Eye on Dalits, PM Modi launches Bhim pay app

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 15: Union Health Minister Harsh Vardhan has appealed to all states and Union Territories to ban the sale of smokeless tobacco products and spitting in public places in line with the orders of the Rajasthan and Jharkhand governments to prevent the spread of coronavirus infection.

In a letter to all state health ministers, Vardhan said smokeless tobacco users have a tendency to spit in public places or otherwise and therefore, increase health risks especially those of spreading contagious diseases like COVID-19, tuberculosis, swine flu, encephalitis and others.

"Use of smokeless tobacco also creates an unhygienic environment which further spreads the diseases. The large gathering at the retail outlets where smokeless tobacco products are sold, also pose the risk of spread of COVID-19," he said.

In the letter dated May 11, the Union minister underlined that tobacco use is a major threat to public health globally. He also mentioned the Indian Council of Medical Research's (ICMR) appeal to the public not to consume and spit smokeless tobacco products in public places.

Chewing tobacco products and areca nut increases the production of saliva followed by a very strong urge to spit. Spitting in public places could enhance the spread of the COVID-19, Vardhan said.

"By banning spitting in public places, states and UTs can help in achieving not only Swachh Bharat but also Swasth Bharat (Clean India and Healthy India)," he said.

Vardhan also mentioned the May 1 guidelines issued by the Union Home Ministry under the National Disaster Management Act, 2005, which stipulate that "spitting in public places shall be punishable with fine as may be prescribed by the state/UT local authority and consumption of liquor, pan, gutkha, tobacco etc in public places is not allowed".

Appreciating the efforts of Rajasthan and Jharkhand in this direction, the Union Health Minister urged all states to take similar measures and create widespread awareness regarding the harm of spitting in public places.

The Rajasthan government had by an ordinance banned spinning in public places and sale of paan, gutka and tobacco in the wake of the coronavirus outbreak. The Jharkhand too has imposed a complete ban on all types of tobacco products to prevent spitting in public places that could increase the spread of coronavirus infection.

"I am happy to note that the governments of Jharkhand and Rajasthan have already completely banned the sale of tobacco products and spitting in public places. Therefore, I urge upon you to take similar measures and also create widespread awareness in your state/ UT regarding harms of spitting in public places.

"It is also requested that the directions of Ministry of Home Affairs in this regard may be implemented scrupulously and effectively," Vardhan said in the letter.

Tobacco smoking is a known risk factor for many respiratory infections and increases the severity of related diseases. A review of studies by public health experts convened by WHO on April 29 found that smokers are more likely to develop severe diseases, compared to non-smokers, said Binoy Mathew, senior programme officer of Voluntary Health Association of India.

It is one of the main risk factors for a number of chronic ailments, including cancer, lung and cardiovascular diseases, he said, adding that according to the Global Adult Tobacco Survey, with 268 million or 28.6 per cent of all adults in India, the country has the second largest number of tobacco users in the world.

At least 12 lakh die from tobacco-related diseases every year, Mathew said.

Those keen to quit smoking and smokeless products can avail of free of charge telephone-based services launched by the government. The Ministry of Health has set up a National Tobacco Quit Line Services to provide counselling services to help tobacco consumers quit the habit.
