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 4: The government has not talked about charging anything from migrant labourers as 85 per cent of the transportation cost is borne by the railways and 15 per cent by state governments, the Centre said on Monday amid a row over the national transporter allegedly charging the workers for ferrying them home during the COVID-19-induced lockdown.

The government also said the process of transporting the stranded migrant labourers was being coordinated by states “except for one or two states”.

Asked if the migrant labourers were being charged for being ferried home, Joint Secretary at the Health Ministry Lav Agarwal said that as far as migrant labourers are concerned, the guidelines have clearly stated that under the infectious disease management one should stay where he or she is.

“Based on the request given from states for particular cases, permission was given to run special trains. Be it government of India or the Railways, we have not talked about charging from workers. Eighty-five per cent of the transportation cost is borne by the Railways, while states have to bear 15 per cent of the cost,” he told reporters.

“Based on the request of the states the process that started, under which limited number of stranded migrant labourers have to be transported for a particular reason, is being coordinated by the state governments, except for one or two states,” Agarwal said.

At the daily briefing on the COVID-19 situation, Agarwal also said that in the last 24 hours, 1,074 COVID-19 patients have recovered, the highest number of recoveries in one day.

The recovery rate stands at 27.52 per cent with 11,706 COVID-19 patients cured till now, he said.

Agarwal said in the last 24 hours, 2,553 novel coronavirus cases were reported, taking the number of overall cases to 42,533. The total number of active cases stands at 29,453, he said.

The joint secretary also said that the COVID-19 curve is relatively flat as of now and it was not right to talk in terms of when the peak would come.

“If we collectively work then the peak might not ever come, while if we fail in any way we might experience a spike in cases,” he said.

Amitabh Kant, Chairman of the Empowered Group dealing with civil society, NGOs, industries and international partners, said in 112 aspirational districts, “we worked with the collectors and in these 112 districts only 610 cases have been reported which is two per cent of the national level infection”.

In these 112 districts, 22 per cent of India's population resides, he said.

In a few districts like Baramulla, Nuh Rachi, Kupwara and Jaisalmer more than 30 cases have been reported, while in the rest of the places very few cases are there, Kant said.

New Delhi, May 5: India registered the biggest jump in numbers of COVID-19 cases and deaths, with 3,900 new cases and 195 deaths being reported in the last 24 hours, according to the Ministry of Health and Family Welfare on Tuesday.

"3,900 COVID-19 cases and 195 deaths have been reported in the last 24 hours, the largest spike till now in both," according to the Ministry of Health and Family Welfare.

The total number of confirmed coronavirus cases in India reached 46,433, including 1,568 deaths, according to the Union Ministry of Health and Family Welfare on Tuesday.

According to the latest update by the MoHFW, 12,727 patients in the country have been cured and discharged, or have migrated, as of today morning. At present, there are 32,138 active cases in the country.

Maharashtra with 14,541 cases is the worst-affected state by the disease, while Gujarat with 5,804 cases is second on the list.
