Beef shortage in Goa as Karnataka abattoirs refuse meat supply

New Delhi, Jul 24: The Delhi High Court on Friday asked the ICMR to come out with a clarification that mobile number, government-issued identity card, photographs or even a residential proof ought not to be insisted upon for Covid-19 test of mentally ill homeless persons.

According to an Indian Council of Medical Research (ICMR) advisory of June 19, every person who was to be tested for Covid-19 has to provide a government-issued identity proof and should have a valid phone number for tracing and tracking the individual and his/her contacts.

A bench of Chief Justice D N Patel and Justice Prateek Jalan said that ICMR should issue a clarification by way of a circular or an official order that the identity proof, address proof and mobile number are not required for testing mentally ill homeless persons.

The high court said a camp can be organised for testing such persons as is being done across Delhi for others.

"Guidelines have to be given by you (ICMR). You put it in black and white for the states'' benefit. You only need to clarify in two-three lines that mobile number, address proof and identity cards are not required for testing mentally ill homeless persons," it said.

"Use your powers for the public at large. Once you do so (issue the clarification), all states will comply," the bench added.

Additional Solicitor General Chetan Sharma, appearing for ICMR, sought time to take instructions from the government regarding the observations made by the bench.

The high court, thereafter, listed the matter for further hearing on August 7.

The bench was hearing a PIL moved by advocate Gaurav Kumar Bansal seeking directions to ICMR and Delhi government to issue guidelines for Covid-19 testing of mentally ill homeless persons in the national capital.

The high court on July 9 had asked the ICMR to consider the plight of the mentally ill homeless persons and see whether they can be tested without insisting upon a mobile number, government issue identity card and residential address proof.

The bench had said to ICMR that many homeless mentally ill persons are institutionalised or in shelter homes and therefore, traceable, so there was no need for their identity proof or phone numbers to test them for Covid-19.

In response to the court''s query, ICMR has filed an affidavit stating that the purpose behind the submission of government identity card and telephone number was to ensure proper tracking and treatment of positive cases and their contacts as ''Test/Track/Treat'' is the best strategy for control of Covid-19 pandemic. 

It further said that since health was a state subject, the concerned state health authority may consider adopting a suitable protocol to ensure that the strategy of ''Test/Track/Treat'' is followed and the grievance raised in the PIL is also addressed.

ICMR, in its affidavit, has said that it has only advised facilitating contact tracing as well as tracking of the Covid-19 infected patients.

"The modalities regarding the contact tracing as well as tracking of the Covid-19 infected patients completely falls under the domain of IDSP. NCDC and state health authorities. 

"ICMR is a research organization and the contact tracing, as well as tracking of the Covid-19 infected patients, is not under the domain of ICMR," it has said in its affidavit.

Bansal has claimed in his petition that the Delhi government has not taken seriously the lack of guidelines with respect to Covid-19 testing of mentally ill homeless persons.

He has said the high court had on June 9 directed it to address the grievances raised by him in another PIL with regard to mentally ill homeless persons in accordance with law, rules, regulations and government policy.

He said that on June 13 he also sent a representation to the Chief Secretary of Delhi government for providing treatment to mentally ill homeless persons in the national capital who have no residence proof. 

However, nothing was done by the Delhi government, he had told the court.

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

New Delhi, Apr 16: South Delhi District Magistrate Brij Mohan Mishra on Thursday said that the administration is investigating how the pizza delivery boy contracted the coronavirus.

"In the last 15 days, we discovered houses he had delivered food. We contacted people living in 72 houses and they have been asked to stay in-home quarantine. No symptoms have been seen in people related to him. 

Testing of his roommate has been done and his reports are awaited. The rest of the people don't have any symptoms, they have been placed under institutional quarantine. Those in-home quarantines are also asymptomatic," Mishra said.

"Unless a positive case comes, we feel that transmission has not taken place. The boy told us that he was continuously wearing a mask while delivering the food. We are also finding out how he got infected. We are getting the information about the places he visited for delivery. He was tested on the basis of the doctor's advice. Later, he tested positive," he said.

72 families have to stay in home quarantine in the Malviya Nagar area after the delivery boy tested positive for COVID-19 on Wednesday.
Delhi Health Minister Satyendra Jain said that 17 other delivery boys linked with the infected person have also been placed under institutional quarantine.

"A pizza delivery boy has been detected with COVID-19 here. 17 other delivery boys linked with him have been placed under institutional quarantine and 72 people have been placed under home quarantine," Jain said.

Food delivery app Zomato said that the staff of the infected person's restaurant has delivered some orders which were placed on its platform.

"We've been made aware today that a restaurant's employee, who has been recently tested positive for COVID-19, had delivered food in the past to a few customers in the Malviya Nagar area in Delhi. All these customers have already been contacted by the govt authorities... We are not sure whether the rider was infected at the time of delivery," the company said in a statement.

Zomato also claimed that colleagues of the delivery boy have tested negative for COVID-19.
"This restaurant had instructed their riders to wear masks and follow strict hygiene to keep customers safe from any unintended mishap.

All co-workers of the said rider have been tested negative. And as a precaution, the restaurant where this rider worked has suspended operations," read the statement.
