Huge cache of weapons, steel bombs seized from BJP office in Kannur

Bengaluru, Jul 21: Karnataka Chief Minister B S Yediyurappa on Tuesday said that everyone has to fight COVID-19 while maintaining a stable economy and lockdown is not the solution.

While briefing the media after a meeting with Health Minister B Sriramulu and officials here, CM Yediyurappa said, "There will be no lockdown from tomorrow, people need to get back to work, the economy is also very important. We have to fight COVID-19 while maintaining a stable economy. Lockdown is not the solution, now restrictions will be placed only in containment zones."

"People who came from Maharastra and Tamil Nadu added to the COVID-19 cases in Karnataka. Experts have suggested a 5T strategy - Trace, Track, Test, Treat and Technology. Our COVID warriors are working day and night to safeguard the people of the state, we have to maintain social distance, wear a mask while going out," he added.

CM Yediyurappa further said that more than 80 per cent COVID-19 cases in the state are asymptomatic.

"Five five per cent need ICU or ventilators, 11,230 beds are kept ready for the use of people including private hospitals, medical colleges. The real-time dashboard is ready to serve the people. Now onwards, test report will be given within 24 hours. SSLC exams were conducted successfully. More than 8 lakh students wrote exams in such a situation," he said.

Commenting upon the allegations of COVID-19 mismanagement labelled by opposition leaders, CM Yediyurappa said, "I request all the opposition leaders not to make unnecessary comments. I request Siddaramaiah, D K Shivakumar and others to suggest us valuably to fight corona together."

"We will give all the details which are required to D K Shivakumar, Siddaramaih, H D Kumaraswamy. Not even one-rupee corruption is done in COVID-19 management. We will give you all details. No official misused any funds, being opposition leaders, you have all rights to check documents, we will provide them," he added.

Taking to Twitter, Health Minister B Sriramulu said that the decision to raise the salary of 2,000 AYUSH doctors to Rs 45,000 was taken in the meeting.

"The decision to raise the salary of 2000 AYUSH doctors to Rs 45,000 was taken at a meeting chaired by our Hon. Chief Minister Shri @BSYBJP. Assurance has been given that the demand of private AYUSH doctors too will be reviewed and a decision regarding the same will be taken at the earliest. All doctors who were protesting for the same have withdrawn their resignations and reported to work," he tweeted.

Bengaluru, Mar 3: Karnataka Health Minister B Sriramulu has said that a medical team is monitoring the health condition of all those people who had stayed with the coronavirus-hit techie who is admitted to a hospital in Hyderabad.

The first confirmed case of the novel coronavirus (COVID-19) in Telangana was reported from Hyderabad on Monday where a man from Bengaluru, who recently returned from Dubai, tested positive for the virus.

"It has come to our knowledge that the coronavirus-hit person in Hyderabad had gone from Bengaluru. Therefore, all the members in the house where he had stayed here have been identified and are under watch," Mr Sriramulu tweeted on late Monday night.

The minister said he has convened a meeting with the additional chief secretary, commissioner and other senior officials of the health department today.

"Our government has initiated all the measures to prevent the spread of this virus," the minister said.

It is learnt that the 24-year-old techie had not contracted it when he was in Bengaluru but all precautionary measures have been taken.

The software engineer, who works in Bengaluru, had worked with people from Hong Kong in Dubai last month where he is suspected to have contracted the virus, Telangana health minister E Rajender told reporters in Hyderabad.

The man reached Bengaluru on February 19/20 and later went to Hyderabad in a bus.

He took treatment for fever after coming to Hyderabad and was admitted to a private super speciality hospital in the city. As it did not subside, he came to the state-run Gandhi hospital on Sunday evening, Mr Rajender said.

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.
