Mumbai, Mar 28: Doctors in Mumbai have not been spared by the novel coronavirus. As Mumbai’s count for Covid-19 cases went up to 58, an octogenarian doctor from Saifee Hospital passed away on Friday. He was a suspected case of coronavirus with co-morbid conditions like diabetes and had a pacemaker implanted, said a press release from the state health department.

As per a statement from Saifee Hospital, he underwent a CT scan at Saifee Hospital and was diagnosed positive for Covid-19. The surgeon was transferred to the special isolation facility at PD Hinduja Hospital where he subsequently died. Behranwala’s close relatives had come down from England and were under quarantine.

In a statement, Saifee Hospital, where Behranwala underwent CT scan, said, "All containment and surveillance measures have been implemented to ensure the safety of our staff patients and visitors. Saifee Hospital reiterates that the Hospital is fully operational," said Dr Vernon Desa, Director (Medical governance and clinical compliance) Saifee Hospital.

In the second case, an Andheri-based doctor, aged 53, has been tested positive along with his 43-year-old wife and 20-year-old daughter. The family doesn’t have a travel history. The doctor reportedly came in contact with the virus through a patient. MCGM has taken samples of 60 patients who came in contact with the doctor. "As of now, no patient from his contact has tested positive," Assistant Commissioner, Vishwas Mote.

Another doctor who practiced at Vakola tested positive after he came in contact with a person having travel history to Italy, later tested positive. The doctor has been admitted at Raheja hospital and samples of his close contact have been taken.

New Delhi, Feb 20: Hitting out at the Bharatiya Janata Party (BJP), Congress leader Sachin Sawant on Thursday said that the same BJP who tried to pressurise government lawyers so that the accused in the Malegaon bomb blast case, Samjhauta express case can be let off are now demanding that there should be a re-investigation in the 26/11 terror attacks, this is the biggest irony.

"By demanding that the case be re-investigated the BJP which gave a ticket to Pragya Thakur who was accused in the Malegaon blast case, has insulted all those brave police, the army who fought bravely. BJP should apologise to all those people," he said.

"If the BJP were serious about re-investigating the case why didn't they do it when they were in power in the state and the Centre? Was the government sleeping for the last five years? asked Maharashtra Congress committee's general secretary, Sachin Sawant.

"Rather than this, the BJP should ask for a fair inquiry in the incident where a Kashmir police officer Davindar Singh was caught in the company of terrorists and also, the role of the Sangh Parivar in the Malegaon Blasts," said Sawant.

Sawant said that BJP has crossed all limits while lying and it has stooped to the lowest levels of political discourse and is not thinking twice before defaming the Opposition.

In the book written by the retired police officer Rakesh Maria doesn't have anything other than what was there in the charge sheet on Ajmal Kasab. In his confession, Kasab has said that he was given an ID card with a Hindu name and also a red coloured thread by the Lashkar-e-taiba.

Because of this forged identity, they would be able to dodge the police. All these details have been clearly mentioned in the Kasab's confession.

Maria has mentioned in his book that if Kasab was not caught alive, the media would have declared him as a Hindu. Maria hasn't said that there was any kind of government pressure or any other conspiracy behind it. He was only talking about the media and also given all the details in the charge sheet. The BJP is only using this as a political tool in their low-class politics.

The leader added that, "The letter written by BJP MLA Atul Bhatkhalkar to CM Uddhav Thackeray has crossed all limits of lying. The Congress government in Maharashtra had formed a committee under retired home secretary Ram Pradhan to probe the 26/11 attack."

On the basis of an interview given by Ram Pradhan to a national daily on the 10th anniversary of the 26/11, he has levelled baseless allegations on former Central Home minister P Chidambaram, he added.

Bhatkhalkar in his letter has said that Chidambaram had asked Ram Pradhan to not to disclose the local connection that was found in the conspiracy. In fact, there is no such mention in the interview given by Ram Pradhan. Pradhan has said in the interview that Chidambaram wanted to see the report. Hence along with the report, some sensitive information was sent to the department separately and those were overlooked. After some time news related to David Headley had surfaced.

Ram Pradhan committee was not set up by the Centre but was set up by the state government and so it was not mandatory for the Centre to inform Ram Pradhan whether cognisance was taken regarding the sensitive information.

"In was during the Congress government that the first terrorist was caught alive due to the bravery of the police force and after following all the due procedures a verdict to hang him was given," said Sawant..

"Everyone has appreciated India's legal system in which even a terrorist was allowed to give his side," he added.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.
