Air India posts Rs 4,600 cr operating loss in 2018-19; aims profit this fiscal

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.

Lucknow, May 3:Holding the Tablighi Jamaat responsible for the spread of COVID-19, Uttar Pradesh Chief Minister Yogi Adityanath on Saturday said that being infected with a virus is not a crime but to hide it is definitely a crime.

Speaking at a programme of a news channel, Adityanath said, "The role of Tablighi Jamaat was most condemnable. To get a disease is not a crime but to hide a disease which is infectious is definitely a crime. And this crime has been done by those associated with the Tablighi Jamaat."

"In Uttar Pradesh and other places where the spread of the coronavirus has been seen, Tablighi Jamaat is behind it. Had they not hidden the disease and went about like its carriers, then perhaps we would have controlled the coronavirus outbreak to a large extend," he said.

The chief minister said action would be taken against them for the "crime that they have committed".

A Tablighi Jamaat congregation in Delhi in March turned out to be a major source of COVID-19 cases, with those who attended the meet returned home in different parts of the country after being infected with the deadly virus.

New Delhi, Jun 5: On World Environment Day, Prime Minister Narendra Modi on Friday urged citizens to ensure that the flora and fauna thrive and take a pledge to preserve our planet's rich biodiversity.

"On #WorldEnvironmentDay, we reiterate our pledge to preserve our planet's rich biodiversity. Let us collectively do whatever possible to ensure the flora and fauna with whom we share the Earth thrive. May we leave an even better planet for the coming generations," the Prime Minister tweeted.

He also shared a clip from his last 'Mann Ki Baat' programme where he mentioned about conservation of rainwater and protecting the rich diversity of nature.

"On June 5, the entire world will celebrate 'World Environment Day'. The theme for this year's 'World Environment Day' is bio-diversity. This theme is especially pertinent in the current circumstances. During lockdown in the last few weeks the pace of life may have slowed down a bit but it has also given us an opportunity to introspect upon the rich diversity of nature or biodiversity around us," the Prime Minister had said.

"Much of the avian fauna had sort of disappeared due to sound and air pollution, and now after years people can once again listen to their melodic chirping in their homes," he said.

The Prime Minister also said that water conservation, in particular the conservation of rainwater, is essential and exhorted everyone to strive for saving rainwater in the upcoming monsoons.
