Ramesh Jarkiholi did not met Amit Shah, says BJP

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, June 24: Congress leader Ivan D’Souza has vowed to serve the poor and practice as a lawyer in the city, as he completed six years of tenure as a member of Karnataka legislative council on June 23. 

Expressing satisfaction about his work as an MLC, he said: “I’m one among the three MLCs who have 100% attendance in the council. Meanwhile, I’m the only council member to utilise the privilege of raising five questions in each session. I brought several major issues to the government through the questions and succeeded in finding solutions to the problems of people.”

“During my six years of tenure as a council member, I could bring sanctions to the tune of Rs 46 crore through various departments. Meanwhile, financial aid to the tune of Rs 13.24 crore has been distributed through Chief Minister’s Relief Fund to nearly 1,600 beneficiaries. I will continue to serve the poor on my own as an individual. For this, I have set up an office in the premises of my house,” Ivan said, adding that he has distributed grocery kits and other essential items to over 18,000 families during the lockdown period.

“I have successfully fulfilled my duties as the chief whip of the government in the council and also as the parliamentary secretary to revenue department in Siddaramaiah and H D Kumaraswamy governments, respectively,” he said. 

Ivan said his office in the Mangaluru City Corporation (MCC) building will be handed over to JD(S) MLC S L Boje Gowda. “My doors are always open for the people. I will strive to build the party in the state,” he added. 

Bengaluru, Jun 4: The Karnataka government has tweaked quarantine requirements for people arriving from Maharashtra, raising the isolation time from a fortnight to three weeks, an official said on Wednesday.

"Returnees from Maharashtra will be sent to institutional quarantine for seven days, followed by 14 days strict home quarantine, total 21 days," tweeted Health Commissioner Pankaj Kumar Pandey.

The 21-day quarantine regimen is for all asymptomatic people returning from Maharashtra, considering most of the Covid cases in Karnataka are having domestic travel history to that state.

If any of the asymptomatic people develop symptoms during the isolation, they will be subjected to a Covid test.

However, some asymptomatic individuals from Maharashtra have been provided some exceptions from the three-week quarantine and designated as special category passengers.

Special category passengers include people who suffered a death in family, pregnant women, children below 10, elderly people above 60, individuals suffering from serious illness and human distress.

Similarly, the department has also made some provisions for business travellers from Maharashtra.

"To establish that one is a business visitor, (that) person should show confirmed return flight or train ticket which should not be more than seven days later from the date of arrival," ordered Chief Secretary T.M. Vijay Bhaskar.

Similarly, if a business visitor is arriving on road, he should provide the address proof of the person in Karnataka he intends to meet.

Additionally, such a person should also produce a Covid negative test certificate which is not more than two days old.

"One does not have a Covid negative test certificate such a person should go for institutional quarantine for two days within which Covid test should be conducted at his own cost. After the test result is negative, that person is exempted from quarantine," he said.

However, business travellers have been exempted from hand stamping.

Amending the Sunday orders, Bhaskar, has enhanced the quarantine requirements for Maharashtra returnees.

Many conditions for visitors from other states remain mostly unchanged as notified on Sunday.
