Northeast migrants flee Pune, Bangalore, Chennai

Eminent river engineer and former professor of civil engineering at IIT in the Banaras Hindu University (BHU) Prof. U.K. Choudhary has said that the judicious use of river technology can help resolve the Coronavirus crisis as well as the plight of Ganga river.

Choudhary, who is also founder of Ganga Research Centre at IIT (BHU), said: "The Ganga water contains a significantly higher proportion of bacteriophages - a kind of virus that kill bacteria. Our ancient scriptures like Vedas, Puranas and Upanishads say that Ganga jal is medicinal water. Scientists later found that Ganga water has bacteriophages capable of killing pathogens."

Explaining further, he said, "Let us analyze the source of bacteriophages. If we take three rivers of Himalayan origin having sources at different heights -the Ganga (Gomukh), Yamuna (Yamunotri) and the Sone river, we find the colours of waters are different. The whitish colour of Ganga water, greenish colour of Yamuna water and the brownish colour of Sone water is also indicative. As Gomukh is the highest among the three, its water comes from lowest depth of aquifer as compared to Yamunotri and Sone river," he explained.

Thus, the quality of river water is proportional to height of origin point. This defines the genetic character of Ganga water. The balanced flow of this water in entire length of the Ganga defines the medicinal property of Ganga water," he stated.

Prof Chaudhary said that the bacteriophages in the Ganga can curb the spread of coronavirus through soil, water and air.
He suggested that the idea is to preserve the medicinal value of Ganga water and to use it to fight Corona. He said that this can be done by opening the gates of all the dams and barrages in a way that the discharge through each is similar to the water at Gomukh. In this way, the concentration of bacteriophage will be enhanced in Ganga water making it more effective against pathogens.

"With increasing diffusion of bacteriophages in water and soil, the spread of Coronavirus will be impacted and reduced. This methodology and technique can also help maintain the quality of Ganga water later when the problem of Corona ends," he said.

New Delhi, Jun 13: Veteran Urdu poet Anand Mohan Zutshi 'Gulzar' Dehlvi passed away on Friday afternoon, five days after he recovered from COVID-19.

He died at his Noida home, and was a month shy of turning 94.

"His corona test came negative on June 7 and we brought him home. Today he had lunch and at around 2.30pm he passed away," his son Anoop Zutshi told PTI.

"He was quite old, and the infection had left him very weak. So doctors are thinking it was possible a cardiac arrest," he added.

A freedom fighter and a premier 'inquilabi' poet, Dehlvi was admitted to a private hospital on June 1 after testing positive for coronavirus.

Born in old Delhi's Gali Kashmeerian in 1926, he was also the editor of 'Science ki Duniya', the first Urdu science magazine published by the Government of India in 1975.

Remembering her fond memories of Dehlvi, historian-writer Rana Safvi recalled seeing the poet at most 'mushairas' in Delhi.

"I cannot express how big a loss it is. We used to see him at every 'mushaira' in Delhi. It's a big loss to Delhi and the world of poetry," Safvi said.

She also took to Twitter to express her condolences.

"Sad to hear about Gulzar Dehlvi saheb's demise. He was the quintessential Dilli waala. May he rest in peace," she tweeted.

According to Delhi-based poet and lawyer Saif Mahmood, Dehlvi was "the presiding bard of Delhi", following in the footsteps of iconic poets like Mirza Ghalib, and Mir Taqi Mir.

His death is the "end of an era", he said.

"No one knew the nooks and crannies of Mir and Ghalib's Delhi like him. Gulzar saheb claimed that his father, Allama Pandit Tribhuvan Nath Zutshi 'Zaar Dehlvi', was a disciple of the renowned poet Daagh Dehlvi," he said, while reminiscing his meeting with Dehlvi three years back.

The poet had recited a still unpublished 'sher' (couplet) then, Mahmood said, which seems more relevant now in the aftermath of his demise.

"Mere baad aane waalon, meri baat yaad rakhna/ mere naqsh-e-pa se behtar, koi raasta nahin hai". (Those who come after, remember what I say/ there’s no better way than to follow my footprints).

"He was a true exemplar of not just the Urdu language but also of the Urdu culture. In fact he was a living and breathing form of Urdu tehzeeb," Mahmood said.

New Delhi, Apr 15: As the world grapples with coronavirus, researchers have found the presence of a different kind of coronavirus -- bat coronavirus (BtCoV) --in two bat species from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu, according to a study by the Indian Council of Medical Research (ICMR).

There is no evidence or research to claim that these bat coronaviruses can cause disease in humans, said Dr Pragya D Yadav, Scientist at the National Institute of Virology (NIV), Pune and also the first author of study.

The study has been published in the Indian Journal of Medical Research,

Twenty-five bats of Rousettus and Pteropus species from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu were found positive for BtCoV in Kerala, Himachal Pradesh, Puducherry and Tamil Nadu.

"These bat coronaviruses have no relation with SARS-CoV2 responsible for the COVID-19 pandemic," Yadav said, adding that Pteropus bat species were earlier found positive for Nipah virus in 2018 and 2019 in Kerala.

"Bats are considered to be the natural reservoir for many viruses, of which some are potential human pathogens. In India, an association of Pteropus medius bats with the Nipah virus was reported in the past. It is suspected that the recently emerged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) also has its association with bats," the objective of the study titled 'Detection of coronaviruses in Pteropus and Rousettus species of bats from different states of India' stated.

"In the present scenario of changing demography and ecological manipulations, it is challenging to have checks on the encounters of bats with other animals and humans," the study stated, highlighting that the need for active and continuous surveillance remains crucial for outbreak alerts for bat-associated viral agents with epidemic potential, which would be helpful in timely interventions.

"Although CoVs in the subfamily coronavirinae do not usually produce clinical symptoms in their natural hosts (bats), accidental transmission of these viruses to humans and other animals may result in respiratory, enteric, hepatic or neurologic diseases of variable severity. It is still not understood as to why only certain CoVs can infect people," the study said.

The scientists stressed on the need of proactive surveillance of zoonotic infections in bats.

The detection and identification of such viruses from bats also recommends cross-sectional antibody surveys (human and domestic animals) in localities where the viruses have been detected.

Similarly, if the epidemiological situation demands, evidence-based surveillance should also be conducted, the study said while emphasing on the need of developing strong mechanisms for working jointly with various stakeholders such as wildlife, poultry, animal husbandry and human health departments.

"In conclusion, our study showed detection of bat CoVs in two species of Indian bats. Continuous active surveillance is required to identify the emerging novel viruses with epidemic potential," Dr Yadav said.

Elaborating on the study, Dr Yadav said throat and rectal swab samples of two bat species -- Rousettus and Pteropus -- from seven states were screened for the bat coronvirus during which the representative samples collected from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu tested positive while those from Karnataka, Chandigarh, Punjab, Telengana, Gujarat and Odisha came out negative.

The reverse-transcription polymerase chain reaction (RT-PCR) tests and sequencing were used for the confirmation of the findings.

"This is an ongoing study to understand the prevalence of the Nipah virus in bats," she said.
