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.

Haj subsidy was used to fleece the Muslim Pilgrims. I am sure the Haj tickets are much cheaper.
dear Hassan, dont bother yourself with airfare calcuations. This Naqwi is a stupid parallysed minister of BJP-RSS group. Though he has tongue but he cant speak his own, he has to be feeded by his superiors and spit the same. who the hell he to decide the number of piligrims to perform Hajj, is KSA is fathers property? he is thinking we Indian Muslims are stupid? i doubt he is a muslim (he is not). for your info, dont calculate airfare and expenses which is bound to occur during this holy deed. Islam has clearly emphasized "Hajj shall be performed for healthy and wealthy slaves" lets Ask Allah to all of us blesssed to reach that holy place and paerform our Hajj in sha Allah. Government subsidy is my foot....
He think he and his party fool people in each and every occations. What ever the quota saudi government provides, that much people will go to Hajj every year depend upon the Quota.
Record number of pilgrims ...without subsidy is a slap on you and Modi government.....
Mr mininster, We dont want Subsidy But please compare the air fare now and during HAj season. If you control on that then people will realise that you had did something positive. Airfare regular price from mumbai to jeddah is around Rs 25000/- But during Ramadan and Hajj seoson its crosses more then Rs 75000/- Differrence is more then what government was giving Susidy. So dont fool the nation. Keep control on Air fare. Jai hind
