Centre rolls out Rs 80,000 a month PhD grant to plug brain drain

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, Mar 23: The total number of COVID-19 cases in the country rose to 390 on Monday after 30 fresh cases were reported.

The figure includes 41 foreign nationals and the seven deaths reported so far.

Gujarat, Bihar and Maharahstra reported a death each on Sunday, while four fatalities were reported earlier from Karnataka, Delhi, Maharashtra and Punjab, the Union Health Ministry said.

The total number of active COVID-19 cases across the country now stands at 359, while 24 people have been cured/discharged/migrated.

New Delhi, June 8: Only 20.26 lakh migrant workers of the targeted 8 crore such labourers have received free food grains in May and June (2020), according to data released by the Ministry of Consumer Affairs, Food and Public Distribution.

In the middle of May, as part of the Rs 20 lakh crore Atma Nirbhar Bharat package, the Modi government had announced that migrant labourers who are not covered under the National Food Security Act (NFSA) or any state-run PDS scheme, will receive free food grains for two months.

"Non-card holders shall be given 5 kg wheat or rice per person and 1 kg chana per family per month for the next 2 months. About 8 crore migrants will benefit from this scheme that will cost the government Rs 3500 crore,” Finance Minister Nirmala Sitharaman had said at a press conference following PM Modi’s announcement.

But the Ministry of Consumer Affairs, Food and Public Distribution said on Sunday, "The states and UTs have lifted 4.42 LMT (lakh metric tonne) of food grains and distributed 10,131 MT of it to 20.26 lakh beneficiaries."

It added, "The Government of India also approved 39,000 MT pulses for 1.96 crore migrant families. Around 28,306 MT gram/dal have been dispatched to the states and UTs. A total 15,413 MT gram have been lifted by various states and UTs". The state governments, the ministry added, had distributed only 631MT (metric tonnes) of gram so far.

Because of the constant movement of migrant workers, the Centre had said that the states will be responsible for identifying the migrants and subsequent food distribution.

The Centre claims it is spending approximately Rs 3,109 crore for food grains and Rs 280 crores for grams/chana under this package.
