Maya Kodnani was not present in Naroda Gam on day of riots: Amit Shah tells court

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.

Expressing concern over the ban imposed on TikTok by the government of India, Facebook CEO Mark Zuckerberg has reportedly called the development in the south Asian country “worrisome”.

TikTok was amongst the 59 Chinese apps that were banned in India but why it hogs the maximum limelight because TikTok had the second-largest user base in India with over 200 million users.

As per The Verge writer Casey Newton, Zuckerberg was worried about TikTok’s India ban. Although it soon cashed into the opportunity and released a TikTok clone “Reels”, the government’s reason behind banning the app in India wasn’t received well by Mark Zuckerberg. 

He had said that if India can ban a platform with over 200 million users in India without citing concrete reasons, it can also ban Facebook if something goes amiss on the security and privacy front.

Why Mark finds it particularly worrisome because Facebook is already involved in a lot tussle with the governments across the world involving national security concerns. 

“Facebook already faces fights around the world from governments on both the left and the right related to issues that fit under the broad umbrella of national security: election interference, influence campaigns, hate speech, and even just plain-old democratic speech. Zuckerberg knows that the leap from banning TikTok on national security grounds to banning Facebook on national security grounds is more of a short hop,” the report by Casey read.

Facebook till now has not faced any kind of issue in India but considering the debacle with the other governments, it is not entirely wrong to worry about its future in India if any national security issue arises. Back in 2016, Facebook’s Free Basics service, which means a free but restricted internet service, was banned in India by the telecom regulators. 

The TRAI had said that the Free Basic services were banned in India because it violated the principles of net neutrality. With Free Basics services, Facebook had planned to bring more unconnected users online. But since 2016, there has been no major tussle between the Indian government and Zuckerberg due to national security issues.
