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 16: With India's economic growth sputtering, the Reserve Bank of India was expected to maintain a rate-cutting cycle, but an uptick in near-term inflation could give the central bank's Monetary Policy Committee reason to pause for now.

Having cut its key lending rate by an aggressive 115 basis points (bps) in 2020, on top of 135 bps cuts in 2019, the RBI so far has had little success in spurring credit growth amid varying degrees of lockdowns across India.

Some economists and market insiders argue it may be prudent for the MPC, the policy committee, to hold its fire when it meets early next month.

"It's probably too early to administer a demand stimulus. The RBI still has room to cut rates, but we probably want to be more cautious of the timing," said Venkat Pasupuleti, portfolio manager at Dalton Investments.

"Maybe they should wait a quarter to see how things pan out once the lockdown situation is eased further."

Market participants have factored in at least a 25 bps rate cut by the MPC on August 6 while analysts are predicting a total 50-75 bps cuts over the rest of the fiscal year that runs to March 31.

The spike in the retail inflation rate above the RBI's mandated 2%-4% target range is another reason for the central bank to take a breather, analysts say.

Annual retail inflation rose to 6.09% in June, compared to 5.84% in March and sharply above a 5.30% median forecast in a Reuters poll of economists.

Rahul Bajoria, an economist at Barclays, said the spike in both consumer and wholesale prices "could lead to a tempering in enthusiasm for material front-loaded policy support from here on."

Almost all economists however agreed the RBI cannot move away from its accommodative stance or call an end to the rate cutting cycle just yet.

India's economy grew at 3.1% in the March quarter - an eight year low - and some economists have predicted a contraction of more than 20% in the June quarter and a contraction of up to 5% in the fiscal year.

"Even in the event of a pause, we think the RBI and MPC would want to hold out the promise of more cuts," said A. Prasanna, economist with ICICI Securities.

RBI Governor Shaktikanta Das said in a recent speech the need of the hour is to restore confidence, preserve financial stability, revive growth and recover stronger, suggesting inflation concerns are unlikely to deter the downward trajectory for rates too soon.

"The August policy decision would boil down to a judgment call over whether RBI can maintain easy monetary and financial conditions without the aid of a token rate cut," Prasanna said. 

New Delhi, Jul 12: With the highest single-day spike of 28,637 new cases and 551 deaths being reported in the last 24 hours, India's COVID-19 count reached 8,49,553 on Sunday.

According to the Union Health and Family Welfare Ministry, this includes 2,92,258 active cases, and 5,34,621 cured and discharged or migrated patients. The toll due to the disease has reached 22,674 in the country.

Maharashtra with 2,46,600 cases continues to be the worst affected state by COVID-19 in the country. The state has 99,499 active cases while 1,36,985 patients have been cured and discharged so far. The death toll due to the disease now stands at 10,116.

Tamil Nadu with 1,34,226 cases, including 46,413 active ones, is the next worst affected in the country. While the number of cured and discharged patients is at 85,915 in the state, the toll due to the disease is at 1,898.

The national capital has recorded 1,10,921 confirmed cases so far. However, the number of active cases in Delhi is at 19,895 and 87,692 patients have been cured and discharged so far. With 3,334 deaths being reported due to COVID-19 in the city.
