Indian public sector banks had 'worst phase' under Manmohan, Rajan: Sitharaman

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.

Bikaner, Jan 5: A government-run hospital in Bikaner saw the death of at least 162 children, higher than the number of deaths in Kota's JK Lon Hospital in December.

"In December, we received 2,219 children from different hospitals out of which 162 children died in the Intensive Care Unit here. None of them was born at the hospital," said Dr HS Kumar, Principal, Sardar Patel Medical College, PBM Hospital.

He, however, denied any negligence on the part of the hospital and said that all efforts were made to save every single life.

The official said that all the deceased children had taken birth at the Primary Healthcare Centres (PHC) and the Community Health Centres (CHC) and were referred to the PBM Hospital in a critical condition.

"Their condition was critical and they breathed their last during treatment," he said.

At least 110 children have lost their lives at JK Lon government hospital in Kota, Rajasthan.

Jan 1: Two army personnel were killed in a gunfight with heavily-armed Pakistani infiltrators along the Line of Control (LoC) in Jammu and Kashmir's Rajouri district on Wednesday, officials said.

The infiltrators were intercepted in the Khari Thrayat forest when they were trying to sneak into India from Pakistan-occupied Kashmir (PoK), they said.

"Two army soldiers martyred during cordon and search operation in Nowshera sector. The operation is still in progress and further details are awaited," Jammu-based Indian Army Public Relations Officer (PRO) Lt Col Devender Anand said in a statement.

The search operation was launched following information about the movement of suspected terrorists, the officials said.

The infiltrators opened fire on the troops and during a fierce gunfight, the two soldiers were killed, they said.

The officials said a massive operation is on in the area.
