Never ever visited any rowdy’s home; will retire from politics if allegations proven: UT Khader

Bengaluru, Mar 10: A 75-year-old man who arrived in Kalaburagi from Saudi Arabia on February 29 has been admitted to the isolation ward at Gulbarga Institute of Medical Sciences (GIMS) after he showed symptoms of coronavirus. 

His throat swab has been sent to the laboratory of Bengaluru’s Victoria Hospital. The district Health and Family Welfare Department is waiting for the report. 

The aged man who arrived from Saudi Arabia on February 28, was admitted to a private hospital on March 5 following fever and cough. As he showed the symptoms similar to coronavirus, the health of his family members has also been examined by the doctors and a close watch on them is being kept.

Recently, first confirmed positive case was reported from Whitefield in Bengaluru. The state government had also declared holiday for all primary schools in Bengaluru.

Kasaragod, Mar 31: Two more Kasaragod natives lost their lives on Monday due to blockade of the interstate border by Karnataka police in the wake of outbreak of novel coronavirus.

They could not get emergency health care as the Karnataka police stopped the ambulance carrying them to a hospital in Mangaluru at the border.

Another critically-ill person, who was sent back by Manguluru hospital authorities on March 23 for being a Kasaragod native, also died on Monday.

This is the fifth such case in many days.

The deceased are Madhavan, 50, Ayesha, 55 and Aziz Haji, 61 respectively.

All three of them lived near the Karnataka border.

Madhavan, who hailed from Thummanattu in Manjeswaram, died enroute to Kanhangad hospital after being denied entry to cross over to Karnataka. He had an acute bronchial attack.

Udyavar native Ayesha, an asthma patient, was referred to the Mangaluru Hospital by the hospital authorities at Uppali. When the authorities stopped her at the border, she was taken to the Kanhangad hospital. However, she died before reaching the hospital.

Aziz Haji, from Nayabazar Cherugoli MA Cottage at Uppala, was allegedly refused entry into a Manguluru Hospital on March 23 on account of being a Kasaragod native. Haji was a dialysis patient at the hospital. “We were unable to contact his doctor at the time,” his relatives said. Haji, who was on the ventilator, lost his life Monday morning.

One more from Kerala dies as Karnataka police stop ambulance at border
Kunjathoor native Abdul Hameed and Bandwal native Fathima also lost their lives due to the closing of the interstate border.

The district authorities has appealed to the Government to intervene in the matter and influence Karnataka as to lift a ban in crossing over for ambulances carrying critical patients.

The people of Kasaragod are largely dependent on the medical facilities in Mangaluru for critical illness care.

The Kasaragod MP, Rajmohan Unnithan has said he would move the Supreme court against this.

Kerala Chief Minister Pinarayi Vijayan has already taken up the issue with the Centre.

Kerala HC takes up issue with Karnataka AAG

The Kerala High Court on Monday sought the views of the Advocate General of Karnataka on the issue of the government of the neighbouring state blocking its borders with Kerala.

Considering a Public Interest Litigation (PIL) filed by Kerala High Court Advocates Association, seeking a direction for opening the roads, a bench comprising Justices A K Jayasankaran Nambiar and Shaji P Chali requested the Advocate General of Karnataka to join the hearing at 11 am on Tuesday through video conferencing.

The Court orally observed that the blockades erecting embankments on the inter-state roads would affect the people's right to life.

The Karnataka government blocked the state highway with to prevent movement of vehicles carrying essential goods and people seeking emergency treatment at hospitals in the city of Mangalore bordering Kasaragod.

With 97 infected patients, Kasaragod has the largest number of COVID-19 cases in Kerala. 7,437 people are under observation in the district.

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.
