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. Anant K. Hegde is criminal and communal minded person, who can't tolerate the coexistence of people of different religions and castes in Kannada Nadu. Whatever the "guilty feeling" he has in his mind due to his own communal mind, he expressed it on Siddaramaih. He was already awarded with Ministerial Berth for his anti-Islam & anti-Muslim rhetoric and now he is using his "communal card" to divide the people. He may be promised to be conferred with "CM" post for this.
This is what he is now being trained by his "Saffron".
Mr. Hegde's statement is absolutely incorrect. Mr. Hegde is communal minded, so he likes communization in the country particularly in Karnataka and Mr. Siddaramiay likes peace and all religions are same there is no discrimination.
This speech should not be surprising for us. Whenever BJP feels they are in danger of loosing election or peopels support they start to take support of pakistan name. Now every indian knows BJP is the only benificiary of taking name of pakistan may be for that purpuse our prime minister went there and hugged him for supporoting him. BJP politics has gone too much cheap. GOd save our country.
