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.

Muslim organisations felicitate State BJP Chief Nalin Kumar
I want to know from them wat was the need for this. Has this helped the ordinary Mangalore Muslims in anyway. I would not have asked abt this if the program was conducted in your house. But here it is done in the name of Muslims. We need to stop being intellectually dishonest
Young energetic Muslim brothers present in Dk ,please note we need young leaders to lead us . Wake up ... and take over .
We respect ur decision sir.
But there are a lot of questions about it on people's mind.
We need to be updated about ur next plan of action.
Are u planning to approach the court for gaining the permission from the police, bcoz otherwise I don't think we will get the permission
Secondly, a few days back I wanted to contact Muslim central committee office to confirm if the protest Wil be there. I googled for the no, but the no. did not exist. Does that mean the Muslim central committee does not have an office or telephone no????
This only shows how organised we are.
Requesting Muslim central committee to get their house in order. Get more professional. Also consult people to utilise various platform to responsibly collect funds from so many ordinary bearys who want to donate money, but don't know whom to send it to.
We need an action committee to handle such situations. It must consist a battery of lawyers to fight the cases filed by the police.
If our leaders are old, they need to groom new leaders into the committee.
Moreover, it is important to question these so called leaders about their fecilitation program conducted for making kateel wen he won the election. Wat was the purpose of such fecilitation. Becoz I don't think he gives a damn when our community suffered. I question, whether all this is done in our name only to gain your contact and flourish ur business???
Never ever dare to do so in the name of Muslims
