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.

Do you know who start the tippu jayanthi dear
This is the fact, a party built on corrupt ideology will not survive. The entire nation will know the truth.
What is their moral value of these guys who killed that person who sacrificed his whole life for the nation. What can we expect from these people. Until the past few years they were agreeing TIPU SULTAN as the best ruler, tiger of Mysore, and the man who taught to resist the invaders.
Just for the personal benefits, the same guys portray him negatively
People of such a mentality should be catalgorized as sick and mentally distorted group who should not be considered fit for election or make any policitical party.
The wise people should boycott such immoral party, Support the fair and the reliable party. If not available go for the least corrupt party.
Eddi is the only CM who spent his life in jail for corruption (not as a freedom fighter)
Think of our future geneations and our children,
God help our country from these corrupt group.
