Muslims shouldn’t live in India; they must go to Pak or Bangla: BJP MP

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 23: Karnataka reported 216 covid-19 positive cases in last 24 hours, marking the highest single day spike in the state ever since the first case was detected on 8 March. 187 of these 216 patients have recently returned from Maharashtra.

A 32-year old male resident of Bengaluru died on Saturday making it the 42nd fatality in the state.

The spike on Saturday takes the total number of covid-19 positive closer to the 2,000 mark and the number of active cases to 1,307 in the state, according to the daily health bulletin of the health department.

Yadgir in northern Karnataka recorded 72 cases on Saturday while Raichur recorded 40 cases. Cases in the sugarcane growing region of Mandya continued to rise as 28 people tested positive on Saturday that takes the total number of active cases to 211 as against Bengaluru that has 124.

Gadag registered 15 cases while Bengaluru recorded 4 cases.

Most of those who tested positive on Saturday had returned from other states, especially Maharashtra, one of the worst affected regions in the country.

The spike in cases comes even as the B.S.Yediyurappa-led state government is deliberating further easing of lockdown restrictions post 31 May. The state government has already resumed public bus and train services as well to facilitate inter-district movement of people that has added to fears of spreading the virus from cities to villages where healthcare infrastructure is poor and inadequate.

Karnataka will also see domestic flight arrivals from Monday.

In a statement on Saturday, Bengaluru International Airport said that it introduced ‘Parking-to-Boarding contactless’ journey.

“We have introduced innovative contactless procedures to minimise exposure at the Airport. These enhancements demonstrate our continued commitment to keep our passengers safe in this environment," said Hari Marar, managing director and chief executive of the airport said in a statement on Saturday.

Bengaluru, Jul 25: The Karnataka government on Saturday announced a waiver of crematorium fees for those who succumb to the COVID-19 infection in Bengaluru and said the city civic body would bear the cost.

It said that from now on, families of the COVID deceased need not pay any fees fixed by the city civic body- Bruhat Bengaluru Mahanagara Palike (BBMP)- across 12 electric crematoriums in the city.

"There were reports in the media about difficulties faced in performing the last rites of those who died due to COVID-19 infections. Aimed at resolving those difficulties, certain decisions have been taken," Revenue Minister R Ashoka said.

He told reporters here that BBMP had fixed Rs 250 as the cremation fee, Rs 100 for the ash collection pot and Rs 900 for the bier (bamboo stretcher on which the body is carried), all of which have been waived for COVID deaths.

"So it will be a waiver of Rs 1,250 per cremation. The BBMP will bear this cost," he added.

Ashoka also announced Rs 500 per body incentive for the personnel who conduct the last rites of COVID victims.

"This is in recognition of their services at a time when family members of the deceased are not ready to touch the body and not ready to take the body in some cases," he said.

Noting that the government has identified 23 acres of land at five places around Bengaluru for burial or cremation of COVID victims, Ashoka locals in all these areas are protesting against it.

Appealing to the people for cooperation during these difficult times, he said the government's intention was to ensure respectful burial or cremation for the deceased.

"Obstructing it is not right, it is not Indian tradition," he said.

Pointing out that it takes almost a day's time for a COVID victim's body to be handed over for burial or cremation, he said "scientifically, according to experts and doctors, the virus will not remain alive for more than three hours.

...Also, bodies are either burnt or buried eight feet below. So there will not be any problem for those living in nearby areas and it will not spread infection. Cooperate with humanity," he said.

"These lands identified are for all religions and communities and once the pandemic subsides, can be used for other deaths as well," he said.
