Mangaluru: 100-bed Sharada Ayurveda Hospital inaugurated

Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

Mysuru, Mar 13: A state-of-the-art viral research laboratory in the city has been identified as one of the testing laboratories for the detection of COVID-19, official sources said here on Friday.

The samples of suspected cases could be sent to the lab for analysis and it would take about three hours to get the results.

The Viral Research and Diagnostic Laboratory (VRDL), which was set up from Central grants and functions at the Microbiology Department of K.R. Hospital, has been authorised to carry out the tests. This lab in Mysuru is among the 52-plus laboratories in the country.

Though the VRDL is equipped to carry out the tests, the sole authority of confirming the virus lies with the Indian Council of Medical Research (ICMR)-National Institute of Virology (NIV) in Pune. VRDL is also the sole agency for collection and transportation of suspected samples of COVID-19 to NIV.

VRDL, which is part of the Mysore Medical College and Research Institute, functions on the advice of NIV.

According to the guidelines issued by ICMR, the results of the tests done here have to be shared with NIV the same day and the labs are not supposed to disclose the results since the NIV is the only authority to declare positive cases. Also, confirmation from the NIV should be awaited in case the samples test negative for COVID-19. The ICMR, in the guidelines made available on its website, has advised clinicians at labs to isolate the patient tested positive for COVID-19 in the identified facility and follow bio-safety precautions.

VRDL is a part of a network of labs established by the Department of Health Research, Government of India. The rise in the number of viral outbreaks and the resultant mortality had been cited as key reasons for the launch of network of such hi-tech labs in the country.

The NIV and the National Centre for Disease Control, Delhi, are the top laboratories for the network, while the National Institute of Epidemiology, Chennai, is the supervising authority for the data generated by the network of labs, sources added.

Bengaluru, Jun 22: The opening of Schools in the state, is unlikely before Dasara festival, as a majority of the parents are averse to send their children due to the COVID-19 scare.

According to official sources, in the State education department, a majority of parents, who were asked to give their opinion on re-opening of schools in the state, have reportedly favoured continuing the closing of schools till September.

The primary and Secondary education department had received feedback from various stakeholders including educational institutions, parents and Teachers, clocking high towards not opening the schools for the 2020-21 academic year till Dasara days.
