Kejriwal praises Yogendra Yadav, Shazia Ilmi

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.

Kochi, May 5: India has sent three naval ships to evacuate its citizens stranded in the Maldives and UAE due to the COVID-19 pandemic, a defence spokesperson said in the early hours on Tuesday.

INS Jalashwa deployed off Mumbai coast, along with INS Magar, diverted for Maldives on Monday night, he said.

While INS Shardul diverted to Dubai to evacuate the expatriates, the spokesperson added.

The three ships will return to Kochi, he said.

INS Magar and INS Shardul are Southern Naval Command ships, while INS Jalashwa is from Eastern Naval Command.

New Delhi, Jan 18: The Supreme Court Friday refused to entertain a PIL seeking conferment of 'Bharat Ratna' on Mahatma Gandhi saying that people hold the father of the nation in “high esteem”, beyond any formal recognition.

A bench, comprising Chief Justice S A Bobde and justices B R Gavai and Surya Kant, however asked petitioner Anil Dutta Sharma to give representation to the central government in this regard.

“Mahatma Gandhi is the father of nation and people hold him in high esteem, beyond any formal recognition,” the bench said.

The issue of directing the government to award Bharat Ratna to the father of the nation was not a “justiciable issue”, it said.

The bench however said that it agreed with the sentiments of the petitioner for granting official decoration to Mahatma Gandhi.

Disposing of the petition, the top court said, “We will allow you to give a representation to the Centre in this regard.”

Sharma, in his PIL, had sought a direction to the government to give “official decoration” to Mahatma Gandhi to honour him for the contribution to the nation.
