Mangaluru: Youth turns crime fighter, catches chain snatcher after chase

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, May 7: Fear and anxiety gripped migrant workers who lined up at police stations in the city on Wednesday to register for train services without knowing that the state government had cancelled the train facility.

Senior officials in South Western Railway said they were ready to run special trains for migrant workers. On Tuesday evening, the state government decided to withdraw the requests made for 13 such trains to north India after realtors said they need the labourers here.

Migrants continued to stream into the railway station at Majestic, Bangalore International Exhibition Centre and even the bus station hoping for some travel arrangement. Many who were aware of the government web portal, stood in front of the BBMP ward office or police stations for enrolment.

In Varthur, over 100 migrants stood in front of the police station and sought to know what happened to the forms they had submitted four days ago. "We first went to the BBMP office and were shooed away by an official who directed us to go to the police station. We want to go home and demanded that the police help us. There was no response first. Then they came out and beat us," said Pintu Kumar from Mohanpur of Bhagalpur district in Bihar.

Though a video clip accidentally shot by Kumar showed two police personnel charging the cane at them, a police officer from the Varthur station, however, disputed the claim. "The video doesn’t show the cane landing on any person. We were beating the seat and tyre of two-wheelers to send the migrants away," he said.

At Mahadevapura, the workers came in groups and submitted the forms at the police station.

At the railway station in Majestic, a group of labourers from Bihar, Uttar Pradesh and Jharkhand had walked from several areas in south Bengaluru only to be told that there is no train. Mahendra, a labourer from Jharkhand, said they received 5 kg rice and nothing else in the last 45 days. "Now, I don’t want food. I don’t want the job or money. I can't get stuck here. I want to go home,” he said.

'Restore dignity'

Activists and leaders wrote an open letter to Chief Minister B S Yediyurappa questioning the decision to cancel trains without consulting labourers and protesting the violation of their fundamental rights.

The letter had support of 522 organisations and individuals, including Dalit rights organisations and trade unions. It urged the government to restore the dignity of the migrant workers. "We demand recognition of the autonomy and dignity of the migrant workers to decide their travel plans. No one should be forced either to stay back or to return to their home states," it said.

Bengaluru, Apr 20: As many as 59 people were arrested on Monday for attacking police and health officials at the minority dominated Padarayanapura in the city when they went to quarantine some people, police said.

"Fifty-nine people have been arrested (in Padarayanapura) and have been taken into custody. The people attacked the officials who had gone to quarantine some poeple who were the primary and secondary contacts of three COVID-19 patients," a police officer said.

A large number of people, mostly youth from the minority community poured on to the road on Sunday and thrashed the health workers who had gone to quarantine some people who were the primary and secondary contacts of the health workers.

The officials were allegedly beaten black and blue.

Some local residents who went to the rescue of these officials were also thrashed.

According to police, one among the arrested is a woman by name Firoza who had allegedly instigated the mob to attack the health and police officials.

Subsequently, a large number of police personnel were deployed in the area to avert any untoward incident and to quarantine those who are suspected to be infected with COVID- 19.

Blowing sirens, a strong contingent of policemen carried out a flag march in the area.

The Bengaluru police commissioner Bhaskar Rao later called on Chief Minister B S Yediyurappa and briefed him about the situation in Padayarayanapura.

The violent incident drew angry reactions from various quarters.

Karnataka Home Minister Basavaraj Bommai said an incident like the one at Padayarayanapura will not be tolerated.

"I met Chief Minister and briefed him about the incident. He has told us to act strictly. I have told the same to my officials. We won't tolerate such acts by anyone. We have arrested 59 people. Five FIRs have been registered," the minister told reporters.

Bommai, who visited the area took the senior police officials to task for not being present on the spot when the incident took place.

"Where were you? What were you doing when the incident happened?" he questioned a senior police officer.

"We will demonstrate to the people what is containment zone, what is seal down and what is police action," he said.

Condemning the incident, Health Minister B Srimulu warned those who indulged in such activities.

"The inhuman act of attacking police and health workers in Padarayanapura is highly deplorable. Our government will take appropriate step against those indulging in the attack on health officials and police officials who had gone there to protect them," he tweeted.

BJP's firebrand MP Shobha Karandlaje reacted sharply.

"Seculars attack #CoronaWarriors when they were quarantining the secondary contacts of #Covid19 in Padarayanapura of BLR. While #HealthcareHeroes are working overnight to contain #CoronaPandemic, these morons are assaulting our heroes! Let's not be soft on these anti- nationals!" Karandlaje tweeted.

Meanwhile, the minority leaders called on Congress state president D K Shivakumar to persuade the people of the minority community to assist in identifying the COVID-19 patients or carriers.

Former chief minister H D Kumaraswamy too condemned the attack and demanded stringent action against the culprits.

The Congress MLA from the area B Z Zameer Ahmed Khan while condemning the incident, sought to know why the health workers and police officials went to the area late in the night and not in the morning.

"Why did the police and the health workers go in the night when I had told the BBMP Commissioner that I will take them at 10 am?" Khan told reporters.

Defending those who attacked the government officials, Khan said they were uneducated labourers who didn't know what they were doing.

Padarayanapura and Bapuji Nagar were among the first areas to be completely sealed as people were not abiding by the prohibitory orders under Section 144 of the CrPC.
