Clouds do prevent radars from detecting accurately: Air Marshal Raghunath Nambiar

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.

New Delhi, Jun 3: Over 1 lakh scanned copies of Indians' national IDs, including Aadhaar, PAN card and passport, have been put on dark web for sale, cyber intelligence firm Cyble said on Wednesday.

The leaked data seems to have originated from a third party and not from the government system, according to a report by Cyble.

"We came across a non-reputed actor who is currently selling over 1 lakh Indian National IDs on the dark net. With such a low reputation, ideally, we would have skipped this; however, the samples shared by the actor intrigued our interest -- and also the volume. The actor is alleged to have access to over 1 lakh IDs from different places in India," Cyble said.

The personal data leaked by cyber criminals leads to various nefarious activities such as identity thefts, scams, and corporate espionage. Many criminals use the personal details in the IDs to win trust of the people over a phone call for fraudulent activities.

The Cyble researchers acquired around 1,000 IDs from the seller and confirmed that the scanned IDs belong to Indians.

"Preliminary analysis suggests that the data originated from a third party, and no indication or artefact is indicating that it came from a government system. At this point, Cyble researchers are still investigating this further -- we are hoping to share an update soon," Cyble said.

The scanned ID documents indicate that the data may have been leaked from a company's data base in the segment where they have to comply with 'Know Your Customer' (KYC) norms.

"Cyble researchers have also learned about a surge in KYC and banking scams -- leaks such as this are often used by scammers to target individuals, especially elderlies," Cyble said.

The cyber intelligence firm has recommended people to refrain from sharing personal information especially financial information over phone, e-mail or SMS.

"Regularly monitor your financial transaction, if you notice any suspicious transaction, contact your bank immediately," the company said.

In May, Cyble showed two instances where personal data of 7.65 crore Indians have been put on sale in the dark web. In one instance, the seller claimed to have sourced data of 4.75 crore Indians from online directory Truecaller and in other, the seller claimed to have sourced from job websites.

Truecaller, however, had denied the claim of breach in its database.

Thiruvananthapuram, Mar 31: Kerala reported its second COVID-19 death after a 68-year-old man being treated for the virus, died at the Government Medical College Hospital here in the early hours on Tuesday.

The victim, Abdul Aziz, a retired ASI hailing from Pothencode here, was admitted to the isolation ward on March 23 with the symptoms of the Corona infection. He was also suffering from lung and kidney diseases.

Though his first test result for COVID-19 turned negative, the second test result confirmed positive, official sources said.

However, it was not known from where he caught the virus infection. leaving chances for a secondary contract of a COVID-19 patient.

His funeral will take place as per the protocol, the sources added.
