Karnataka will urge Modi govt to ban SDPI: CT Ravi

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jan 6: The city police commissioner Bhaskar Rao has ordered a special inquiry by the additional commissioner in connection with sexual harassment on a girl hailing from Kasaragod and the allegation that there were attempts to convert her to another religion.

Udupi-Chikmagalur MP Shobha Karandlaje on Sunday met Rao along with the girl and gave a complaint that two youths from Kasargod had raped her and forced her to convert to their religion.

A complaint has been filed in the Kasargod police station, but no action has been taken against them. Since both the accused work in Electronics City police station jurisdiction, she urged the police to arrest them.

Rao said he was yet to gather information about the case and he had directed the additional commissioner to conduct a preliminary investigation and submit a report.

After filing a complaint, Shobha told reporters that she has been sexually harassed ever since she was a minor. 

The MP said that the girl, who was brought from Kasaragod to Electronics City, where the accused youths run a business, was allegedly raped. “I have asked the Police Commissioner to direct the Electronics City police to register an FIR and arrest the youths,” she said.

“I have spoken to the survivor and she said that the youths were also forcing her to convert to Islam and threatened her with dire consequences if she did not,” the MP alleged.

Shobha went on to claim that there was a gang that could be operating to forcibly convert Hindu women to Islam. She also met Chief Minister B S Yediyurappa along with the girl’s family members and gave a petition.

Bengaluru, Jul 2: Karnataka Health Minister B Sriramulu on Thursday launched the ICU Telecard, developed by CISCO to address the concerns of doctors treating coronavirus patients.

Wi-Fi networks and Cisco Health platform help to protect the entire medical team dealing with the infected person by ensuring that doctors do not have to be inside isolation wards and COVID ICUs.

The ICU Telecard has been installed at Victoria and KC General hospital.

"This technology is a necessity to safeguard health of our doctors and it should be implemented in all hospitals. We will discuss about this in the task force meeting and decide regarding the use of this technology in all COVID hospitals in the state. For now, we have installed one at Victoria and KC General hospital" said the minister.

Addressing the complaints of non-release of dead bodies without coronavirus testing, Sriramulu said: "Experts have discussed the same in a meeting with the Chief Minister yesterday, who has ordered for an increase in the number of testing labs. This should resolve the issue. We are also contemplating the conduct of plasma therapy in all districts."

The minister said that the government has also decided to reserve two ambulances for every ward to address the issue of non-availability and will procure more ambulances on rent if the existing ones are insufficient.

He further informed that those who were seen dumping the bodies in a pit in Ballari have been suspended and notice has also been served to officials in Yadagiri.

"We will ensure such instances do not repeat in the state," he said.
