Probe everybody including PM Modi in Rafale scam: Rahul Gandhi

New Delhi, Jun 20: The government-imposed upper and lower limits on airfares may be extended beyond August 24 depending upon how the situation turns out, Aviation Secretary P S Kharola said on Saturday.

The government resumed domestic passenger flights from May 25 after nearly two months of suspension to combat the coronavirus outbreak, but placed lower and upper limits on airfares depending upon the flight duration.

It had said on May 21 that these limits would be in place for a period of three months.

"Depending on how the situation turns out, the fare band may have to adjusted beyond that (August 24) also. But right now, it is only for three months," Kharola said at a press conference here.

International passenger flights continue to remain suspended in the country.

However, the government started Vande Bharat Mission on May 6 to help stranded people reach their destinations through special flights.

Aviation Minister Hardeep Singh Puri said at the conference that during phase 3 and phase 4 of the mission, private domestic airlines have been approved to operate 750 international flights to repatriate people stranded amid the coronavirus pandemic.

New Delhi, Jan 28: Kolkata Metro Rail Corp expects to complete its East-West project, which runs partly under the city’s iconic Hooghly river, by March 2022 after a delay of several years doubled costs.

The authority is awaiting a final installment of Rs 20 crore ($2.8 million) over the next two years from the Indian Railway Board, said Manas Sarkar, managing director at KMRC. A soft loan of Rs 4,160 crore from Japan International Cooperation Agency helps fund 48.5% of the project.

India’s oldest metro, which started in 1984 with a North-South service, was due to expand by 2014 but faced problems including squatters on the planned route. These issues have contributed to the total project cost rising to about Rs 8,600 crore for some 17 kilometers from Rs 4,900 crore for 14 km.

“About 40% of total transport demand will be tackled by these two metro services,” Sarkar said in an interview at his office in Kolkata. “It will be a relief for environmental pollution and the city should be much more decongested.”

The new line is expected to carry about 900,000 people daily, -- roughly 20% of the city’s population -- and will take less than a minute to cross a 520-meter underwater tunnel. Depending on the time of day, it takes some 20 minutes to use the ferry and anywhere upward of an hour to cross the Howrah bridge.

KMRC will repay the JICA loan over 30 years after an initial six-year moratorium. The interest rate is between 1.2% to 1.6%. The East-West metro project is 74% owned by the railway ministry and 26% by the ministry of housing and urban affairs.

“We don’t anticipate any further cost escalation now,” Sarkar said.

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.
