over 80,000 people are under observation across the state.

On the death of a 73-year-old woman, who came from Mumbai, on Thursday, the minister said, "Khadijakuttycame from Mumbai along with three others. She alighted at Chavakkad. Her son who picked her up from there took her to the govt hospital as she was tired. She was given good care."

"However, as her condition worsened, had taken a decision to sent her to the medicalcollege. Her swab test was taken and she was tested positive, but she passed away," Shailaja said.

The minister sounded a word of caution that there would be an increase in cases in the coming days as the influx of people coming from abroad and other states would continue.

"We cannot prevent anyone from coming. They are our brothers and were suffering there. We need to save those who come here and also those who are here," the Minister said.

Shailaja said the southern state had successfully managed the first two phases of the viral outbreak in January and March.

"There were three deaths. But we managed to save the rest of the people including a 93-year-old man," she said.

The Minister further said the situation in the state changed after flight services resumed and the border roads were re-opened after May 7.

"Our fatality rate is low and recovery rate is high.

After May 7, when the flight restrictions were lifted and people from other states started coming in, we reported 188 cases.

At least 90 per cent of the positive cases came from outside and the rest are their contacts," she noted.

The coronavirus can stay aloft for hours in tiny droplets in stagnant air, infecting people as they inhale, mounting scientific evidence suggests.

This risk is highest in crowded indoor spaces with poor ventilation, and may help explain superspreading events reported in meatpacking plants, churches and restaurants.

It’s unclear how often the virus is spread via these tiny droplets, or aerosols, compared with larger droplets that are expelled when a sick person coughs or sneezes, or transmitted through contact with contaminated surfaces, said Linsey Marr, an aerosol expert at Virginia Tech.

Aerosols are released even when a person without symptoms exhales, talks or sings, according to Marr and more than 200 other experts, who have outlined the evidence in an open letter to the World Health Organization.

What is clear, they said, is that people should consider minimizing time indoors with people outside their families. Schools, nursing homes and businesses should consider adding powerful new air filters and ultraviolet lights that can kill airborne viruses.

What does it mean for a virus to be airborne?

For a virus to be airborne means that it can be carried through the air in a viable form. For most pathogens, this is a yes-no scenario. HIV, too delicate to survive outside the body, is not airborne. Measles is airborne, and dangerously so: It can survive in the air for up to two hours.

For the coronavirus, the definition has been more complicated. Experts agree that the virus does not travel long distances or remain viable outdoors. But evidence suggests it can traverse the length of a room and, in one set of experimental conditions, remain viable for perhaps three hours.

How are aerosols different from droplets?

Aerosols are droplets, droplets are aerosols — they do not differ except in size. Scientists sometimes refer to droplets fewer than 5 microns in diameter as aerosols. (By comparison, a red blood cell is about 5 microns in diameter; a human hair is about 50 microns wide.)

From the start of the pandemic, the WHO and other public health organizations have focused on the virus’s ability to spread through large droplets that are expelled when a symptomatic person coughs or sneezes.

These droplets are heavy, relatively speaking, and fall quickly to the floor or onto a surface that others might touch. This is why public health agencies have recommended maintaining a distance of at least 6 feet from others, and frequent hand washing.

But some experts have said for months that infected people also are releasing aerosols when they cough and sneeze. More important, they expel aerosols even when they breathe, talk or sing, especially with some exertion.

Scientists know now that people can spread the virus even in the absence of symptoms — without coughing or sneezing — and aerosols might explain that phenomenon.

Because aerosols are smaller, they contain much less virus than droplets do. But because they are lighter, they can linger in the air for hours, especially in the absence of fresh air. In a crowded indoor space, a single infected person can release enough aerosolized virus over time to infect many people, perhaps seeding a superspreader event.

For droplets to be responsible for that kind of spread, a single person would have to be within a few feet of all the other people, or to have contaminated an object that everyone else touched. All that seems unlikely to many experts: “I have to do too many mental gymnastics to explain those other routes of transmission compared to aerosol transmission, which is much simpler,” Marr said.

Can I stop worrying about physical distancing and washing my hands?

Physical distancing is still very important. The closer you are to an infected person, the more aerosols and droplets you may be exposed to. Washing your hands often is still a good idea.

What’s new is that those two things may not be enough. “We should be placing as much emphasis on masks and ventilation as we do with hand washing,” Marr said. “As far as we can tell, this is equally important, if not more important.”

Should I begin wearing a hospital-grade mask indoors? And how long is too long to stay indoors?

Health care workers may all need to wear N95 masks, which filter out most aerosols. At the moment, they are advised to do so only when engaged in certain medical procedures that are thought to produce aerosols.

For the rest of us, cloth face masks will still greatly reduce risk, as long as most people wear them. At home, when you’re with your own family or with roommates you know to be careful, masks are still not necessary. But it is a good idea to wear them in other indoor spaces, experts said.

As for how long is safe, that is frustratingly tough to answer. A lot depends on whether the room is too crowded to allow for a safe distance from others and whether there is fresh air circulating through the room.

What does airborne transmission mean for reopening schools and colleges?

