Rupee falls 43 paise to 74.11 against the US dollar in early trade

Chennai, Jul 1: In a case of cluster infection, 58 of the 65 mourners who attended the funeral a Central government official, Selvam, 56, who had worked in the Ministry of Foreign Trade and who died in Coimbatore and was brought for burial at Pannavaadi near Kolathur near Mettur in Salem district, tested positive for Covid-19, after three of them initially tested positive as they neither wore face masks not observed social distancing during the funeral, sources said.

Even as Dr Vijayabaskar said AIADMK MLA from Sriperumbudur, K Palani who tested positive for Covid-19 has recovered and will be discharged from hospital in couple of days, the MIOT International Hospital in Chennai said that the State Higher Education Minister, K P Anbazhagan, who initially showed no symptoms of coronavirus, subsequently tested positive in his second sample. He was now under treatment, his condition very stable and all his vital parameters are normal, MIOT said in a statement.

In what continues to be an unrestrained run, Tamil Nadu added its biggest day-wise spike so far of 3,943 positive Covid-19 cases, while another 60 deaths due to the novel coronavirus confirmed on Tuesday took the total death toll in the state to 1,201.

Of the new positive cases, Chennai alone accounted for its highest per-day jump of 2,393 positives with the number of persons tested today across Tamil Nadu put at 30,053. The total number os Covid-19 positive cases in the State as a whole till date is racing towards the one lakh mark at 90,167.

However, these outcomes are all on anticipated lines with the ICMR's push for more aggressive testing, even if they want lockdown controls to be now more focused at the district level, and want the Chennai model to be taken to the districts.

In this backdrop, the Health minister, Dr C Vijayabaskar chaired a detailed Covid review meeting this evening through video conference with all the hospital deans and other top officials on different facets of the disease prevention and control measures and the state's overall preparedness.

Chief Minister, Mr. Edappadi K Palaniswami in a statement in Chennai assured that with the 'full lockdown' continuing in greater Chennai, parts of three neighbouring districts of Chengalpattu, Thiruvallur and Kancheepuram and parts of Madurai district till July 5, the free community kitchens for the elderly, disabled and destitute will continue to function in those places till July 5 and hygienically cooked food packets served to them.

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, Jun 2: India on Tuesday reported 8,171 more COVID-19 cases and 204 deaths in the last 24 hours as the country's virus count inches closer to two lakh, according to the Union Ministry of Health and Family Welfare.

The total number of cases in the country now stands at 1,98,706 including 97,581 active cases, 95,527 cured/discharged/migrated and 5,598 deaths.

Cases in Maharashtra have crossed 70,000 including over 30,000 recovered while Tamil Nadu's COVID-19 tally jumped to 23,495.
