Alwar lynching: Cops give clean chit to 6 miscreants named by victim Pehlu Khan

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, Jul 24: India reported the highest single-day spike of 49,310 coronavirus cases on Friday, according to the Union Ministry of Health and Family Welfare.

The total COVID-19 positive cases stand at 12,87,945 including 4,40,135 active cases, 8,17,209 cured/discharged/migrated.
With 740 deaths in the last 24 hours, the cumulative toll reached 30,601.

Maharashtra has reported 3,47,502 coronavirus cases, the highest among states and Union Territories in the country. A total of 1,92,964 cases have been reported from Tamil Nadu till now, while Delhi has recorded 1,27,364 coronavirus cases.

According to the Indian Council of Medical Research (ICMR), 3,52,801 samples were tested for coronavirus on Thursday and overall 1,54,28,170 samples have been tested so far. 

Dirbrugarh, Feb 4: Three persons, including two BJP activists, have been arrested for allegedly attacking the residence of Union minister Rameswar Teli during anti-CAA protests in Assam, police said on Monday.

The house of Teli, Union Minister of State for Food Processing, in Upper Assam's Duliajan town was attacked on December 11 during the statewide stir against the contentious Citizenship (Amendment) Act, 2019.

"Based on CCTV footages, Debajit Hazarika, Vicky Sonar and Arup Kahar were arrested. We had picked them up on Sunday," Dibrugarh Superintendent of Police, Sreejith T told PTI.

A total of 18 persons have been arrested so far for allegedly attacking Teli's house, he said.

"These three persons were also involved in pelting stones on a police party during protests in Duliajan," Sreejith said.

A BJP source confirmed that Debajit Hazarika and Vicky Sonar are party activists.

Family members of the accused have given statements to the police on the arrested persons' alleged role in violence and attacking Teli's house, sources said.

When contacted, Teli said, "I do not know for what reasons they were apprehended. But if police arrested them after proper investigation, then there must be some truth. The trio stays near my house. They always attended my programmes with their families."

A total of 88 people have been arrested so far from Dibrugarh district for their alleged involvement in violence during protests against the Act.
