Yellow paint must for vehicles carrying school kids, rules AB Ibrahim

Bengaluru, May 17: Karnataka on Sunday extended lockdown for two days until midnight of Tuesday, May 19. Earlier today, Tamil Nadu and Maharashtra extended the lockdown till May 31. The state government said that the guidelines and norms as followed during Coronavirus Lockdown 3 will remain in place till 19th midnight or till further notice.

Meanwhile, the total number of coronavirus cases in Karnataka rose to 1,146 on Saturday. With 37 deaths and 497 discharges, there are 611 active corona cases in the state. 

Out of 54 new cases, twentytwo are from Mandya, ten from Kalaburagi, six from Hassan, four from Dharwad, three each from Yadgir and Kolar, two each from Dakshina Kannada and Shivamogga, and one each from Udupi and Vijayapura.

Bengaluru, Jan 6: Cab aggregators are once again in news for the wrong reasons after an Ola cab driver misbehaved with a 34-year-old woman passenger and even threatened to kill her when she raised an alarm.

But what followed was worse. The woman, a software engineer, immediately called the Ola emergency number following which they asked her to check if the driver was drunk. She later pressed the emergency button on the Ola app but received a message asking her to dial 100. After the aggregator failed to help her, she said she was lucky to be saved by the public.

Reacting to the incident, an Ola spokesperson said, “We regret the unfortunate incident and have immediately terminated the driver-partner from the platform upon receiving the complaint.”

Shruthi G (name changed), an employee at a software company at Bagmane Tech Park in Mahadevapura, booked an Ola cab after her work in the evening of January 3. She booked pick-up stops at two locations as she had to pick her four-year-old daughter from the day-care centre, which is 2 km away from her house.

However, around 6.22 pm, when the cab reached Malleshpalya near Kids Castle, the driver did not stop the vehicle. He asked her to get down at the last drop location. She told him to stop and tried to open the doors but he locked the doors, insisting that she sit in the car. When she resisted, he held her hands and abused her; he even threatened to kill her if she raised an alarm.

The victim said she pressed the emergency button on the app twice but only got a message advising her to call the police.

When she called the Ola emergency number, the person at the other end asked about her condition and to check whether the driver was drunk. They called back after one-and-a-half hours when she was filing a complaint at the police station.

“Ola did not make any efforts to reach out to the police or do anything to track my location and help me in that situation,” she said.

The victim called 100 and the staffer at the control room asked her which area she was in. Since she was familiar with the area, Shruthi was able to give her location.

“First they told me that the area comes under Baiyappanahalli. Later, they said it comes under HAL. Finally, they figured out the location. It took 20 minutes for the police to reach the spot,” she said.

What saved Shruti was her sheer instinct and luck. Alone in the cab, she started raising an alarm. Luckily, commuters in the other vehicles next to the cab noticed her screaming for help and stopped the driver.

“If this is the kind of security Ola provides its customer, it is very questionable,” she said. “If we have to really call the police during an emergency then why they put out the number and emergency button, it’s a waste of time during that crucial situation. If they directly told us to dial 100 during an emergency, it will save time. Lakhs of commuters take Ola cabs thinking it is safe but they have no mechanism to check their drivers and track their customers in danger.”

Baiyappanahalli police said the accused Bhimashankar Malged was arrested and remanded in judicial custody following the complaint.

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study
