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.

If Owaisi compains for jds and bsp, he will lose the respect what we kannadigas have in him. He is being used by these parties only to divide muslim votes and alternatively support bjp. In case Owaisi did so, it will be very clear that he is hidden agent of bjp. If actually he needs betterment of muslims, he should keep away from Karnakataka elections. |this is our sincere advice to Mr. Owaisi otherwise we will support or respect him any more. Besides this if he comes to karnataka, i reqeust muslims to welcome him by rotten eggs and black flags. Let him understand that this is not Hyderabad. Why is he showing double standard? Why cant he stand in one boat. He should not try to be another Mir Jafar or Mir Qasim. I was a fan of him, but if he comes to karnataka on the hidden agenda of bjp, i will disrespect him for ever and will not consider him as a sympathisers of Muslims. He will do it for his own benefit. In every speech he speaks about unity in Muslims but he himself is going against it. I doubt he will keep on his popularity and may lose next election in his own constituency and AIMIM will also be thrown out. Hope Owaisi will understand the situation and take back his plan to visit karnataka to divide muslim votes.
Mr. Owaisi, try to follow one ideology. Dont spread your leg in two boats at the same time, you may fall down
He only denied the campaign offer before. Now again..
Double Standard guy, we know about you and we know about your dealing With BJP president Amith Shah close door meeting , do not try to fool Kanndaigas , we are very clear whom to vote ...........
