Take necessary steps to protect Hadiya’s human rights: SHRC to police

Bengaluru, Mar 23: In the wake of the shutdown in several districts of the state to control the COVID-19 spread, Karnataka government on Monday said food would be provided free of cost through Indira Canteen for the poor who depend on daily wages for their livelihood.

The state-sponsored subsidised 'Indira Canteens' as of now serves breakfast at Rs 5 and lunch and dinner at a cost of Rs 10.

"In the interest of the poor, it has been decided to serve free food for poor. Through Indira Canteen, free food will be served for the entire day for the poor," Yediyurappa told reporters.

The Karnataka government has already announced shutdown of all commercial activities, barring essential services, in nine districts where COVID-19 cases have been reported till March 31.

They are: Bengaluru city, Bengaluru Rural, Mangaluru, Mysuru, Kalaburagi, Dharwad, Chikkaballapura, Kodagu and Belagavi.

Dubai, Jul 9: Air India Express has opened ticket bookings for flights from India to the UAE from July 12 to 26. The carrier posted the announcement on its social media pages.

“INDIA to UAE - Flights are open for sale! Bookings could be made through our website (http://airindiaexpress.in), call centre or authorised travel agents. Visit http://blog.airindiaexpress.in for more details,” the budget airline tweeted.

A clause mentioned in the flyer attached to the post added that only UAE residents with permits to return from India can book flights.

Thousands of Indian expats have been waiting to book flights back to the UAE after being stuck home for about four months due to the COVID-19 travel restrictions.

Vande Bharat Mission flights

Under the fourth phase of Vande Bharat Mission, as many as 104 flights will be operating between UAE and India. 

The Air India announced this on Twitter under a post “#FlyAI : Important Information for ICA approved UAE residents who wish to travel to UAE on Vande Bharat Mission flights.”

A flyer attached to the post addressed passengers who wish to travel to UAE on flights being operated under Vande Bharat Mission by Air India and Air India Express in pursuance of agreement between Civil Aviation authorities of India and the UAE.

“AI and AIE operating evacuation flights to Indian citizens from the UAE to India will carry ICA approved UAE residents (returning to the UAE from India) on the outward journey from India to the UAE.”

“On the India-UAE journey, all these flights will carry only those passengers who are destined for the UAE.”

“This arrangement will be operational for a period of 15 days from July 12 to 26,” the airline added.

While most of the Vande Bharat flights are operated by AIE, a few flights from Sharjah are operated by Air India.

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
