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, May 6: The government on Wednesday said no data or security breach has been identified in Aarogya Setu after an ethical hacker raised concerns about a potential security issue in the app.

The app is the government's mobile application for contact tracing and disseminating medical advisories to users in order to contain the spread of coronavirus.

On Tuesday, a French hacker and cyber security expert Elliot Alderson had claimed that "a security issue has been found" in the app and that "privacy of 90 million Indians is at stake".

Dismissing the claims, the government said "no personal information of any user has been proven to be at risk by this ethical hacker".

"We are continuously testing and upgrading our systems. Team Aarogya Setu assures everyone that no data or security breach has been identified," the government said through the app’s Twitter handle.

The tweet gave point-by-point clarification on the red flags raised by the hacker.

"We discussed with the hacker and were made aware of the following... the app fetches user location on a few occasions," it said, but added that this was by design and is clearly detailed in the privacy policy.

The app fetches users’ location and stores on the server in a secure, encrypted, anonymised manner - at the time of registration, at the time of self assessment, when users submit their contact tracing data voluntary through the app or when it fetches the contact tracing data of users after they have turned COVID-19 positive, it said.

On another issue that users can get COVID-19 stats displayed on the home screen by changing the radius and latitude-longitude using a script, Aarogya Setu said that all this information is already public for all locations and hence does not compromise on any personal or sensitive data.

"We thank the ethical hacker on engaging with us. We encourage any users who identify a vulnerability to inform us immediately...," it said.

Responding to Aarogya Setu's clarification, Alderson tweeted, "I will come back to you tomorrow".

Ayodhya, Jul 23: All 32 accused in the Babri mosque demolition case should be invited to the "bhumi pujan" ceremony for the construction of the Ram temple here and honoured, a Hindutva outfit leader has said.

Hindu Dharma Sena president Santosh Dubey is one of the main accused in the case.

Dubey also insisted that the Shri Ram Janmabhoomi Teertha Kshetra Trust must also invite all the four Shankaracharyas to the ceremony planned on August 5.

Prime Minister Narendra Modi is also likely to attend the event.

"The office bearers of Ram Janmabhoomi Teerth Kshetra must ensure that along with all 32 accused in the Babri mosque demolition case, the families of the kar sevaks who gave their lives in the Ram Temple movement must also be invited to the 'bhumi pujan' ceremony and must be honoured there," Dubey told PTI.

The top court verdict in favour of the Ram temple at the site would not have been possible had the Babri mosque not been demolished, he said.

"If the Trust does not invite the kar sevaks, it will a display of ego and arrogance. Without inviting the kar sevaks who have been accused in Babri mosque demolition and the families of the slain kar sevaks, the 'bhumi pujan' will remain incomplete," Dubey added.

A special CBI court in Lucknow is recording the statements of the 32 Babri demolition accused under section 313 of the CrPC, which enables them to plead their innocence, if they so want.

The court is conducting day-to-day hearings to complete the trial by August 31 as directed by the Supreme Court.

The mosque in Ayodhya was demolished on December 6, 1992 by 'kar sevaks' who claimed that an ancient Ram temple had stood on the same site. Former deputy prime minister L K Advani and BJP leader Murli Manohar Joshi were leading the Ram temple movement at that time.

Srinagar, Mar 7: Two more accused, including a man who allegedly bought chemicals online for making improvised explosive device (IED) to be used in an attack on a convoy of the Central Reserve Police Force (CRPF) in Jammu and Kashmir's Pulwama last year, were arrested by the National Investigation Agency (NIA) on Friday, an official said.

The terror attack left 40 CRPF personnel dead in south Kashmir's Pulwama last year.

Waiz-ul-Islam, 19, from Srinagar and Mohammad Abbass Rather, 32, from Pulwama were arrested by the NIA, taking the number of those arrested in the case in the past week to five.

"During initial interrogation, Islam disclosed that he used his Amazon online shopping account to procure chemicals for making IEDs, batteries and other accessories on the directions of Pakistani Jaish-e-Mohammed (JeM) terrorists," the official said.

He said Islam personally delivered the items to the JeM terrorists after buying them online as a part of the conspiracy to carry out the attack.

"Rather is an old overground worker of the JeM. He has disclosed that he gave shelter at his home to Jaish terrorist and IED expert Mohd Umar after he came to Kashmir in April-May 2018," the official said.

Rather also sheltered other JeM terrorists - suicide bomber Adil Ahmad Dar, Sameer Ahmed Dar and Kamran, a Pakistani -- at his house before the Pulwama attack, the official said.

"He also facilitated safe shelter for the JeM terrorists, including Adil, at the house of accused Tariq Ahmed Shah and his daughter Insha Jan of Hakripora, who were arrested on March 3," the official said.

He said Islam and Rather will be produced before the NIA special court in Jammu on Saturday, while further investigation in the case continues. The NIA took over the case to probe the conspiracy behind the February 14, 2019, attack in Pulwama.

The last video of Adil, which was released by the JeM from Pakistan after the terror attack, was filmed at the home of Tariq Ahmed Shah. On February 28, the NIA achieved a major breakthrough in the case when it arrested 22-year-old Shakir Bashir Magrey, a furniture shop owner and resident of Pulwama.

Magrey had given shelter and other logistical assistance to suicide bomber Adil. He was introduced to Adil in mid-2018 by Pakistani terrorist Mohammad Umar Farooq and he became a full-time OGW of the JeM.

The explosives used in the attack were determined through forensic probe to be ammonium nitrate, nitro-glycerin and RDX. During investigation into the attack, the identity of the suicide bomber to be Adil Ahmad Dar was confirmed through DNA matching with that of his father.

The other key terrorists involved in the attack have been found to be JeM's south Kashmir divisional head Muddasir Ahmad Khan, killed in an operation by the security forces on March 11 last year; Pakistani terrorists Muhammad Umar Farooq and IED expert Kamran, both killed on March 29 last year; the owner of the car Sajjad Ahmad Bhat, a resident of Anantnag who was killed on June 16 last year, and Qari Yassir, JeM's commander for Kashmir who was killed on January 25 this year.
