Fresh violence erupts in Assam, 5 killed; curfew imposed

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.

Kolkata, Jan 12: Prime Minister Narendra Modi on Sunday announced that Kolkata Port Trust will be renamed as Syama Prasad Mukherjee Port.

Addressing the gathering at the inauguration of 150th anniversary celebrations of Kolkata Port Trust, he said: "I announce the renaming of the Kolkata Port Trust to Dr Shyama Prasad Mukherjee Port. He is a living legend who was a leader for development and fought on the forefront for the idea of One Nation, One Constitution."

"This port represents industrial, spiritual and self-sufficiency aspirations of India. Today, when the port is celebrating its 150th anniversary, it is our responsibility to make it a powerful symbol of New India," Modi said.

The Prime Minister said that the Bharatiya Jana Sangh founder had set the stone for industrialization in India. "Chittaranjan Locomotive Factory, Hindustan Aircraft Factory, Damodar Valley Corporation and several others saw active participation from him," he said.

The Prime Minister also felicitated the two oldest pensioners of the Kolkata Port Trust, Nagina Bhagat and Naresh Chandra Chakraborty.

New Delhi, May 23: India will try to restart a good percentage of international passenger flights before August, Civil Aviation Minister Hardeep Singh Puri said on Saturday, three days after announcing resumption of domestic flights from May 25.

All scheduled commercial passenger flights have been suspended in India since March 25 when the Modi government imposed a lockdown to contain the novel coronavirus pandemic.

"I am fully hopeful that before August or September, we will try to start a good percentage of international civil aviation operations, if not complete international operations," Puri said during a Facebook live session.

"I can't put a date on it (restarting international flights). But if somebody says can it be done by August or September, my response is why not earlier depending on what is the situation," he said.
