Hinduism allows Hadiya’s father to kill her and go to jail: Saffron leader

Bengaluru, May 19: Containment zones in Karnataka will be much smaller in size under the latest lockdown norms. However, rules and loopholes will be tightened and action against violators will be stringent in order to check the spread of the disease.

Revised guidelines issued by the Centre to the state, reveal containment zones are delineated based on mapping of cases and contacts. Intensive action will be carried out in these areas with the aim of breaking the chain of transmission. Therefore, the area of a containment zone should be appropriately defined by the district administration/local urban bodies with technical inputs at local level.

The health department is considering shrinking the size of containment zones from the existing 100 metres to open up more space for economic activities. Medical education minister K Sudhakar, also a member of the Covid taskforce, said additional chief secretary (health department) Javed Akthar will issue a new definition of a containment zone after the Covid-19 taskforce holds its next meeting.

“We are planning to further shrink it and restrict containment zones to an apartment complex, independent house or even a lane where the Covid-19 patient resides,” Sudhakar said. He went on to say bigger containment zones will impede businesses and normal activities in the vicinity, something which the government wants to avoid.

The minister said Karnataka will also do away with colour-coding districts. “With restrictions being relaxed for almost all activities, it does not make sense to pursue with colour codes. It is either containment zone or outside containment zone,” he said.

In rural areas, the minister said containment zones will be identified by the taluk heads. Government sources say it is difficult to restrict activities to certain areas or smaller location in rural areas as farmers and people will have to travel to the outskirts of their villages for their livelihood.

An official said, a containment operation (large outbreak or cluster) is deemed successful when no case is reported in 28 days from the containment zone.

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

Washington, Feb 22: US President Donald Trump will raise the issue of religious freedom with Prime Minister Narendra Modi during his visit to India next week, the White House said on Friday, noting that the US has great respect for India's democratic traditions and institutions.

"President Trump will talk about our shared tradition of democracy and religious freedom both in his public remarks and then certainly in private. He will raise these issues, particularly the religious freedom issue, which is extremely important to this administration," a senior official told reporters in a conference call.

The official was responding to a question on whether the president was planning to speak to Modi on the Citizenship (Amendment) Act or the National Register of Citizens.

"We do have this shared commitment to upholding our universal values, the rule of law. We have great respect for India's democratic traditions and institutions, and we will continue to encourage India to uphold those traditions," the official said, requesting anonymity.

"And we are concerned with some of the issues that you have raised," the senior administration official said, in response to the question on CAA and NRC.

"I think the President will talk about these issues in his meetings with Prime Minister Modi and note that the world is looking to India to continue to uphold its democratic traditions, respect for religious minorities," the official said.

"Of course, it's in the Indian constitution -- religious freedom, respect for religious minorities, and equal treatment of all religions. So this is something that is important to the president and I'm sure it will come up," said the official.

Pointing out that India has a strong democratic foundation, the official said India is a country rich in religious, linguistic, and cultural diversity.

"In fact, it's the birthplace of four major world religions," the official noted.
