ND Tiwari is biological father of Rohit Shekhar: DNA test

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.

May 30: A total of 513 domestic flights carrying 39,969 passengers were operated in India on Friday, Civil Aviation Minister Hardeep Singh Puri said on Saturday.

Domestic services resumed in India after a gap of two months due to the coronavirus lockdown. Indian carriers have operated a total of 1,827 flights till Thursday -- 428 on Monday, 445 on Tuesday, 460 on Wednesday and 494 on Thursday.

Puri said on Twitter on Saturday: "Day 5. 29th May till 2359 hrs. Departures 513. 39,969 passengers handled. Arrivals 512. 39,972 passengers handled." A departure is counted as a flight during the day.

During the pre-lockdown period, Indian airports handled around 3,000 daily domestic flights, aviation industry sources said.

In February, when the lockdown was not imposed, around 4.12 lakh passengers travelled daily through domestic flights in India, according to Directorate General of Civil Aviation (DGCA) data.

Airports in West Bengal, Andhra Pradesh, Maharashtra, Telangana and Tamil Nadu have been allowed to handle a restricted number of daily flights as these states do not want a huge influx of flyers amid the rising number of COVID-19 cases.

While domestic services resumed in Andhra Pradesh on Tuesday, they restarted in West Bengal on Thursday.

Though domestic flight operations across the country began on May 25, they could not be restarted in Kolkata and Bagdogra as the West Bengal machinery was involved in relief and restoration work after cyclone Amphan's devastation.

A total of 16 asymptomatic passengers on seven different flights, including 13 who travelled by IndiGo, have tested positive for COVID-19 since the resumption of domestic air services.

Jan 24: India’s economy appears to be shaking off a slump, as activity in the services and manufacturing sectors expanded for a second straight month in December.

The needle on a gauge measuring so-called animal spirits signaled the economy may be taking a turn for the better, as five of the eight high-frequency indicators tracked by Bloomberg News came in stronger last month. The dial was last at the current position in August.

“Animal spirits” is a term coined by British economist John Maynard Keynes to refer to investors’ confidence in taking action, and the gauge uses the three-month weighted average to smooth out volatility in the single-month numbers.

The nascent recovery would need a helping hand, with expectations building that Finance Minister Nirmala Sitharaman will provide some stimulus when she presents the budget Feb. 1. Official forecasts show the economy is set to expand at 5% in the year ending March 2020 -- the weakest pace in more than a decade.

Here are the details of the dashboard:

Business Activity

The dominant services index rose to the highest level in five months in December as improving new work orders helped boost activity. The seasonally adjusted Markit India Services PMI index climbed to 53.3 from 52.7 in November, helping post a strong end to the calendar year.

India’s manufacturing PMI also rose -- to 52.7 from 51.2 a month ago -- boosted by the fastest increase in new orders since July. A reading above 50 means expansion while anything below that signals contraction.

The uptick in business confidence was accompanied by a rise in inflationary pressures, the survey showed. That trend may keep monetary policy makers from resuming interest-rate cuts anytime soon, leaving most of the heavy-lifting to boost growth with the government.

“The relative stability in macro indicators over the past two months suggests that the worst is behind, but the recovery is likely to be prolonged,” said Teresa John, an economist at Nirmal Bang Equities Pvt. in Mumbai. “Still, sluggish growth and rising inflation indicate that India may well remain in stagflation for most of 2020.”

Exports

Exports remained a laggard, falling 1.8% in December from a year ago. The drag was mainly because of a fall in export of engineering goods, which constitute a third of India’s non-oil exports.

Capital goods imports continued to contract and was lower by 16.5% year-on-year in December after a 22% drop in November. This was the seventh consecutive month of continuous decline, underscoring the weakness in the capex cycle, according to IDFC First Bank.

Consumer Activity

Weakness in demand for passenger vehicles persisted, with local sales falling 1.2% in December from a year ago, according to the Society of Indian Automobile Manufacturers. That capped the worst yearly passenger vehicle sales on record. A Nielsen study on demand for fast-moving consumer goods showed volume growth dropped to 3.5% in the last quarter of 2019 from 3.9% in the same period of 2018.

Funding conditions held out hope, showing considerable improvement in December, according to the Citi India Financial Conditions Index. Credit growth remained tardy though, with demand for loans rising at a slower 7.1% pace from a year ago compared with a nearly 8% growth in November.

Industrial Activity

Industrial output rose for the first time in four months in November. The pick up was broad-based, led by mining, manufacturing and electricity. Mining and manufacturing, in particular, posted a second month of sequential growth. Production of consumer goods also rose after a few months of contraction.

The index of eight core infrastructure industries, which feeds into the index of industrial production, however, declined 1.5% in November from a year ago -- the fourth straight month of contraction. That was on account of shrinking production of electricity, steel, coal, natural gas and crude oil. Both the core sector and industrial output numbers are reported with a one-month lag.
