The identification of conceivably pathogenic coronavirus in Indian bats anxieties the requirement for upgrading screening for novel infections in them, as per an examination by the Indian Council of Medical Research (ICMR).
This study was a step towards understanding the coronavirus circulation in Indian bats. “One Health approach with collaborative activities by the animal health and human health sectors in these surveillance activities shall be of use to public health,” the study published in the Indian Journal of Medical Research said.
“This would help in the development of diagnostic assays for novel viruses with outbreak potential and be useful in disease interventions. Proactive surveillance remains crucial for identifying the emerging novel viruses with epidemic potential and measures for risk mitigation,” said the study authored by Pragya D Yadav as the first author.

A study by the Indian Council of Medical Research (ICMR) has found the presence of a bat coronavirus in bat species from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu.
There have been studies and theories that the coronavirus pandemic which spread from Wuhan in China had originated from bats.
The ICMR study for the first time has found the presence of a different kind of coronavirus, bat coronavirus (BtCoV) in two bat species from these four states.

According to the study published in the Indian Journal of Medical Research, there is no evidence to suggest that the bat coronaviruses can cause disease in humans.

Bats from the Rousettus and Pteropus species from the four states were found positive. These bat coronaviruses are not related to the SARS-CoV2 which is causing the Covid 19 pandemic.
The 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’ said.

In conclusion, the study showed detection of pathogenic CoVs in two species of Indian bats. Continuous active surveillance is required to identify the emerging novel viruses with epidemic potential.
“There is a need of proactive surveillance of zoonotic infections in bats. Detection and identifications of such aetiological agents will provide leads for the development of diagnostic along with preparedness and readiness to deal with such emergent viruses thereby quickly containing them,” the study said.

The recognition and distinguishing proof of such infections from bats likewise prescribes cross-sectional counter acting agent overviews (human and residential creatures) in areas where the infections have been identified. Essentially, if epidemiological circumstance requests, proof based reconnaissance ought to likewise be directed. There is a need of creating solid components for working mutually with different partners, for example, natural life, poultry, creature cultivation and human wellbeing divisions.

In the current situation of changing demography and natural controls, it is trying to have keeps an eye on the experiences of bats with different creatures and people. Consequently, dynamic and consistent reconnaissance stays vital for flare-up alarms for bat-related viral operators with scourge potential, which would be useful in opportune intercessions, the investigation said.

In spite of the fact that CoVs in the subfamily Coronavirinae don’t for the most part produce clinical manifestations in their regular hosts (bats), unplanned transmission of these infections to people and different creatures may bring about respiratory, enteric, hepatic or neurologic maladies of variable seriousness. It is as yet not comprehended with regards to why just certain CoVs can contaminate individuals, the examination said.
