Oh My Gau Mata! Modi govt withdraws ban on sale of cattle for slaughter

Bengaluru, Jul 20: Karnataka on Monday reported 3,648 COVID-19 cases taking the tally to 67,420, informed the state health department.

According to a bulletin issued by the department, the state recorded 72 more deaths due to COVID-19 with the toll at 1,403 while six patients who tested positive for the infection have died due to non-COVID causes, as of Monday.

There are 42,216 active cases in the state.
As many as 730 patients were discharged today, taking the total discharged patients to 23,795.
Bengaluru recorded the highest number of cases and deaths today at 1,452 and 31, respectively, informed the state health department.

India's COVID-19 case tally crossed the 11-lakh mark with the highest single-day spike of 40,425 new cases and 681 deaths reported in the last 24 hours, said the Union Health and Family Welfare Ministry on Monday.

The total cases in the country now stand at 1,118,043 while the death toll is 27,497.

The ministry said the total number of cases include 390,459 active cases and 700,087 cured/discharged/migrated.

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.

Bengaluru, Apr 11: Former prime minister H D Deve Gowda claimed the lockdown decision was taken in 'haste' without forethought because of which farmers and the working class were 'suffering' and suggested measures to mitigate the impact. The state government should have consulted experienced citizens, officials, progressive farmers, farmer organisations and wholesale traders about the pros and cons before lockdown, he said in a letter to Chief Minister B S Yediyurappa, while highlighting that 61 per cent of the state's population depended on agriculture.

Because of the "hasty decision taken without any preparations", farmers of the country and the state are facing financial distress," he said in the April 9 letter, a copy of which was released to media here on Friday. The JD(S) patriarch suggested taking up some measures, including ensuring no restrictions on agriculture activities, procurement of horticulture produce at a fair price, relaxing export curbs on it, to provide relief to farmers, agriculture labourers, and daily wage workers.

On Sunday, Gowda had said he has assured Prime Minister Narendra Modi of his support in the nation's battle against COVID-19 pandemic when the latter called him to discuss the situation. In his letter to the chief minister, Gowda said: "...the lockdown implemented to control the spread of coronavirus has led our farmers into despair and put their lives into a burning fire.

This lockdown looks like a decision taken at haste without proper thinking and forethought for our farmers, agriculture labourers, and daily wage workers." He said the lockdown decision was taken after remaining 'quite' for about two months since the first corona infection was reported in the country on January 30. Among the suggestions made by the former prime minister include, procurement of horticulture produce at a fair price like in the case of milk from villages by the government through related organisations like Karnataka Horticulture Federation, HOPCOMS among others.

As horticulture produce was perishable, there should be no restriction on its procurement, transportation and marketing; all processing related activities of horticulture produce should be given relaxation from the lockdown, he said. Gowda also called for relaxation on exports for horticulture produce and its processed items. There should be no restriction on agriculture activities; a national grid has to be set up for marketing of horticulture produce, he said.

If such measures were not taken up immediately, the government will have to pay compensation to farmers for losses. Lack of remedial measures would lead to a shortage of supply, leading to rebellion from the people and may result in farmers' suicides and bringing about a situation that might be more grave than coroanvirus, he said.
