India 6th wealthiest country with total wealth of $8,230 billion: Report

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.

Perambalur, Jan 2: Veteran Tamil writer Nellai Kannan was arrested in Perambalur for criticizing Prime Minister Narendra Modi and Home Minister Amit Shah during a protest against Citizenship (Amendment) Act.

The Tirunelveli Police had registered the FIR against the writer for the speech delivered at a meeting, which was called by the Social Democratic Party of India on December 29 last year.

The police have booked him on the basis of multiple complaints filed by BJP leaders.

Kannan has been booked under Sections 504, 505(1) and 505(2) of the Indian Penal Code.

New Delhi, Apr 23: With an increase of 1,229 new COVID-19 cases in the last 24 hours, the total number of cases reached 21,700, said the Union Ministry of Health and Family Welfare on Thursday.

The tally is inclusive of 16,689 active cases, 4,325 patients have been cured/discharged and migrated, while 686 patients who have died due to the deadly virus.

According to the ministry's data, Maharashtra is on the top of the list with most COVID-19 cases, 5,652 cases of which 789 patients have recovered and 269 patients succumbing to coronavirus.

Gujarat and Delhi are second and third on the list respectively with Gujarat having 2407 cases of which 179 patients have recovered and 103 deaths. Meanwhile, in Delhi, the tally stands at 2248 cases of which 724 patients have recovered and 49 patients have died from COVID-19.

Rajasthan's tally stands at 1,890 cases with 230 patients cured while 27 deaths have been reported as of Thursday.

Madhya Pradesh has 1695 cases of which 148 patients have recovered and 81 deaths reported. Tamil Nadu, on the other hand, stands with 1629 cases of which 662 patients have recovered and 18 have died due to the deadly virus.

Goa has seven cases reported of which all seven patients have recovered from the coronavirus.

Prime Minister Narendra Modi announced on April 14, that the nationwide lockdown would be extended to May 3.
