Modi and MIM will finish Congress all over India, says Akbaruddin Owaisi

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 22: JD(S) president HD Kumaraswamy on Wednesday termed the surrender of the accused in the alleged planting of an explosive at Mangalore Airport as another act of a drama and said that the incident should serve as an Eye-opener for the Prime minister Narendra Modi over the prevailing unemployment problem in the country.

Addressing a press conference, the Janta Dal (Secular) leader said that the surrendered man, who had allegedly planted explosive at the airport, was an employed youth and PM needs to address the prevailing unemployment problem in the country.

The former chief minister said that the accused have higher education qualifications and belonged to the Hindu community, disapproving that only people belonging to the Muslim community resort to violence.

Bengaluru, Jul 4: In a heart-wrenching incident, a 65-year-old coronavirus patient at Hanumath Nagar in South Bengaluru died outside his house waiting for an ambulance on Friday evening. The body was kept on the road for more three hours.

The deceased tested positive for coronavirus on Friday and immediately called an ambulance to reach a hospital. However, according to his family members, as he waited for the ambulance for nearly three hours, he collapsed on the road in front of his house complaining of breathlessness and died.

As the body lay unattended on the road, it began to rain heavily. Soon, videos of the body lying on the road in the heavy rain went viral on social media. 

A senior doctor in charge of the division, however, claimed that the ambulance had arrived in less than half an hour but the patient had died before they reached the spot. 

"The patient had given samples on Thursday at KIMS and tested positive on Friday. BBMP officials informed them that they would reach his house. But the man, fearing that he may be stigmatised in the locality, began walking to the corner of the road and collapsed on the street and died," the officer said. 

Another health official from Basavanagudi limits said: "As the ambulance staff do not transport the dead, they informed the hearse van, which was set to arrive in 30 minutes. But due to the sudden rain and heavy traffic ahead of the curfew hours, they were stranded for almost three hours later." The officials also said the deceased had been suffering from cardiac ailments for almost 10 years. 

Regretting the incident, BBMP officials said they were helpless as was an acute shortage of hearse vans. "We were told that there were 20 deaths today and there are only eight hearse vans available. They had to shift this patient after attending to another mortality and were stuck in traffic. By then, due to the fear of infection, nobody attended to the deceased," the officer explained. 

BBMP commissioner B H Anil Kumar said that such incidents should not recur and ordered an investigation and sought a report. "We will ensure that such incidents do not recur," Kumar said.  

Following outrage on social media, a hearse van was summoned and the body was shifted to the Victoria Hospital mortuary as per the protocol. Police have opened a case of unnatural death.
