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.

Thiruvananthapuram, Jan 25: Kerala Chief Minister Pinarayi Vijayan on Friday asked the state's MPs to take up the matter of deaths of eight Keralites at a resort in Nepal early this week, with the Centre to pursue the matter with the neighbouring country's government.

He was speaking to the MPs at the customary meeting that the Chief Minister has with all MPs ahead of every session of the parliament.

"The demand has come from the families of the victims for a fair probe on what happened and adequate compensation. For this, you (MPs) should take it up with the Centre. A probe has to be done by the Nepal authorities and the Centre should pursue this with them," Pinarayi reportedly stated. 

"We (the state government) have already taken the issue with the Centre and will now send a detailed letter on the need for a fair probe by the Nepal authorities," he added.

The eight dead include Praveen Krishnan Nair, who worked in the UAE and was on a short vacation here, when the tragedy struck the family. His wife Saranya, a second year M.Pharma student, and their three children, were also killed.

On Friday morning, it was a goodbye that Thiruvananthapuram has perhaps not seen before, as hundreds of people, many of them strangers, came to pay last respects to the five members of the Nair family.

The family of Praveen Nair decided to bury the bodies of the three children and cremate the bodies of Praveen and Saranya. It was also decided to bury the ashes of the couple alongside their three children in the compound of their house.

The second family hailed from Kozhikode and the bodies of Ranjith, an IT professional, his wife, who works in a cooperative bank and their younger child, who slept in the same room as that of Praveen, arrived at the Kozhikode airport on Friday morning.

State Transport Minister A.K. Saseendran and many others were there to receive the bodies, which were first taken to Ranjith's new home that is almost complete.

From there it was taken to a hall for all to pay their last respects and then to the family home of Ranjith where the cremation took place.

Watching everything happening was Ranjith's elder son, seven-year-old Madhav, who escaped that night in Nepal as he was sleeping in another room.

Madhav had arrived from Delhi on Thursday and was unaware of the tragedy as he was busy moving around in a new bicycle, which his relatives had bought to keep him busy.
