Riyadh: Jamiyyatul Falah hosts JF Coastal Festival-2017

Mumbai, Feb 26: Targetting Shiv Sena's silence over the recent controversial remark by AIMIM leader Waris Pathan, former Maharashtra Chief Minister Devendra Fadnavis on Tuesday said the Uddhav Thackeray-led party might be "wearing bangles" but the BJP was not and knew how to retaliate in the same manner.

"Shiv Sena might be wearing bangles but we are not. If someone says something then he will be given an answer in the same way. BJP has this much power," said Fadnavis while launching a scathing attack on ruling-Shiv Sena in Maharashtra for not taking strict action against Pathan.

Fadnavis was addressing protestors at Azad Maidan where BJP launched a protest against Maharashtra government over issues related to farmers and women.

On February 20, while addressing an anti-CAA rally, at Kalaburagi in Karnataka, Pathan had said, "time has now come for us to unite and achieve freedom. Remember we are 15 crore but can dominate over 100 crores."

"They tell us that we have kept our women in the front - only the lionesses have come out and you are already sweating. You can understand what would happen if all of us come together," he had said.

Facing flak over his remarks Pathan later took back his words and had said he had not targeted any community but had spoken against members of some organisations.

"If any of my words have hurt someone, I take them back as I am a true Indian," Pathan said at a press conference here.

The AIMIM leader said that he was being portrayed as being anti-Indian and anti-Hindu for the past couple of days.

"I want to say that my earlier statement was basically against people who are members of organisations like RSS, BJP, Bajrang Dal, etc. These 100 are those people who want to divide this beautiful nation," he added.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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: The Karnataka government on Friday said returnees from six states with high COVID-19 cases will be kept in institutional quarantine for seven days.

The states are - Maharashtra, Gujarat, Delhi, Tamil Nadu, Rajasthan and Madhya Pradesh.

As per the standard operating procedure released by the government, all people to arrive via rain, air road are expected to quarantine.

After they test negative for the disease in pool testing, they will be sent for home quarantine for another seven days, the government said.

Returnees from other low prevalence states will be asked to follow 14 days of home quarantine, according to the standard operating procedure (SOP) for entry of persons from other states to Karnataka issued by the state health department late on Friday night.

However home quarantine is allowed for pregnant ladies, people above 80 years, patients with comorbidities and children below 10 years of age, along with one attendant after they test negative.

In special cases like businessmen coming for urgent work, the quarantine period will be waived if they furnish a report from an ICMR-approved laboratory showing they tested negative for COVID-19, it said.

However, if they don't have reports, they will have to stay in institutional quarantine and can leave once their results test negative.

In case their stay exceeds 5 days, they will be sent to the fever clinic and get a five-day extension if found asymptomatic.

The report should not be more than two days old from the date of travel.

All Karnataka returnees who entered from 4 May will be tested from 5-7 days from the time of their arrival.

If found COVID-19 negative, they will be sent to home quarantine and will have to follow due precautions, the SOP stated.
