Black money: SIT brings new intel agency on board

New Delhi, Apr 2: With 437 new cases reported in the last 24 hours, the tally of COVID-19 positive cases in India shot up to 1,834 on Wednesday night.

The number of deaths in the country due to COVID-19 has risen to 41.

The total number of active cases in the country is 1,649. 143 persons have been cured and discharged from the hospitals. One person has migrated, according to the data provided by the Ministry of Health and Family Welfare.

Earlier on Wednesday, Union Home Secretary Ajay Bhalla urged all state governments and Union Territory administrations to ensure the lockdown measures issued by the Ministry of Home Affairs are strictly implemented.

"All the state governments/UT administrations are requested to strictly implement the lockdown measures issued by MHA in the exercise of the powers under Disaster Management Act, 2005 in letter and spirit," Bhalla said.

Prime Minister Modi had earlier announced a 21-day lockdown in the entire country to deal with the spread of coronavirus, saying that "social distancing" is the only option to deal with the disease, which spreads rapidly.

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, Jan 24: Although India's Ujjwala programme encouraged adoption of liquefied petroleum gas (LPG) for cooking among the poor, households availing the scheme have not shifted away from using highly polluting fuels like firewood, a study reveals.

The researchers, including those from the University of British Columbia (UBC) in Canada, found that additional incentives to encourage regular use of cooking gas are necessary for a complete transition to clean cooking fuel among poor rural households.

They noted that about 2.9 billion people across Asia, Africa, and Latin America burn solid fuels like firewood to meet their cooking energy needs.

This has significant negative implications for public health, the environment, and societal development, according to the researchers.

Through the Pradhan Mantri Ujjwala Yojana (PMUY), India has provided capital cost subsidies to poor women to adopt a clean-burning cooking fuel or LPG.

The researchers explained that within the first 40 months of the scheme, more than 80 million households obtained LPG stoves.

However, the full benefits of LPG adoption depend on near complete replacement of polluting fuels with LPG, according to a research-based policy brief published in the journal Nature Energy.

The scientists said this cannot be assumed solely on the basis of LPG presence in the household.

"Our research shows that Ujjwala was able to attract new consumers rapidly, but those consumers did not start using LPG on a regular basis," Abhishek Kar, a postdoc at Columbia University in the US, told PTI.

The study analysed LPG sales data for over 25,000 consumers, including PMUY beneficiaries, as well as general rural LPG consumers in Koppal district of Karnataka.

The scientists employed data covering all LPG purchases of PMUY beneficiaries through their first year in the programme.

They also assessed the general rural population's purchases during their first five years as consumers to assess the effect of experience on use.

The findings estimate that an average rural family needs to purchase five 14.2 kilogramme-cylinders annually to meet half of their cooking needs.

However, the study said just seven per cent of PMUY beneficiaries in Koppal purchased five or more cylinders annually, suggesting that the beneficiaries seldom use LPG.

The general (nonPMUY) consumers in this region use on average two times more LPG cylinders than PMUY beneficiaries, the researchers noted.

Yet, only 45 per cent of nonPMUY consumers use five or more cylinders per year -- even after several years of experience with LPG, they said.

The team assessed price and seasonal factors affecting LPG use among the general population over a three-year period.

It found that LPG consumers are sensitive to price and seasonality -- LPG cylinder refill rates are lower in the summer when agricultural activity is limited, and cash is scarce.

"There was no scheme incentives to promote use, except general LPG subsidies which is available to all, including the urban middle class," said Kar, who was a Ph.D. scholar at UBC when the research was published.

"If there is no additional income, what cost would a poor family on an already tight budget cut to pay for an extra expense on a regular basis.

"Ujjwala has started the scheme of 5 kg-cylinder in response, but the impact of that on LPG sales is still publicly unknown," he said.

These findings, the researchers noted, suggest the need for additional measures to promote regular LPG use for all rural populations.

Although the finding come from a single district in Southern India, it may also apply to other areas with similar socio-economic conditions, they said.

A more expansive evaluation of PMUY would help design targeted incentives to transform infrequent users to regular users, according to the researchers.
