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, Apr 22: Philanthropist and Microsoft co-founder Bill Gates has lauded Prime Minister Narendra Modi's leadership in dealing with COVID-19 pandemic by adopting several measures including lockdown and increasing health expenditure to strengthen the health system response.

"We commend your leadership and the proactive measures you and your government have taken to flatten the curve of the COVID-19 infection rate in India, such as adopting a national lockdown, expanding focused testing to identify hot spots for isolation, quarantining, and care, and significantly increasing health expenditures to strengthen the health system response and promote R&D and digital innovation," Gates wrote.

He added: "I'm glad your government is fully utilising its exceptional digital capabilities in its COVID-19 response and has launched the Aarogya Setu digital app for coronavirus tracking, contact tracing, and to connect people to health services."

Prime Minister Modi had on March 24 announced a 21-day nationwide lockdown as a precautionary measure to contain the spread of COVID-19. The lockdown was later extended to May 3.

Gates further stated, "Grateful to see that you are seeking to balance public health imperatives with the need to ensure adequate social protection for all Indians."

With 1,486 new cases and 49 deaths in the last 24 hours, India's total number of coronavirus positive cases have risen to 20,471 while the death toll stands at 652, Union Ministry of Health and Family Welfare said on Wednesday.

Out of the total number of cases, 15,859 are active cases, 3,959 cured or discharged or migrated and 652 deaths.

Bill Gates met Prime Minister Modi in New Delhi on November 18 last year.

During his visit, Gates had addressed a function organised by NITI Aayog for the release of its report on 'Health Systems for a New India: Building Blocks - Potential Pathways to Reforms' wherein he lauded the country for its healthcare system and talked about how digital tools can help improve it further.

At that time, the philanthropist had commended the Central government for stepping up and eradicating polio.

New Delhi, Mar 31: The total number of coronavirus cases in India has risen to 1,397 after 146 new patients were reported in the last 24-hours, the Ministry of Health and Family Welfare said on Tuesday.

Of this little less than 1,400 cases, there are 1,238 active while 124 cured. The total figure also includes 35 fatalities.
