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.

Kochi, Apr 10: Kerala government is winning accolades for saving the life of eight foreigners including a very serious UK citizen who had been undergoing critical care for COVID-19 at a hospital here.

All the persons have been completely cured with the declaration of the test result of four persons. The persons, Roberto Tonozo (57) of Italy, Lanson (76) of UK, Elizabeth Lance (76), Brial Neil (57), Janet Layi (83), Steeven Hankok (61), Annie Wilson (61) and Jan Jackson (63) were completely cured and preparing to go for their countries, an official statement said on Thursday.

The last four persons who were cured expressed their desire to undergo treatment at a private hospital here.

Muzaffarpur, Mar 18: Prisoners in the central jail here are working overtime to produce facemasks to prevent the deadly COVID-19 striking. In addition to providing protection to fellow inmates and prison staff, the produce will be shared with nine district and sub jails falling under Muzaffarpur Central Prison as well, Deputy Superintendent of the jail Sunil Kumar Maurya said. From supplications at places of worship to hectic activities at the biggest hospital, this north Bihar district is witnessing invocation of all powers, human and otherwise, to prevent novel coronavirus hitting them.

Although nobody has so far tested positive for the dreaded virus in Bihar, where the state government has imposed a semi-lockdown as a preventive measure, Muzaffarpur which hit the headlines last year for losing close to 200 children to an outbreak of brain fever seems determined not to fall prey to yet another virulent affliction.

On making of facemasks by about 50 prisoners, the Deputy Superintendent of the jail said, "We have had a tradition of producing fabric at the Muzaffarpur Central Jail. An idea was floated why not use the skills acquired for producing masks which are in great demand but in short supply.

The local administration seems impressed with the endeavour of the social outcasts to rise to a global challenge.

"It is a welcome step. Despite all precautions, we never know who is going to catch the infection at which place. The efforts by prisoners to protect themselves and the staff manning their premises is laudable. "Full assistance will be provided to Central Jail authorities in supply of the masks to other prisons," Sub Divisional Magistrate (East) Kundan Kumar said.

A conservative town inhabited by a deeply religious citizenry, Muzaffarpur is also witnessing prayer congregations at temples and mosques in keeping with the tradition here of people of all faiths coming together when faced with a major challenge.

The Garib Nath temple, a renowned shrine devoted to Lord Shiva which attracts devotees from far and wide, is witness to the power of faith trumping the biggest fears as the footfall seems to have increased since the outbreak.

The temples mahant Vinay Pathak says, "faith can move mountains. People come here in search of strength to face a crisis which has caused worldwide scare. We advise the visitors to conduct regular 'havans' at their houses just like we have been performing here. "The smoke emitted by burning of purified offerings cleanses the air and, who knows, could be an antidote as well," Pathak added.

Chanting of 'Mahamrityunjay mantra', which the faith believe to be potent enough to dispel illness and untimely death, is taking place round the clock at the shrine in addition to 'havans', the mahant said.

Just a few yards away stands the Chhata Chowk mosque where large number of devotees appear in skull-caps to offer namaz.

"It is a pandemic threatening to engulf the entire world and dua (prayers) are needed as much as dawa (medicines). May God, who is one, listen to the common wish expressed by humanity in myriad ways," says Imtiaz Ahmed, a devout local resident.

Meanwhile, the health authorities are busy with their own efforts, not leaving prevention and cure to divine intervention.

District Medical Officer Shailesh Kumar Singh says a total of 42 people here who have come from abroad, have been tested but their results have been negative.

"Nonetheless, a five-bed special ward has been set up at the Sadar Hospital, manned by medical staff armed with a special kit comprising medicines and other logistics required for primary care of those with suspected symptoms," he said.

The SKMCH referral hospital, which bore the brunt of last years brain fever epidemic accounting for over 120 deaths is fully geared up to meet the latest challenge.

SKMCH superintendent Sunil Shahi says "we have a 30- ward insulation ward ready. Samples of patients with suspected symptoms are being routinely sent to RMRI, Patna. We appeal to all to remain alert, but avoid panic."
