Yes, I kicked elderly man; it's a small incident: BJP MP Radadiya

Bengaluru, May 17: Karnataka Deputy Chief Minister and Transport Minister Laxman Savadi on Sunday wrote to Union Minister Nitin Gadkari requesting to issue new lockdown guidelines including permission to operate public transport and said the lockdown has caused a financial loss of Rs 16,00 crore to all four Karnataka Transport Undertakings.

In view of these problems, the state Transport Minister requested Gadkari to permit the deployment of Non-AC buses on scheduled routes to ensure the adequacy of services.

The four State Transport Undertakings (STUs) in Karnataka which are providing bus-based public transport services within the state and to the neighbouring states are Karnataka State Road Transport Corporation (KSRTC), North West Karnataka Road Transport Corporation (NWKRTC), North Eastern Karnataka Road Transport Corporation (NEKRTC) and Bangalore Metropolitan Transport Corporation (BMTC).

"KSRTC, NWKRTC and NEKRTC operate buses for mofussil services i.e. Interdistrict, intradistrict and interstate, whereas BMTC operates only in urban and suburban areas in the city of Bengaluru. The four STUs put together hold a fleet of about 24,900 buses including 1,520 air-conditioned buses and operate about 71.00 lakh km. per day and carries about 98.00 lakh passengers every single day," Savadi outlined in the letter.

The Minister said due to the COVID-19 outbreak and the lockdown that ensued have brought regular bus operations and functioning to a grinding halt.

"This has caused a devastating impact on the operations of all the four STUs due to the combination of lack of revenue and continuing fixed costs such as salaries and pensions to staff, payables against existing loans etc. It has been estimated that the lockdown has caused a financial loss of INR 1,600/- crore to these four STUs," he added.

Savadi said even after post-COVID lockdown, operations and revenues won't reach its previous demand& supply patterns in the next six to eight months due to reduced economic activity and users' perceived risk of contacting COVID in public transport.

In addition to that, "occupancy should be allowed up to seating capacity (without standees). This is essential to meet minimal demand," he said in the letter.

"The crew should wear facemask and hand gloves. The crew with health issues should not be deployed. The face masks should be made mandatory for all the passengers. Only asymptomatic persons should be allowed to travel in public transport. The Government of India may consider staggering working hours for various sectors to reduce peak hour traffic demand," the minister listed out these recommendations in the letter.

Savadi said that with social distancing norm of reduced seating capacity in public transport, it will not be possible to provide transport facility to all the daily passengers. This will create demand for more buses, which cannot be met.

"Restrictions on public transport will lead to passenger commute by overcrowding in smaller vehicles like cars, maxi cabs, goods tempos etc. which will adversely affect preventive measures," he added.

Therefore, Savadi requested Union Minister to look into the above matter and issue fresh guidelines to all the states / UT's.

Mangaluru, Apr 16: An old refrigerator has been turned into a "disinfection chamber" by researchers who are striving to come up with solutions to tackle the spread of coronavirus.

Dr Arun M Isloor, head of Chemistry Department, National Institute of Technology Karnataka (NITK), Surathkal, along with research scholar Syed Ibrahim has come up with the device which can disinfect items kept inside it.

"We have named this as ZERO-COV," Dr Isloor said.

He says the device ensures 99.9 per cent destruction of microorganisms present on the surface of items.

"We can keep items like vegetables, currency notes, books or envelopes inside the chamber. Switching on the chamber for 15 minutes ensures 99.9 per cent destruction of microorganisms present in the surface of the items," Dr Isloor added.

San Diego, Apr 15: Several people lost their sense of smell or taste weeks ago globally and are still waiting for it to come back and now, researchers have identified an association between sensory loss and novel coronavirus 2019 (COVID-19) infection, indicating that loss of smell and taste may be considered as early symptoms of the deadly disease.

Interestingly, the study also found that persons who reported experiencing a sore throat more often tested negative for COVID-19.

The team from University of California-San Diego found high prevalence and unique presentation of certain sensory impairments in patients positive with COVID-19.

Of those who reported a loss of smell and taste, the loss was typically profound, not mild.

"Based on our study, if you have smell and taste loss, you are more than 10 times more likely to have COVID-19 infection than other causes of infection. The most common first sign of a COVID-19 infection remains fever, but fatigue and loss of smell and taste follow as other very common initial symptoms," explained study researcher Carol Yan from UC San Diego.

"We know COVID-19 is an extremely contagious virus. This study supports the need to be aware of smell and taste loss as early signs of COVID-19," Yan added.

For the findings, published in the journal International Forum of Allergy and Rhinology, the research team surveyed 1,480 patients with flu-like symptoms and concerns regarding potential COVID-19 infection who underwent testing at UC San Diego Health from March 3 through March 29, 2020.

Within that total, 102 patients tested positive for the virus and 1,378 tested negatives. The study included responses from 59 COVID-19-positive patients and 203 COVID-19-negative patients.

Encouragingly, the rate of recovery of smell and taste was high and occurred usually within two to four weeks of infection.

"Our study not only showed that the high incidence of smell and taste is specific to COVID-19 infection but we fortunately also found that for the majority of people sensory recovery was generally rapid," said Yan.

"Among the COVID-19 patients with smell loss, more than 70 per cent had reported improvement of smell at the time of the survey and of those who hadn't reported improvement, many had only been diagnosed recently," she added.

Sensory return typically matched the timing of disease recovery.

In an effort to decrease the risk of virus transmission, UC San Diego Health now includes loss of smell and taste as a screening requirement for visitors and staff, as well as a marker for testing patients who may be positive for the virus.

"It is our hope that with these findings other institutions will follow suit and not only list smell and taste loss as a symptom of COVID-19, but use it as a screening measure for the virus across the world," Yan said.
