Political design behind Jamia, Shaheen Bagh protests to ruin nation's harmony: PM Modi

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, Mar 5: The primary classes of all schools in the national capital will remain closed till March 31 to prevent a possibility of spread of coronavirus, Deputy Chief Minister Manish Sisodia announced on Thursday.

According to Directorate of Education (DoE) officials, while elaborate guidelines have been issued about preventive measures for coronavirus, students of nursery and primary classes are too young to understand the risk, making them more prone to infectious diseases.

Sisodia, who also holds the education portfolio, tweeted, "As a precautionary measure to prevent the possibility of spread of COVID-19 amongst our children, Delhi Government has directed the immediate closure of all primary schools (Govt/ aided/ private/MCD/NDMC) till 31/3/20(sic)."

A senior DoE official said, "Elaborate guidelines have already been issued. However, students of nursery and primary classes are too young to understand the risks associated with COVID-19. Thus they are more prone to infectious diseases and mingle around with classmates more often."

"It will be good if they are trained in the do's and dont's under the care and supervision of their parents at home. However, students of classes other than primary will continue to come to schools or examination centres for writing their examination as per schedule. The teaching, as well as non-teaching staff, will also attend regular school," the official said.

As of now, the number of confirmed COVID-19 cases in the country stands at 30, including 16 Italian tourists. The figure includes the first three cases reported from Kerala last month who have already been discharged following recovery.

Alerted by the coronavirus case reported in Delhi-NCR, schools in the region have sent out advisories to parents suggesting that they do not send their wards to attend classes even in case of mild cough or cold, and saying that they may declare holidays if the need arises. A few schools have announced already holidays and others have advanced their spring break.
