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.

Jammu, Jan 23: The National Investigation Agency (NIA) has brought the disgraced Deputy Superintendent of Police (DSP) Davinder Singh to Jammu for investigations.

According to sources, Davinder Singh has been brought on a transit remand. A formal remand from the NIA court for interrogation will be taken on Thursday.

On Wednesday, fresh raids were carried out by the NIA at Singh's residences in Srinagar.

Singh was caught while transporting two militants, Naveed Babu and Rafi Ahmed, and a lawyer Irfan Ahmed in a vehicle to Jammu on January 11.

According to sources the two militants and the lawyer had plans to travel to Pakistan after reaching Jammu.

The case was transferred to the NIA after initial investigation by the Jammu and Kashmir Police.

Singh has been dismissed from the service and the Jammu and Kashmir administration on Monday forfeited the commendation medal and certificate awarded to him.

Jan 7: India’s monetary authority allowed banks to offer foreign-currency transactions outside of local market hours, a move aimed at boosting trading volumes at home.

Interbank deals, as well as those with customers in and outside India, can be undertaken by banks or their overseas branches and units at all times, the Reserve Bank of India said in a statement late Monday. It stopped short of saying whether the timing of the onshore over-the-counter market has been extended from the current 9 a.m. to 5 p.m.

The move is in line with recent recommendations to reverse the trend of the partially convertible rupee being traded more abroad than in India. London has overtaken Mumbai to become the top center for trading the rupee, adding to a sense of urgency among local authorities to deepen the onshore market.

Average daily volumes for rupee in the U.K. soared to $46.8 billion in April, a more than fivefold jump from $8.8 billion in 2016, according to a survey from the Bank for International Settlements published in September. That exceeded the $34.5 billion recorded in India.

Analysts say more trading abroad could amplify volatility in the domestic market and reduce the effectiveness of policy actions.

India’s decision comes as the London Stock Exchange Group Plc has started asking market participants if they want the bourse to function fewer hours, signaling it’s open to an argument driven by changing trading patterns and calls for a better work-life balance.
