Maintain integrity, sincerity: Mangalore varsity VC tells lawyers

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.

Bengaluru, Mar 6: The Karnataka government has directed school authorities to grant leave to students and staff suffering from cold or fever in the light of renewed coronavirus (COVID -19) fears.

"If any student, teacher of staff is suffering from respiratory infections, they should be granted leave. They should be allowed to come back to school only after confirming from the doctor that they are cured. In case of a student or staff staying at hostels developing any symptoms, they should be kept in a separate room," said the government circular.

"Tests are also being conducting on passengers arriving in Karnataka and all precautionary measures are being taken," said Sriramulu about the 40,000 people thermal screened at the Kempegowda International Airport (KIA) in the city. Major private hospitals in the city have geared up to treat suspected cases.

"We are observing 461 people for Coronavirus symptoms at their residences, however, no positive case has emerged from Karnataka," said state Health Department's Joint Director, Communicable Diseases, Prakash Kumar.

The five people under isolated observation at Rajiv Gandhi Institute of Chest Diseases continue to be so on Thursday as well. As many as 273 samples sent from the state for coronavirus testing reported negative.

In Karnataka, 68,717 passengers have been thermal-screened for the virus until now at Kempegowda International Airport in the city and Mangluru International Airport.

Another 5,103 passengers were also checked for the virus at Karwar and Mangluru seaports.

On Thursday, 16 people completed the mandatory 28-day observation period while a total of 225 people also underwent the same.

Karnataka is screening all international passengers and the state health department met the private sector hospitals to take stock of recent developments.
