Israel a 'cancerous tumour' established by west, says Iran's Rouhani

New Delhi, Mar 15: Dozens of Hindu activists held a cow urine party in New Delhi on Saturday to protect themselves from the new coronavirus, as countries around the world struggle to control the deadly pandemic.

Members and supporters of the All India Hindu Mahasabha staged fire rituals and drank from earthen cups to fight the Covid-19 virus at the gathering in New Delhi dubbed a "gaumutra (cow urine) party".

"Whoever drinks cow urine will be cured and protected," Hari Shankar Kumar, a volunteer at the event, said as he served the remedy in brown clay cups.

Governments and scientists have said no medicine or vaccine is available to protect or cure people of the infection that has killed more than 5,400 people and infected nearly 150,000 across six continents.

Two people have died in India while more than 80 have fallen ill, and the government has ordered the closure of some land routes into the country and cancelled all visas to stop the spread of the virus in the world's second most populous country.

Members draped in saffron clothes chanted Hindu hymns at the fire ritual as devotees sang paeans for the sacred animal.

"We have gathered here and prayed for world peace and we will make an offering to the corona (virus) to calm it," Chakrapani Maharaj, the group's leader, told reporters before gulping down a cup of urine.

He then offered a glass to a devil-shaped caricature of the virus to "pacify" it.

He urged people to adopt the "tried and tested" practice of drinking cow urine to ward off diseases, and desist from killing animals and eating meat.

"The coronavirus is also a bacteria and cow urine is effective against all forms of bacteria that harm us," claimed Om Prakash, a participant from the neighbouring state of Uttar Pradesh.

One legislator from the BJP last week suggested use of the urine as well as cow dung can cure the coronavirus.

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, Feb 1: Activist Sharjeel Imam's mobile phone and laptop along with some anti-CAA posters have been seized from his house in Bihar's Jehanabad and rented flat in Vasant Kunj, police said on Friday.

Imam was arrested by the Delhi Police's Crime Branch from Jehanabad in a sedition case and he is being questioned by police for his alleged inflammatory speeches in Aligarh and at the Jamia Millia Islamia University here.

During investigation, a laptop and a desktop belonging to Imam were recovered from his rented flat at Vasant Kunj, Deputy Commissioner of Police (Crime) Rajesh Deo said.

His mobile phone was recovered from his house at his native place in Jehanabad's Kako area on the instance of his brother, he said.

Imam had prepared anti-CAA and anti-NRC pamphlets with "misleading and intimidating facts" and then distributed them in various mosques, the copy of which have been recovered, police said.

The shop from where he made photocopies of the pamphlets has also been identified, they added.

Imam was arrested on Tuesday. He was brought to Delhi on Wednesday and produced at the residence of Chief Metropolitan Magistrate Purushottam Pathak in the evening amid tight security after which police were granted his five-day custody.

The PhD scholar at the Jawaharlal Nehru University's Centre for Historical Studies has been booked for sedition and other charges in several states after videos of his alleged inflammatory speeches, made during protests against the Citizenship (Amendment) Act (CAA), were circulated on the social media.

An FIR was registered against Imam by the Delhi Police on January 25 under IPC sections 124A (sedition) and 153A (promoting or attempting to promote disharmony or feelings of enmity on grounds of religion, race, place of birth, residence, language, caste or community or any other ground whatsoever) among others.
