UP Legislative Council chief’s son strangled to death by MOTHER

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, Jul 25: Congress leader Priyanka Gandhi Vadra on Saturday attacked the Yogi Adityanath government over its handling of the Covid-19 crisis, saying that at a time when there is an "explosive" rise in cases, the state dispensation's "no test is equal to no corona" policy can lead to a "more frightening situation".

In a letter to the Uttar Pradesh chief minister, the Congress general secretary said that the situation is getting serious and the battle against the pandemic cannot be fought just by publicity and managing news.

Priyanka Gandhi said she hopes the chief minister will take "big and effective" steps that will assure people that the government is committed to protect their lives and they will not be left to God for protection.

"By showing the fear of coronavirus, corruption is thriving. If this is not reined in, the battle against coronavirus will turn into a disaster," Priyanka Gandhi said.

Noting that 2,500 cases of coronavirus were reported in UP on Friday, she said almost all the metros were flooded with Covid-19 cases, but now even the villages were not unaffected by its spread.

"Quarantine centres in UP are in a pathetic state. In some places, the situation is so bad, that people are fearing mismanagement more than the coronavirus. Because of such a scenario, they are not stepping out of their homes for getting tested," Priyanka Gandhi said.

"This is a major failure of the government," she asserted.

The state government by believing in the "no test = no corona" mantra has adopted a low testing policy, she alleged in the letter written in Hindi.

"There is an explosive rise in Covid-19 cases. Till testing will not be increased in a transparent manner, the fight against the pandemic will be incomplete and the situation can become more frightening," she said.

"Your government claimed that there is provision for 1.5 lakh beds, but with only about 20,000 active infected cases, there is a scampering for beds," she said.

If there is a huge crowd in front of the hospitals, then why is the UP government not constructing temporary hospitals on the lines of those set up in Mumbai and Delhi, Priyanka Gandhi asked.

Availing medical facility is the fundamental right of every citizen, she asserted.

"The prime minister is a Member of Parliament from Varanasi, the defence minister is from Lucknow, many other Union ministers are from UP. Why can't temporary hospitals be opened in Varanasi, Lucknow, Agra etc." Priyanka Gandhi asked.

She suggested that temporary hospitals can be operated by the Defence Research and Development Organisation (DRDO), the Army and the paramilitary, or if need be, the DRDO hospital can be brought to Lucknow.

Also, central facilities set up in Delhi can also be used for border districts, Priyanka Gandhi said, adding that their utilisation is not being maximised there.

Noting that home isolation was a good step, she said it should not be implemented in haste.

Informed decisions should be taken on key matters related to home isolation like what will be the arrangement for monitoring patients, who needs to be informed if the patient's condition worsens and what will the medical facilities cost in home isolation, she said.

What will be the arrangement for checking the temperature and oxygen level of the patients in home isolation, she further asked in the letter.

The government should do a complete mapping of it and give complete information at the local level to the public, Priyanka Gandhi said.

The Congress general secretary said that she realises, that often the state government feels that the Congress' suggestions are given only from a political point of view.

"This was evident from the response of your government while we were trying to get buses for UP workers who were walking home," she said.

"I want to assure you once again that protecting the health and life of the people of Uttar Pradesh is our biggest sentiment at this time. We are continuously striving with constructive support and a spirit of service," she said in the letter.

At this time when the pandemic is growing rapidly, the Congress stands with the people of UP and is ready to give full support to the state government, she said.

Tightening its grip over Uttar Pradesh, Covid-19 claimed a record 50 lives in the state on Friday as the deadly virus infected 2,667 people more in the largest single-day spike till date.

Kanpur, Jul 10: Kanpur encounter main accused Vikas Dubey, who was injured in an encounter with the police, died on Friday, the police said.

"Gangster Vikas Dubey arrested for killing eight policemen is dead," confirmed the police.

According to SP Kanpur West Anil Kumar, gangster Vikas Dubey attempted to flee after the car overturned. Dubey attempted to flee by snatching pistol of the injured policemen. However, he was shot in the retaliatory firing.

"Vikas Dubey attempted to flee by snatching pistol of the injured policemen after the car overturned. Police tried to make him surrender, during which he fired at the policemen. He was injured in retaliatory firing by police. He was later rushed to the hospital," SP Kanpur West told reporters here.

Dubey, the main accused in the Kanpur encounter was arrested by the police in Ujjain on Thursday morning. He was on the run for the last six days and had come to Ujjain to offer prayers at Temple, where he was identified by a security guard at the shrine.

The gangster is the main accused in the encounter that took place in Bikru village in Chaubeypur area of Kanpur last week, in which a group of assailants allegedly opened fire on a police team, which had gone to arrest Dubey. Eight police personnel were killed in the encounter.

Dubey managed to escape after the killing.  The Uttar Pradesh police launched a hunt for him and raised the bounty on him to Rs 5 lakh.

Bahua Dubey and Prabhat Mishra, close aides of the main accused, were killed in separate encounters in Etawah and Kanpur respectively, on Thursday.

The main accused's other aide Shyamu Bajpai was arrested by the Chaubeypur police following an encounter. He carried a reward of Rs 25,000, the police informed on Wednesday. Earlier the same day, Uttar Pradesh's Special Task Force (STF) gunned down Vikas Dubey's close aide Amar Dubey in Hamirpur district.
