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.

Mr. Jayant is the senior most Justice in the country and as per seniority should have been made the Chief Justice of any High court. But as a reward for his honesty he is punished and victimised. Indian citizen lost their confidence in Legislature and Executive, now even Judiciary is under the clutches of Fascit forces. God save our Democracy & secular India.
You have to pay price of your honesty. But History will always remember you for your commitment
Politics politics... everywhere politics... it happen only in india
Merely because he is honest or independant judge does not mean that he is to be elevated according to his wishes.If he has resigned in protest against his transfer to Allahabad High Court than there should not be any uproar about it. He is a judge who is bound to render justice any where he is posted both honestly and independantly.
Sad to hear. One more victim of politics. In our country there is no SYSTEM in the POLITICS but there is POLITICS in all systems.
Transfer issue may be the reason. He might earned much so he dont want job anymore.. happy retirement
Why that much importance giving to him. He dont want to work so resigned. thats it
