PM must restore govt credibility, implement reforms: Tata

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.

London, Apr 20 : Embattled liquor baron Vijay Mallya, who is wanted in India on alleged fraud and money laundering charges amounting to an estimated ₹9,000 crore, today lost a High Court appeal in UK against his extradition order to India.

A consortium of Indian public sector banks led by the State Bank of India had sought a bankruptcy order against Mallya as part of efforts to recoup around GBP 1.145 billion of unpaid loans from Mallya.

The 64-year-old former Kingfisher Airlines boss had appealed to the High Court against his extradition to India at a hearing in February this year.

Lord Justice Stephen Irwin and Justice Elisabeth Laing, the two-member bench at the Royal Courts of Justice in London presiding over the appeal, dismissed the appeal in a judgment handed down remotely due to the current coronavirus lockdown.

"We consider that while the scope of the prima facie case found by the SDJ [Senior District Judge] is in some respects wider than that alleged by the Respondent in India [Central Bureau of Investigation (CBI) and Enforcement Directorate (ED)], there is a prima facie case which, in seven important respects, coincides with the allegations in India," the judges ruled.

Earlier this month, the High Court in London had deferred hearings on a plea by the SBI-led consortium of Indian banks, seeking the indebted tycoon to be declared bankrupt to enable them recover their loan from him.

Justice Michael Briggs of the insolvency division of the High Court granted relief to Mallya, ruling that he should be given time till his petitions to the Supreme Court of India and his settlement proposal before the Karnataka High Court be determined, allowing him time to repay his debts to the banks in full.

Kozhikode, Apr 28: The remains of seven people who died in the Gulf countries were airlifted from Dubai by a cargo flight which arrived here Tuesday, ending the uncertainty over bringing back the bodies of those who died following non-Covid-19 reasons.

Airport sources said the flight reached the airport by around noon.

The bodies include natives of Kerala, one each of people from Goa and Sivaganga in Tamil Nadu.

"Karipur in among the few airports where cargo flights are operating in South India.

This is the reason why the bodies of those belonging to Goa and Sivaganga and other parts of Kerala have all been brought here for onward transport to respective destinations by road," an airport official said.

"As per information received from the airport, the bodies are of John Johannan of Kollam, David Shamy of Punnakkal, Kannur, Sathyan of Cheranelloor, Thrissur, O C Mathai and Sijo Joy, both of Pathanamthitta, Sreenivasan of Sivaganga and Henrick D Soza of South Goa," said Thomas, Assistant Sub Inspector, Special Branch CID, Malappuram.

Special passes have been issued to ambulances to transport the bodies to their destinations after the formalities at the airport are over, a senior police officer said.

There had been some confusion on bringing back the bodies from the Gulf region for about a week for want of clearance from the embassy authorities.

Chief Minister Pinarayi Vijayan had written to Prime Minister Narendra Modi last week seeking his intervention in ensuring that bodies of Keralites, who die in Gulf countries due to no non COVID-19 reasons, should be broughtto the state without any delay forenabling family members to perform their last rites.

Vijayan also wanted Modi to direct Indian Embassies to issue necessary clearances without seeking individual approvals from the Ministry of Home Affairs and avoid any delay.

The mortal remains are now being broughtin cargo planes as passenger flights are not being operated due to the COVID-19 lockdown.
