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, Jul 19: India's Covid-19 case fatality rate is "progressively falling" and is currently at 2.49 per cent, which is one of the lowest in the world, the Union Health Ministry said on Sunday, crediting efficient clinical management of hospitalised cases for it.

There are 29 states and union territories with a case fatality rate (CFR) lower than India's average, with five of them having a CFR of zero and 14 having fatality rate of less than 1 per cent.

The focused efforts of the Centre and state and UT governments on efficient clinical management of hospitalised cases have ensured that India's case fatality rate has fallen below 2.5 per cent, the ministry said.

With effective containment strategy, aggressive testing and standardized clinical management protocols based on holistic standard of care approach, the CFR has significantly dipped, it said.

"The CFR is progressively falling and currently, it is 2.49 per cent. India has one of the lowest fatality rates in the world," the ministry said.

From 2.82 per cent over a month earlier, India's Covid-19 case fatality rate declined to 2.72 per cent on July 10 and has further reduced to 2.49 per cent presently.

Under the guidance of the Centre, the state and UT governments have ramped up testing and hospital infrastructure by combining public and private sector efforts, the ministry said.

Many states have conducted the population surveys to map and identify the vulnerable population like the elderly, pregnant women and those with co-morbidities.

This, with the help of technological solutions like mobile apps, has ensured keeping the high-risk population under continuous observation, thus aiding early identification, timely clinical treatment and reducing fatalities, the ministry said.

"At the ground level, frontline health workers like ASHAs (Accredited Social Health Activists) and ANMs (Auxiliary Nursing Midwives) have done a commendable job of managing the migrant population and to enhance awareness at the community level.

"As a result, there are 29 States and UTs with CFR lower than India's average. This shows commendable work done by public health apparatus of the country," the ministry said.

Manipur, Nagaland, Sikkim, Mizoram, Andaman and Nicobar Islands have zero case fatality rate.

States and UTs having a CFR below the national average include Tripura (0.19 pc),  Assam (0.23 pc), Kerala (0.34 pc), Odisha (0.51 pc), Goa (0.60 pc), Himachal Pradesh (0.75 pc), Bihar (0.83 pc), Telangana (0.93 pc), Andhra Pradesh (1.31 pc), Tamil Nadu (1.45 pc), Chandigarh (1.71 pc), Rajasthan (1.94 pc), Karnataka (2.08 pc) and Uttar Pradesh (2.36 pc).

India saw a record single-day jump of 38,902 Covid-19 cases pushing its tally to 10,77,618 on Sunday, while the total number of recoveries increased to 6,77,422.

A total of 23, 672 patients have recuperated in the past 24 hours, the highest so far in a day, according to the health ministry data updated at 8 AM.

According to the Indian Council of Medical Research (ICMR), a cumulative total of 1,37,91,869 samples have been tested up to July 18 with 3,58,127 samples being tested on Saturday. 

Hyderabad, Jun 20: IAF Chief Air Chief Marshal RKS Bhadauria on Saturday said that the force is well prepared and suitably deployed to respond to any contingency and it will never let the sacrifice of the bravehearts of Galwan go in vain.

"It should be very clear that we are well prepared and suitably deployed to respond to any contingency. I assure the nation that we are determined to deliver and will never let the sacrifice of the braves of Galwan go in vain," IAF Chief Air Chief Marshal Bhadauria said here.

Bhadauria was speaking at the Combined Graduation Parade (CGP) at Air Force Academy in Hyderabad.

His remarks come days after 20 Indian soldiers lost their lives in the violent face-off on June 15-16 during an attempt by the Chinese troops to unilaterally change the status quo during the de-escalation in eastern Ladakh.

Speaking about the current border situation with China, he said: "We are aware of the situation, be it on LAC or beyond, be it their air deployments, their posture and kind of deployments. We've full analysis and we have taken necessary action that we need to take to handle any contingency that may come up."

"We are monitoring all the moments and we are aware of the full situation," he added.

He further said that in spite of the "unacceptable Chinese action" at Galwan Valley in eastern Ladakh, which claimed lives of 20 Indian Army personnel, efforts are underway to ensure that the current situation at the Line of Actual Control (LAC) is resolved peacefully.

He asserted that the IAF is determined to deliver and the development at the LAC in Ladakh is a small snapshot of what the force is required to handle at short notice.

The IAF Chief further appealed to people to join him in paying tribute Colonel Santosh Babu and his brave men who made the sacrifice while defending the LAC in Galwan valley.

"The gallant actions in a highly-challenging situation have demonstrated our resolve to protect India's sovereignty at any cost," the Indian Air Force (IAF) chief said.
