Scrapping of Amethi food park: Rahul raises issue in LS

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, Apr 27: A private hospital here claimed that a coronavirus patient, who was administered plasma therapy for the first time in the facility, was discharged on Sunday after being completely cured.

The 49-year-old man had tested positive for COVID-19 on April 4 and was admitted to Max Hospital, Saket, it said in a statement.

As his condition deteriorated, he was put on ventilator support on April 8, the hospital added.

When the patient showed no signs of improvement, his family requested for administration of plasma therapy on compassionate grounds, it said, adding that the family arranged a donor for extracting plasma.

The patient was administered fresh plasma as a treatment modality as a side-line to standard treatment protocols on the night of April 14, the statement said.

Subsequently, the patient showed improvement and by the fourth day, was weaned off ventilator support and continued on supplementary oxygen. He was shifted to a room with round-the-clock monitoring on Monday after testing negative twice within 24 hours, it said.

He has now fully recovered and was discharged, the hospital said, adding that he will stay at home for another two weeks.

Group medical director of Max Healthcare and senior director of the Institute of Internal Medicine Dr Sandeep Budhiraja said, "We can say that plasma therapy could have worked as a catalyst in speeding up his recovery. We cannot attribute 100 per cent recovery to plasma therapy only, as there are multiple factors which carved his path to recovery."

Kolkata, July 13: Debendra Nath Roy, a member of the West Bengal legislative assembly (MLA) from the Bharatiya Janata Party (BJP), was found dead near his house in north Bengal’s Uttar Dinajpur district on Monday morning.

BJP leaders and his family members have alleged that he was murdered. 

BJP president JP Nadda has expressed “shock” at Roy’s “deplorable and suspected heinous killing” and condemned the incident.

He questioned the rise of “gunda raj” in West Bengal under Chief Minister Mamata Banerjee’s watch amid the worsening law and order in the state, which is slated to hold assembly polls next year, where the BJP is seen to be the primary challenger to the CM’s citadel.

“The suspected heinous killing of Debendra Nath Ray, BJP MLA from Hemtabad in West Bengal, is extremely shocking and deplorable. This speaks volumes of the gunda raj and failure of law and order in the Mamata Banerjee-led government. People will not forgive such a government in the future. We strongly condemn the incident,” he tweeted.

The BJP has demanded a Central Bureau of Investigation (CBI) probe into the lawmaker’s unnatural death.

His body was found in the balcony of a shop near his house at Bondol in Hemtabad, Uttar Dinajpur district, on Monday morning.

“The body has been sent for autopsy. We are investigating the case. No one has been detained for questioning or arrested so far,” said a police official from Uttar Dinajpur district, requesting anonymity.

“Roy was murdered. The way his body was found suggests that it was a premeditated murder and the accused tried to pass it off as a suicide. The ruling TMC (Trinamool Congress) is involved in his murder,” alleged Rahul Sinha, national secretary, BJP.

The TMC, however, refuted the BJP’s allegations.

“I heard that he (Roy) died by suicide. Police are investigating the case. Let the truth come out. If he has been murdered, then the culprits should be identified and punished as per law,” said Kanhaiyalal Agarwal, a TMC leader from Uttar Dinajpur district.

BJP leaders said some people had called Roy around 1 am on Monday and he went out of his home. His body was found on Monday morning.

Roy had won the Bengal assembly elections from Hemtabad on a Communist Party of India (Marxist) ticket in 2016, but joined the BJP last year.