This is a matter of intense debate. Many schools are poorly ventilated and are too poorly funded to invest in new filtration systems. “There is a huge vulnerability to infection transmission via aerosols in schools,” said Don Milton, an aerosol expert at the University of Maryland.

Most children younger than 12 seem to have only mild symptoms, if any, so elementary schools may get by. “So far, we don’t have evidence that elementary schools will be a problem, but the upper grades, I think, would be more likely to be a problem,” Milton said.

College dorms and classrooms are also cause for concern.

Milton said the government should think of long-term solutions for these problems. Having public schools closed “clogs up the whole economy, and it’s a major vulnerability,” he said.

“Until we understand how this is part of our national defense, and fund it appropriately, we’re going to remain extremely vulnerable to these kinds of biological threats.”

What are some things I can do to minimize the risks?

Do as much as you can outdoors. Despite the many photos of people at beaches, even a somewhat crowded beach, especially on a breezy day, is likely to be safer than a pub or an indoor restaurant with recycled air.

But even outdoors, wear a mask if you are likely to be close to others for an extended period.

When indoors, one simple thing people can do is to “open their windows and doors whenever possible,” Marr said. You can also upgrade the filters in your home air-conditioning systems, or adjust the settings to use more outdoor air rather than recirculated air.

Public buildings and businesses may want to invest in air purifiers and ultraviolet lights that can kill the virus. Despite their reputation, elevators may not be a big risk, Milton said, compared with public bathrooms or offices with stagnant air where you may spend a long time.

If none of those things are possible, try to minimize the time you spend in an indoor space, especially without a mask. The longer you spend inside, the greater the dose of virus you might inhale.

New Delhi/Washington, Feb 14: India has offered to partially open up its poultry and dairy markets in a bid for a limited trade deal during US President Donald Trump's first official visit to the country this month, people familiar with the protracted talks say.

India, the world's largest milk-producing nation, has traditionally restricted dairy imports to protect the livelihoods of 80 million rural households involved in the industry.

But Prime Minister Narendra Modi is trying to pull all the stops for the US President's February 24-25 visit, aimed at rebuilding bonds between the world's largest democracies.

In 2019, President Trump suspended India's special trade designation that dated back to 1970s, after PM Modi put price caps on medical devices, such as cardiac stents and knee implants, and introduced new data localization requirements and e-commerce restrictions.

President Trump's trip to India has raised hopes that he would restore some of the country's US trade preferences, in exchange for tariff reductions and other concessions.

The United States is India's second-largest trade partner after China, and bilateral goods and services trade climbed to a record $142.6 billion in 2018. The United States had a $23.2 billion goods trade deficit in 2019 with India, its 9th largest trading partner in goods.

India has offered to allow imports of US chicken legs, turkey and produce such as blueberries and cherries, government sources said, and has offered to cut tariffs on chicken legs from 100 per cent to 25 per cent. US negotiators want that tariff cut to 10 per cent. The Modi government is also offering to allow some access to India's dairy market, but with a 5 per cent tariff and quotas, the sources said. But dairy imports would need a certificate they are not derived from animals that have consumed feeds that include internal organs, blood meal or tissues of ruminants.

New Delhi has also offered to lower its 50 per cent tariffs on very large motorcycles made by Harley-Davidson, a tax that was a particular irritant for President Trump, who has labelled India the "tariff king." The change would be largely symbolic because few such motorcycles are sold in India.

President Trump will be feted in PM Modi's home state of Gujarat, then hold talks in New Delhi and attend a reception that the hosts have promised will be bigger than the one organised for former president Barack Obama in 2015.

But it is far from clear whether India's offers will be enough to satisfy US Trade Representative Robert Lighthizer, who cancelled plans for a trip to India this week. Instead, he has held telephone talks with Commerce Minister Piyush Goyal.

The US dairy industry remained sceptical on Thursday that a viable deal is at hand.

"We're always looking for market access, but in terms of India, as of today I'm not aware of any real progress going on," said Michael Dykes, president of the International Dairy Foods Association and a member of USTR's agricultural trade policy advisory committee.

Mr Dykes said the US dairy industry was looking for access in viable commercial quantities.

A USTR spokesman and India's trade ministry did not respond to requests for comment.

A parliament panel is reviewing a draft data privacy law that imposes stringent controls over cross-border data flows and gives the government powers to seek user data from companies.

It is not clear whether it will be passed, or in what form, but the possibilities have unnerved US companies and could raise compliance requirements for Google, Amazon.com Inc, and Facebook.

The draft law is not part of the trade discussions, Indian officials say, because the issue is too difficult to resolve at the same time.

"The privacy and localization piece will be raised independently and in concert with the trade discussions," said a Washington-based source with knowledge of the US administration's thinking.

President Trump on Tuesday was non-committal about sealing a trade deal before his visit. "If we can make the right deal, we'll do it," he told reporters.

Two US sources said progress had been made on proposed alterations to the medical device price caps. India's new import tariffs on medical devices, walnuts, toys, electronics and other products on February 1 surprised US negotiators, however.

The new tariffs were aimed at China, which also makes medical devices, according to an Indian government source. "We have to protect our market and our companies," the source said.
