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, May 3: Karnataka Chief Minister BS Yediyurappa on Sunday said that his government has allowed labourers to travel to their hometowns in the state on KSRTC buses free of charge for three days starting on Sunday.

"Labourers have been allowed to travel in KSRTC buses free of charge from the district centres and capital Bengaluru to their hometowns in Karnataka for three days from today," Yediyurappa said.

"The government will bear the cost of travel. The concern is that a large number of labourers should not assemble at any bus stop," he added.

The Ministry of Home Affairs (MHA) on May 1, issued an order to extend the ongoing lockdown by two more weeks from May 4 and also allowed the movement of migrant workers, tourists, students and other persons stranded at different places, by special trains.

According to Deputy Commissioner Sindhu B Rupesh, all those who enter the district will be screened. Those who come from outside the district and state will be asked to remain in quarantine. 

As the relaxation is announced for 12 hours, the public should be cautious while venturing out of the house. Wearing a mask in public is mandatory in addition to maintaining social distance.
