Earthquake of magnitude 3.5 hits Delhi-NCR

Thiruvananthapuram, Apr 16: Seven fresh cases of COVID-19 were reported from Kerala on Thursday, taking the total number of active cases to 147 in the state,even as over 88,000 people are under observation.

On Wednesday, only one positive case had been reported, thelowest in weeks.

While Kannur reported four cases, two were from Kozhikode and one from Kasaragod, Chief Minister Pinarayi Vijayan told reportershere.

Five of those affected had come from abroad, while two have got it through contact with infected people.

Samples of 27 people, including 24 from the worst affected Kasaragod, have turned negative on Thursday.

He said 394 coronavirus cases have so farbeen detected from the state.

Over 80,000 people are under observation, including 532 in various hospitals.

Vijayan said 17,400 samples have been sent for testing of which 16,459 have returned negative.

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, May 12: With 3,604 more COVID-19 cases reported in the last 24 hours, India's tally of coronavirus cases reached 70,756, said the Union Ministry of Health and Family Welfare on Tuesday. 87 deaths were reported during the period.

As per the tally, 46,008 patients are active coronavirus cases while 22,454 patients have been cured/discharged and one patient has migrated.

With 87 deaths due to COVID-19 reported in the last 24 hours, the number of deaths has risen to 2,293.

As per the ministry, Maharashtra has the most number of coronavirus cases with 23,401 cases with 4,786 patients being cured/discharged while 868 deaths have been reported in the state.

Gujarat is second on the list with 8,541 cases that include 2,780 patients recovering from the disease and 513 fatalities.

Tamil Nadu's tally reached 8,002 cases, including 2,051 recoveries and 53 deaths.

While Delhi's tally stands at 7,233 cases with 2,129 patients recovered and 73 deaths.

Meanwhile; Mizoram (one case reported--now recovered), Goa (seven cases reported and all seven recovered), Manipur (Two cases reported and both patients recovered) and Arunachal Pradesh (one case reported--now recovered) have reported no new cases in the last 24 hours.
