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.

But BJP was able to do it in UP and Gujarat since EC is in its pocket
After model code of conduct came into existence in Karnataka, Congress crooks are not able to distribute money (both black money & fake currency) freely to get people for Pappu rallies like before.
Why can’t the idiot understand that Kannadigas have no interest in meeting him to listen to his nonsense.
Because it is a BJP stronghold and naturally communally sensitive region!
"Rahul asked party workers not to brag about their achievements and the
achievements of ministers, but to focus on key issues of each region
that ensure victory"
Is there anything to brag? And, he is advising to focus on key issues, now, during the election time? What were they doing for last 5 years?
Congress has change for its own good. Party party hierarchy, should be strong. The party must have zero tolerance on Corruption in the name of Party funds. Collect money from ministerial aspirants and Chairmen of statutory boards. Why other parties speak lightly about Congress is due to situation that is prevailing in the Congress. Native Congressmen are sidelined with migrated defected leaders. No one is listening or giving chances to hear views. This time Congress will learn a hard lesson for sidelining devout and loyal Congress leaders and giving prominence of migrants. Even senior leaders like Mr.Jaffar Sheriff and Moily are sidelined. Mr. S.M. Krishna left the party due to not giving importance to his seniority or experience. Now one after the other will start leaving the Congress after out come of the elections in Karnataka.
