Obama accepts PM Modi's Republic Day invitation

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 28: Nafisa Ali took to Instagram to share the inspiring story of her niece, Diya Naidu, who donated her plasma to help patients suffering from Covid-19 after recovering from the disease. The veteran actress shared a photo of her niece from the hospital bed and asked fans to read Diya's post to get a detailed account of her experience.

Nafisa wrote, "Diya Naidu my niece - a COVID19 hero - is back home after donating her plasma - looks like liquid gold - it’s value is priceless as it will save lives. So please read her COVID19 story and share the information that is first hand. It is the need of the hour. Help save lives. #diyanise. #diyanaidu #covid_19 #india (sic)."

Diya Naidu, who is a dancer and choreographer based in Bengaluru, revealed in her Instagram post that she has donated her plasma for other Covid-19 patients. She said that the method has been super effective wherever it's been tried.

Earlier, Nafisa Ali gave a shout-out to her niece on Instagram and penned a heartfelt note for her. She wrote, "I am so grateful to you brave child - a COVID19 warrior (living in Bangalore) has agreed to donate her plasma to help cure other COVID19 serious patients (sic)."

Explaining the process of plasma therapy to treat Covid-19 patients, she wrote, "The process of donating plasma to treat COVID-19 is not very complex and can be done in just two hours. One of the most discussed methods of treatment of the disease caused by the novel coronavirus is plasma therapy, which involves the transfusion of plasma from a convalescent coronavirus patient to a critical patient. The blood of a recovering patient is rich in antibodies produced by the body to fight the virus, which are expected to help the critical patient recover (sic)."

Plasma therapy has been suggested to treat people suffering from Covid-19. People, who have recovered from the disease, are donating plasma as it contains antibodies to fight the disease. Earlier, Kanika Kapoor, who was the first Bollywood celebrity to be diagnosed with the disease, also offered to donate her plasma. She has recovered from Covid-19 and is currently living with her family in Lucknow.

Seventy-seven per cent children below five years of age in Jammu and Kashmir were not able to access basic healthcare services like immunisation during the lockdown imposed to curb the spread of COVID-19, CRY said on Monday citing a study.

The 'Rapid Online Perception Study about the Effects of COVID-19 on Children' was conducted during the first and second phases of the lockdown based on responses of parents and primary caregivers from all across the country, including Jammu and Kashmir, the NGO said in a statement.

It said a total of 387 respondents from Jammu and Kashmir participated in the study.

"Seventy-seven per cent children of age 0-5 years were not able to access basic healthcare services such as immunisation during lockdown - necessarily imposed to curb the spread of COVID-19 pandemic in Jammu and Kashmir," Child Rights and You (CRY) said.

It said as immunisation programmes witnessed a major setback during the lockdown across the country, the results of the survey across 23 states and Union Territories found nearly 50 per cent of parents with children below five years of age unable to access immunisation services.

"Worryingly, the figure was considerably high in Jammu and Kashmir with 77.14 per cent children below five years unable to get immunisation services," it added.

According to the study, in Jammu and Kashmir, nearly 35 per cent of the respondents said their children did not receive medical help during the lockdown, resulting in difficulties to cope with their children's illnesses and health hazards.

The study also talks about more systemic arrangements and logistical preparedness to ensure that children with no or compromised digital reach are not deprived from their Right to Education.

With online classes introduced as a substitute of schools during the lockdown, access to education for children remained a major issue of concern, as many of them, especially the ones from marginalised and financially poorer backgrounds found it difficult without smartphones and internet access.

The survey's findings revealed that nationally only 41 per cent households with children of school-going age could access online classes on a regular basis.

"Almost 90 per cent parents and primary caregivers reported that the lockdown has increased the screen time of their child to great or some extent. About half of the households recorded an increase of children's exposure to online activities during lockdown," it said.

The NGO said around 76 per cent parents agreed that they could keep a watch of their children's online activity to some extent.
