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.

Nothing to say ! Everything is in the name of Dargha fights route cause is Un-Islamic.
Wrong people of the RIGHT-RELIGION.
Desecrating grave and Ullal Kazi khoora Thangal and SSF electing a rowdy who spending night at bar as Darga president against majority wishes
these two example enough for how low people can go for Darga business
lock down darga to save people from hell fire
really inhuman incident. must be hanged whoever made this crime.
These people trying to take advantage of Minister's patience. May Almighty Allah rest in peace his parents. Aameen
either minister or common people , writings on graves , building permanent structures not allowed in islam, muslims should avoid it... people can not show their anger by destroying such things, or degrading graves... only fools and ignorant muslims only can do such things... those fighting for power, should understand that you are fighting for unlawful money , dargha itself is un islamic thing for muslims... Prophet Muhammed (pbuh) ordered to destroy such dargahs, muslims also follow that way only...
what UT Khader did now, this people fighting for dargah's president ship. and damaging ut khader's parents graves is different issue.
as Monu Borkala said,
the above incident clearly says Dargah business is very profitable and it does not have any islamic background, and i must say that for money this type of people will kill anybody and do above incident further,
inhuman can do this crime. totally i must say its wrong. for all of us parents means its like a god to us, for the memory we build their grave, it feels like they are with us, damaging grave is like playing with emotions.
Whoever did this job is highly condemnable at the same time being a well wisher of U.T.Khader we are expecting our Minister to act fairly in the trouble unfolding in Ullal dargah. He is taking wrong side by siding with SSF people against the wishes of people of Ullal. It was clear by recent election to Dargah Committee majority of 27 out of 49 members elected a president instead of supporting people verdict sending government official of waqf at mid night to lock the Dargah chamber is highly condemnable.
UT Khader's big Fan, this must be a work of SDPI, if dog bark on the street let them bark, we should not think about it.
khader sir we are with you, whatever damage they have done to you the same in other way they will go through it.
Dont worry khader bhai, not a big deal to build a newer one. let this dogs go to the hell.
sad news, whatever the issue is touching someone's grave is totally wrong. i can proudly shout \humanity lost\"."
the above incident clearly says Dargah business is very profitable and it does not have any islamic background
catch those mad dogs and grave them in road.
UT khader's father was a great man he sacrificed so much to the society. this is clearly a horrible violence.
this is totally wrong, the politician or common man. should not touch the grave of the parents, some mad dogs did this
Devotees? These are humans with the worst order. And they want to take iver management of a dargah... obviously for corrupt purpose. #Shame
