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.

Mar 21: India’s economy, already in the grip of a slowdown, is in for more pain after Prime Minister Narendra Modi appealed to citizens to stay at and work from home to curb the coronavirus outbreak.

The services sector, which accounts for about 55% of India’s gross domestic product, is poised to be the worst hit after Modi, in a late evening address on Thursday, urged citizens to go on a self-imposed curfew for a day and private companies to allow employees to work from home for longer. In the country’s vast informal sector, social-distancing measures could mean a dent to productivity and consumption because of job or pay losses.

“The impact of a partial lock-down or social distancing will be significant,” said Rahul Bajoria, a senior economist at Barclays Plc in Mumbai. “If there’s a widespread community outbreak, GDP could fall as low as 3.5% in the year starting April 1.”

Shrinking output may limit growth in an economy that’s already set to expand at an 11-year low of 5% in the current year to March 31. Before the virus outbreak, India had forecast growth to recover to 6%-6.5% in the next fiscal year. S&P Global Ratings and Fitch Ratings have already slashed their growth forecast by 50 basis points.

“The current social-distancing measures will severely impact airlines, hotels, malls, multiplexes, restaurants and retailers,” according to analysts at Crisil Ltd., the local unit of S&P Global. “Lower footfalls and occupancies, decline in business volume and sub-optimal operating efficiencies will impact cash flows of companies in these sectors,” wrote the analysts led by Chief Economist Dharmakirti Joshi.

The government will try to announce a relief package for virus-affected sectors as early as possible, Finance Minister Nirmala Sitharaman said Friday.

In a televised address, Modi advised all citizens to stay at home for a day on March 22, as he sought to stem the spread of the coronavirus -- cases of which are relatively low in India at about 200, compared with more than 200,000 infected people globally. His government also barred incoming flights for a week from that day, joining a growing list of countries effectively sealing their borders.

What Bloomberg’s Economists Say

We had only earlier this week lowered our GDP outlook to consider the direct impact of the local outbreak as confirmed virus cases exceeded 100 as of March 15 and the federal and state governments announced social distancing measures that have already started to crimp economic activity. We are now revising down our GDP estimate for 4Q fiscal 2020 to 3.3%, from our 3.5%.

“Consumption being the biggest component of GDP, a lock-down is bound to have a big impact on the economy,” said Devendra Kumar Pant, chief economist at India Ratings and Research, the local unit of Fitch. “Modeling uncertainty in any system will be very difficult, but one can say the slowdown could deepen or prolong further.”

Work From Home

While companies, including billionaire Mukesh Ambani-controlled Reliance Industries Ltd., are asking employees to work from home, the option isn’t feasible in India’s vast informal sector.

“The option to work remotely simply won’t exist for most,” said Shilan Shah, an economist with Capital Economics Pte. in Singapore.

As many households don’t have savings buffers, the government would probably have to back this up with large-scale cash handouts that reach the poorest, he said.

Work from home is posing implementation challenges for the manufacturing sector where workers are required to be physically present at the production sites. The services sector, such as banking and information technology, also needs employees to be present in offices as confidential data is used, according to industry group Federation of Indian Chambers of Commerce and Industry.

Prime Minister Narendra Modi, who had maintained silence on Chinese aggression and massacre of Indian in eastern Ladakh, now issued a statement saying ‘India wants peace’. He added that India is capable of giving a befitting reply if provoked. 

The prime minister started his meeting with chief ministers on the Covid-19 with a two-minute silence as a tribute to the 20 soldiers who were killed in action in Galwan Valley this week. As he spoke, it became clear that the message was aimed not just at reassuring the nation but also delivering a sharp message to Beijing.

“I would like to assure the nation that the sacrifice of our jawans will not be in vain. For us, the unity and sovereignty of the country is the most important,” PM Modi said. Home minister Amit Shah and defence minister Rajnath Singh were also present in the meeting.

Over twenty Indian soldiers were killed in the violent face-off which took place in Eastern Ladakh on Monday. The troops fought each other with fists and rocks. After the clash, the two sides “disengaged” from the area where the fighting happened, the Indian army statement said. A news agency quoting sources said four Indian soldiers are in critical condition after the face-off.

Defence minister Rajnath Singh mourned the death of 20 Indian soldiers. “The loss of soldiers in Galwan is deeply disturbing and painful. Our soldiers displayed exemplary courage and valour in the line of duty and sacrificed their lives in the highest traditions of the Indian Army,” he said in a statement.

“The Nation will never forget their bravery and sacrifice. My heart goes out to the families of the fallen soldiers. The nation stand shoulder to shoulder with them in this difficult hour. We are proud of the bravery and courage of India’s bravehearts,” the minister further said in the statement posted on Twitter.

These are the first Indian casualties in a border skirmish with PLA since October 1975 when Chinese troops ambushed an Indian patrol in Arunachal Pradesh’s Tulung La sector and shot four soldiers dead.
