Excess baggage fee in domestic flights may see 300% hike

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, Feb 3: The Allahabad High Court on Monday granted bail to former BJP leader Swami Chinmayanand in the alleged rape case of a law student. He was arrested in September last year after the 23-year-old woman accused him of sexual harassment and blackmail.

The woman was a student of the Chinmayanand-controlled SS Law College in Shahjahanpur in Uttar Pradesh.

Chinmayanand is facing charges under Sections 376C (sexual intercourse by a person or persons taking advantage of their official position), 354 D (stalking), 342 (wrongful confinement) and 506 (criminal intimidation) of the Indian Penal Code (IPC).

The case is being investigated by a Special Investigation Team (SIT) formed on the directions of the Supreme Court.

The case came to light after the woman posted a video on August 23 last year on social media alleging that “a senior leader of the saint community” was harassing and threatening to kill her. The law student went missing a day later, after which her father lodged a complaint, accusing Chinmayanand of harassing his daughter.

Chinmayanand was expelled from the BJP after his arrest.

The SIT had, on November 6, submitted chargesheet in the case.

In a parallel case, the woman was charged with trying to extort money from Chinmayanad. The Allahabad High Court granted her bail in that case in December last year.

Feb 28: National oil marketer Indian Oil Corporation (IOC) on Friday said it is ready to supply low emission BS-VI fuels from April 1 and that there will be a marginal increase in retail prices.

The largest oil supplier has spent over Rs 17,000 crore to upgrade its refineries to produce the low-sulfur diesel and petrol, the company's chairman Sanjiv Singh told reporters here.

Without disclosing the quantum of price increase, Singh said, “there will definitely be a marginal increase in retail prices of the fuels from April 1 when the whole country will be run on new fuels, which will have a sulphur content of only 10 parts per million (ppm) as against the present 50 ppm.

“But let me assure you, we will not be burdening the consumers with a steep hike,” Singh said.

He said, state-run oil marketing companies (OMCs) have invested Rs 35,000 crore to upgrade their refineries, of which Rs 17,000 crore have been spent by IOC alone.

Earlier this week, the sell-off bound BPCL said it had invested around Rs 7,000 crore for the same. ONGC-run HPCL has not so far disclosed its readiness for BS-VI supplies or its capex on the same.

HPCL had said from February 26-27 it was ready with BS-VI fuels and that it would sell only the new fuels from March 1.

IOC switched to BS-VI fuel production a fortnight ago and all its depots and containers are ready now, Singh said.

However, he said some remote locations, where the intake is very low, will take some more time to switch. But the company is planning to drain out the entire BS-IV stock and replenish the new fuels at such locations, he added.

Further, it has been reported that the companies will have to increase prices by 70-120 paise a litre, but Singh said, to arrive such a weighted average is not possible given the complexities of each refinery.

He, however, asserted that the price hike will not be a burden on consumers.

We are not looking at this investment from a pure return on investment basis, but this is a national mandate and we have done it.

Having said that, all those countries that moved to low emission fuels are charging higher prices; and from April 1, our prices will also be benchmarked against Euro VI prices as against the present practice of the cost-plus model, Singh concluded.
