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 15: The number of novel coronavirus cases in the country rose to 107 on Sunday, with 12 fresh cases in Maharashtra, the Union Health Ministry said.

The number of cases include two persons who died in Delhi and Karnataka.

While a 76-year-old man from Kalaburagi who had recently returned from Saudi Arabia died on Thursday, a 68-year-old woman in Delhi who had tested positive for coronavirus passed away at the Ram Manohar Lohia (RML) Hospital on Friday night.

Delhi has reported seven positive cases and Uttar Pradesh 11 so far. Karnataka has six coronavirus patients while Maharashtra 31, Ladakh three and Jammu and Kashmir 2. Telangana reported three cases.

Besides, Rajasthan also reported two cases. Tamil Nadu, Andhra Pradesh and Punjab have reported one case each.

Kerala has recorded 22 cases, including three patients who were discharged last month after they recovered from the contagious infection with flu-like symptoms.

The total number of confirmed cases includes 17 foreigners -- 16 Italian tourists and a Canadian, the ministry officials said

Amid rising coronavirus cases in India, the government has asked people not to panic, saying no community transmission of the virus has been observed and there has only been a few cases of local transmission so far and that it is "not a health emergency" in India at present.

With the World Health Organisation (WHO) declaring COVID-19 a pandemic, a Health Ministry official said over 4,000 people who had come in contact with the 93 positive cases have been identified through contact tracing and were being tracked while 42,000 people across the country are under community surveillance.

He said all essential facilities like community surveillance, quarantine, isolation wards, adequate personal protective equipment (PPEs), trained manpower, rapid response teams are being strengthened further in all states and union territories.

The government on Wednesday suspended all visas, barring a few categories like diplomatic and employment, in an attempt to prevent the spread of coronavirus.

It has asked Indian nationals to avoid all non-essential travel abroad.

All incoming international passengers returning to India should self-monitor their health and follow the required do's and dont's as detailed by the government.

Mar 12: Three women were arrested for allegedly administrating fake coronavirus vaccines to villagers in Maharashtra's Jalna district, police said on Thursday.

The police on Wednesday arrested Beed residents Radha Ramnath Saamse, Seema Krishna Andhale and Sangeeta Rajendra Avhad, who allegedly posed as doctors and healthcare workers, an official said.

The trio met villagers of Pipalgoan in Ambad tehsil, informed them about a vaccine that could protect them from coronavirus and administered it to gullible locals, he said.

Some villagers informed Dr Mahadev Munde, a medical officer at a rural health centre, about this, after which a complaint was lodged, the official said.

Fake vaccines and bottles, which were seized from the accused, have been sent to the state health department, he said, adding that a case of cheating has been registered against the trio.
