Hate speech: Jagadish Karanth granted interim bail hours after arrest

Mangaluru, July 24: Karnataka's Dakshina Kannada district reported 8 new Covid-19 deaths in the last two days taking the toll to over 100. The district has recorded 107 Covid-19 deaths till now.

Deputy Commissioner Sindhu B Rupesh on Friday said a 44-year-old man from Mangaluru with the symptoms of respiratory failure, ARDS, AKI MODS hypertension, was admitted to a private hospital on July 19 and died on July 22. His throat swab tested positive for Covid-19 on Friday.

Another 56-year-old man from Mangaluru, who died on July 23, was suffering from urinary tract infection, MODS-septic shock, type II diabetes mellitus, hypothyroidism, systematic hypertension and IHD and had tested positive for Covid-19.

Mangaluru saw two more deaths -- a 75-year-old woman suffering from COPD with type 2 respiratory failure and multi-organ dysfunction syndrome with septic shock and a 65-year-old woman, who was suffering from BP and diabetes and admitted to a private hospital on July 13 and died on July 23.

A 61-year-old woman from Puttur, who was suffering from diabetes mellitus and hypertension and was undergoing treatment at a private hospital, died on July 23.

A 67-year-old man from Bhadravathi in Shivamogga, who was admitted to Wenlock Hospital on July 13 and was suffering from pneumonia and respiratory infection, died on July 23. He too tested positive for Covid-19.

Some of the other deaths were those of -- a 42-year-old man from Bantwal suffering from type 1 respiratory failure, urosepsis and uncontrolled type 2 diabetes and a 67-year-old man from Bhadravathi suffering from acute myocardial infarction, uncontrolled type 2 diabetes and systematic hypertension, Both died at private hospitals on July 23.

180 fresh cases

The Covid-19 graph slightly moved downward with the recording of 180 fresh cases, including four police personnel from Puttur police station. Of the positive cases, 56 are the primary contacts of the infected persons, 68 are suffering from Influenza-Like Illness (ILI) and 10 with the symptoms of Severe Acute Respiratory Infection (SARI).

The contacts of 45 persons who tested positive are being traced. One person with international travel history has also tested positive.

A total of 125 persons recovered and were discharged from hospitals, thus taking the tally of the total discharges to 1987.

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.

Shivamogga, Jan 2: A large number of farmers who wanted to stage a demonstration against Prime Minister Narendra Modi protesting the non-implementation of the 'Swaminathan Report' were detained at Bengaluru, Tumakuru and Shivamogga, police said on Thursday.

According to police, the detentions have taken place in certain parts of Tumakuru, near Bengaluru as well as in Shivamogga.

As part of his two-day visit to Karnataka, Modi is scheduled to visit Tumakuru on Thursday to pay his obeisance to the departed seer of Siddaganga Math Shivakumara Swamiji and meet the present pontiff Siddalinga Mahaswamiji.

Later, he would address a mega public meeting where he will give away the Krishi Karman awards.

In the evening he will reach Bengaluru to visit the DRDO facility to dedicate five DRDO Young Scientists Laboratories to the nation.

Pressing implementation of the Swaminathan Report, which recommends a holistic national policy, the farmers under the leadership of Kodihalli Chandrashekar had planned to stage a demonstration at Tumakuru.

Before they could leave for Tumakuru, the police detained them.

According to Chandrashekar, the farmers have been arrested at Nelamangala, Herohalli near Magadi, Kunigal and Koratagere in Tumakuru district and Shivamogga.

Speaking to PTI, Chandrashekar said the BJP has betrayed farmers by not implementing the Swaminathan report.

"The BJP could implement all the agenda such as abrogation of Article 370, paving way for Ram Temple in Ayodhya and various other poll promises but it ignored its promise of implementing the Swaminathan report," the farmer leader said.

Chandrashekar also said he has been detained at a ground on Magadi Road along with two others while farmers who wanted to take part in the protest have been detained in different parts of the state.
