'Immediate action needed': Naqvi on UP cop's 'Go to Pak' comment

Mar 2: Two more positive cases of the novel coronavirus -- one in Delhi and another in Telangana -were reported, the Union Health Ministry said on Monday.

The person from Delhi had travelled to Italy, it said adding he is being diagnosed at RML hospital.

The other person with the coronavirus infection has a travel history to Dubai, the ministry added.

"Both the patients are stable and being closely monitored," the ministry said.

Sunitha Krishnan is the name of the patient from Telangana and she is a social activist.

Krishnan has tweeted, "So going to enjoy hospitality at Gandhi Hospital for two days as admitted in the isolation ward suspected coronavirus. They have not started the tests yet( 1.30 hrs since I arrived).I believe the results make take 48hrs. At this pace, I have a feeling I am might be here sometime."

New Delhi, Mar 26: Despite repeated assurances by the Centre and state government of no shortage of food and essential services in Delhi, many daily wage earners have started fleeing the national capital on foot to return to their native villages in nearby Uttar Pradesh and other states because of the hardships being faced by them.
Most daily wage earners who are fleeing have complained that they are doing so because they will die of hunger due to lack of resources at their disposal.
"I am going to Azamgarh, my native place which is more than 800 kilometers from here. We have started walking towards our village. On the roads, if we get some vehicles then it will be all right otherwise we will continue on foot. I used to work in the construction sector but all work has stopped, we therefore have no other means to buy our rations. Atleast, food is guaranteed in our homes," Ghanshyam, a daily wage earner, told ANI here.
Rani, another daily wage earner, who was fleeing Delhi along with her family said, "Who would want to leave on foot, but what other options do we have. Our children will die of hunger, even if they are saved from the disease. That is why we are leaving."
While the government has been assuring that it will provide food and other essentials to the low-income groups, the people complained that they are yet to receive any help.
The departing of people has started despite repeated warnings by governments to prevent the influx of persons living in other states to curtail the spread of coronavirus.
Prince, who used to reside in Mongolpuri area of Delhi, said, "If we continue to stay the landlord will pester us for rent. The prices of all commodities are rising with each passing day, this way we will have nothing left to survive. We did not get any help from the government. I am, therefore, returning to Kasganj, which is close to 300 kilometres from Delhi. We will at least get food served twice a day in the village, nobody is offering us even water here."
Earlier on Tuesday, Delhi Chief Minister Arvind Kejriwal had announced Rs 5,000 for each construction worker under Construction Workers Welfare Board Fund.
Addressing a video conference here, he said, "The Delhi government will give Rs 5,000 to each construction worker as their livelihood has been affected due the outbreak of coronavirus."
He also said that the number of night shelters in the city has been increased and more food is being distributed to homeless people.
He also said that due to curfew, several people were not able to get food, and urged the public to send such people to the nearest shelters of the Delhi government, where food was being arranged.

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.
