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.

Shaji, Rich people have already got their black money in white before 8th November, they have been informed before hand by Feku....no one died from rich and other political parties..
Prime Minister Sab, what is happening.... people are dying...have mercy on them....
According ruling BJP, people will have to sacrifice for ache din and this is what happening. Ruling party is not worried about the daily deaths of people becoz all of them are from poor family whereas rich people are relaxing since they got the money exchanged in advacne of the declaration. I think bjp is not feeling shame for running Govt on the dead bodies and they feel proud of these deaths telling this is a sacrifice for bright future of India. None of the people who has black money every stood in the que. BJP leaders received new currency in advance. I dont know how many more poor people will have to die before the situation becomes normal. shamelsss govt is still justifying their decision. Mukhtar Abbas is actign as if he is an agent of Devil.
Insane Modi Bhakts like Naren might be happy after reading this news.
According to Bhakta\s they are sacrificing their lives for the country.
