Srinagar, Mar 31: In order to prevent the spread of coronavirus, the Jammu and Kashmir administration on Tuesday declared 20 villages of Kashmir division as 'red zone'.
"20 villages including Parray Mohala Hajin, Chandergeer Hajin, Batagund Hajin in Bandipora district, Gudoora, Chandgam, Pinglena, Parigam, Abhama, Sangerwani and Khaigam in Pulwama district, Waskura in Ganderbal, Sedew, and Ramnagri in Shopian district have been declared as red zones," said Department of Information and Public Relations, J-K, in a tweet.

In Srinagar district, Mehjoor Nagar, Natipora, Lal Bazar, Eidgah and Shalteng villages have been declared as red zones.

"Chadoora in Budgam district of Kashmir division has also been declared as red zone," another tweet said.

The total number of COVID-19 cases in Jammu and Kashmir climbed to 49 after 11 more people tested positive in the Union Territory on Monday. While three of these cases were reported from Jammu region, eight were from the Kashmir division.

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.

New Delhi, Mar 25: The Congress said on Wednesday that it stood with Prime Minister Narendra Modi on his appeal for 21-day lockdown but was "deeply disappointed by the lack of coherent strategy" and demanded that Rs 7,500 should be transferred to every Jan Dhan, PM Kisan and pension account to tide over the nutrition needs for 21-days.
It also demanded that the Public Distribution System (PDS) ration should be given free.
In a series of tweets, Congress Communications in-charge Randeep Singh Surejwala said that the need of the hour was to implement 'Minimum Income Guarantee Scheme' (Nyay) mooted by the Congress and party leader Rahul Gandhi.
"Please transfer Rs 7,500 to every Jan Dhan, PM Kisan, and every pension account to tide over nutrition needs of 21 days and give free PDS ration. We will rise together as a nation and defeat COVID-19. We stand with lockdown but are deeply disappointed by the lack of coherent strategy or a clear 'way ahead' on your part," he said.
Surjewala asked what steps the government took despite an early warning about COVID-19 and sought details about isolation beds and ventilators available to people.
"Dear PM, India will adhere to the lockdown but what steps did the govt take to tackle the corona pandemic despite early warnings in Feb? When will doctors, nurses and health workers have adequate protection? How many 'isolation beds' and ventilators are available and where?" he said.
He asked how daily wagers and labourers will sustain during the 21-day lockdown.
"What's your plan to address the huge issue of bread and butter and livelihood for millions? How will daily wagers, labourers, MGNREGA workers, factory workers, unorganised workers, fishermen, farmers and farm labour sustain for 21 days?" he asked.
Surjewala said the crying need is to arm doctors, nurses and health workers with personal protection equipment and asked: "why are N-95 masks, Hazmat suits not available?"
"In March itself, India needs 7.25 lakh bodysuits, 60 lakh N-95 masks, 1 crore 3 ply masks? When will they be available?" he asked.
Surjewala said that the government banned the export of ventilators, respiratory devices and sanitisers only yesterday on March 24, "84 days after the spread of COVID-19."
"Is this your government's 'Modus operandi' to fight coronavirus? Too little, Too late!," he said.
Noting that two-thirds of the country's population is engaged in agriculture, he said that Prime Minister Modi did not refer to farmers during his address to the nation and demanded a moratorium on farmers' loans.
"Crop is ready for harvest in March itself. How will it be harvested and sold and who will buy at fair price? Indebtedness relief to farmers is the only way forward in these testing times. Please put a moratorium on farmers' loans and recoveries. Please ensure the procurement of crops at MSP. Let's not forget that farmers are the backbone of India's economy," he said.
Surjewala said the Prime Minister gave only four hours to prepare for 21-day lockdown.
"Did you think of over 5 lakh truck drivers, who are now stranded on roads? Did you think of millions of workers, who are stranded in cities away from home without food or money? What should they do," he asked.
