BJP defends Pranab, warns Kejriwal against questioning credibility of Prez’s office

New Delhi, Jul 10: With the highest single-day spike of 26,506 COVID-19 cases and 475 deaths reported in the last 24 hours, the total number of COVID-19 cases in India reached 7,93,802 on Friday, according to the Union Ministry of Health and Family Welfare.

Out of the total number of cases, 2,76,685 are active, 4,95,513 have been cured/discharged/migrated and 21,604 have died so far due to the infection.

With as many as 2,30,599 COVID-19 cases, Maharashtra continues to remain the worst-affected state, followed by Tamil Nadu (1,26,581) and Delhi (1,07,051).

Meanwhile, 2,83,659 samples were tested for coronavirus on Thursday, taking the total number of samples tested up to July 9 to 1,10,24,491, according to the Indian Council of Medical Research (ICMR).

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 29: More than 38,000 doctors, including those retired from the Armed Forces Medical Services, have volunteered to help the government in its fight against COVID-19 pandemic, a senior official said on Friday.

On March 25, the government had made an appeal to doctors, including the retired ones, to come forward and join the efforts to fight the pandemic.

"38,162 volunteer doctors, including retired government, Armed Forces Medical Services, public sector undertaking or private doctors have signed up with the government to battle COVID-19 pandemic," the official said.

The official further said Niti Aayog has sent a list of names of these doctors to Ministry of Health and Family Welfare and National Disaster Management Authority (NDMA).

In a statement posted on Niti Aayog's website on March 25, the government had said those who wish to contribute to this noble mission may register themselves through a link provided on the Aayog's website.

"The Government of India requests for volunteer doctors who are fit and willing to be available for providing their services in the public health facilities and the training hospitals in the near future.

"We appeal to such doctors to come forward at this hour of need. You could also be a retired government, Armed Forces Medical Services, public sector undertaking or a private doctor," the statement had said.

It had noted that in case the outbreak leads to a high number of infected individuals, India's public health facilities will face tremendous load to take care of a large number of patients.

Many countries, including the US, Italy, the UK and Vietnam, had also urged retired health workers to come back to work amid the pandemic.

The number of COVID-19 cases in India has climbed to 1,65,799, making it the world's ninth worst-hit country by the coronavirus pandemic.

The Health Ministry on Friday said the death toll due to COVID-19 rose to 4,706 in the country.
