Covid-19: Government warns against use of N-95 masks with valved respirator

New Delhi, April 7: The government continued to take steps to contain the spread of coronavirus including a strategy of cluster containment as the cases continued to rise and Tuesday saw single-day largest jump of 722 positive cases.

The total number of positive cases reached 4,789 on Tuesday, the 14th day of lockdown.

According to the latest update of the Health Ministry, there are 4,312 active cases, 352 persons have been cured or discharged (one migrated) and 124 have died.

Maharashtra has the largest number of positive cases at 868 and also accounts for the largest number of deaths at 48. Tamil Nadu has 621 confirmed cases.

Thirteen persons have died in Madhya Pradesh and the same number in Gujarat.
The 21-day lockdown was announced on March 24 by Prime Minister Narendra Modi.

At the regular media briefing at 4 pm, Lav Aggarwal, Joint Secretary in the Health Ministry, said that the government is adopting a strategy for cluster containment.

"This strategy is producing positive results, especially in Agra, Gautam Buddh Nagar, Pathanamthitta, Bhilwara and East Delhi," he said.

Aggarwal said that a recent study by the Indian Council of Medical Research (ICMR) has shown that a person infected with coronavirus can infect 406 others in just 30 days if he does not follow the lockdown and social distancing norms.

He said no decision has been taken on extending the lockdown and urged against any speculation.

He said latest technology was being used for management of COVID-19 and there was real-time tracking of ambulances.

The official said the dedicated facilities for COVID-19 are divided into three parts -- COVID Care Centre, Dedicated COVID Health Centre and Dedicated COVID Hospitals.

He said that COVID Care Centres were for treating mild, very mild and likely to be COVID-19 patients. Hostels, hotels, school, and stadium can be used for this. "We have asked states to map it with COVID Care Hospitals and COVID Health Centre so that patients can be shifted if needed," he said.

The official said that COVID Health Centres were for treating COVID-19 patients of clinically moderate level of seriousness. "For this, fully functional hospitals will be used. A dedicated block of a fully functional hospital can also be used for this. The hospitals must have beds with oxygen support," he said.

Aggarwal said that dedicated COVID Hospitals were meant for severe and critical cases and these must be fully-equipped with ICUs and ventilators.
New coronavirus cases were reported on Tuesday from several states including Maharashtra, Madhya Pradesh, West Bengal, and Tamil Nadu.

The Ministry of Environment, Forest and Climate Change has issued an advisory about containing coronavirus in national parks, sanctuaries and tiger reserves in view of the spread of COVID-19 and a report about tiger being infected in New York. The Central Zoo Authority has also advised zoos in India to remain on high alert.

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.
