SC to hear on Friday plea of two women who entered Sabarimala temple

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, July 13: The number of active Covid-19 cases in India crossed the 3 lakh mark on Sunday even as fresh infections during the day surged to another new peak, crossing 29,000 for the first time. After staying over 500 for the past two days, the daily death toll came down slightly to 492.

While the focus has been on recoveries, the number of active Covid-19 cases in the country has been steadily rising. It hit the 1 lakh mark on June 4 and went past 2 lakh 23 days later. It has taken just 15 days more to reach 3 lakh.

India reported 29,271 new cases on Sunday, the fifth straight day of record rise in daily infections. With this, the country’s coronavirus caseload has risen to 8,79,060, two days after hitting the 8 lakh mark, as per data collated from state governments. Active cases stood at 3,02,466 while more than 5.53 lakh people were declared cured of the infection.

Covid-19 deaths in the country rose to 23,175 after 492 fatalities were added on Sunday, translating to a case fatality rate of 2.6%. The CFR has been steadily dropping with the surge in cases.
 

Panaji, Mar 26: Three persons, all with travel history abroad, tested positive for coronavirus in Goa on Wednesday, health department officials said, as the tourist haven joined the states which have reported COVID-19 cases.

This is the first time the tourist state has reported coronavirus positive cases.

The Directorate of Health Services, in a late night press statement here, said three suspected cases of COVID-19 from Goa, whose test results were awaited, have turned out positive.

All three are male patients of ages 25, 29 and 55 years. They have travel history of returning to Goa from Spain, Australia and the USA, respectively, the officials said.

The condition of the trio, admitted in Goa Medical College and Hospital near here, is stable, the officials added.

Chief Minister Pramod Sawant said the state is providing the best healthcare facility to the diagnosed patients.

I have been informed by the state Directorate of Health services that three individuals have been tested positive for #COVID19 in Goa.

"We are providing the best healthcare facility to the diagnosed patients, he said.

Their condition is stable at present. e have also traced their contacts and are quarantining them, Sawant added.

Health Minister Vishwajit Rane said the government is taking all precautions and following guidelines related to the viral infection.

In view of the three positive coronavirus cases in Goa, we are following all guidelines laid down by the central government and taking all precautions with the support of chief minister Pramod Sawant, he said.

Our testing facility will be up and running in the next two days. Our team of doctors is doing its est to make sure we contain the spread of virus in the state, Rane added.
