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.

If india gives him same punishment then assume that india is developed, in india criminals are given more respect than the victims.
Insane person. why dont you give him similar punishment....
Leave Bihar Campaign :)
Is controlling criminals important or fighting against Modi important? Nitish and KC Tyagi, please tell us
Shameless act from a political goonda. BTW had it been a BJP politician's son, CD would have had BJP in the headline. No I am not condoning the act if it was a BJP politician's son involved, I am just talking about how biased this channel is.
if the leader in the SUV was a BJP leader, your headline would have screamed the word BJP. Bajrangi RSS etc!
That politician's son is going to be get caught and will soon be released without facing any punishment.
that's how it happens in India!!!
in case of BJP politician, headline would have been ' BJP politician shoots 19 year old boy'. Since crime is committed by a non BJP politician, it only says politician in hearing.
This how the journalists manipulate the news.
Biharis Deserves... who voted corrupt Goonda Rajya
CM Nithish Kumar is in Kerala, he want the Kerala to be made same like Bihar.
Nitish Kumar is busy trying to cobble up a coalition in his desperate attempt to become the PM of this country. Meanwhile, the state is ruled by Lalu and his sons. So the jungle raj continues in Bihar.
its time to make bihar, up, wb ,delhi and kerala as independent nations. kick all these aholes from rest of india, let them solve their civility issue themselves.
gutter people
THERE IS TOTAL JUNGLE RAJ PREVAILING IN BIHAR SINCE LAST 25 YEARS DURING RJD- JD(U) MISRULE. NITISH KUMAR IS RUNNING GOVT WITH HELP OF CORRUPT MEDIAS WHO ARE GETTING HUGE MONEY I.E. HUNDREDS OF CRORES PER ANNUM FROM JD(U) GOVT FOR FLASHING ROSY PICTURE OF CORRUPT AND WORST NITISH GOVT. LALOO HAS RETURNED REIGN OF TERROR IN STATE WHERE HIS COMMUNITY IS INDULGED IN MASS ANTI-NATIONAL ACTIVITIES LIKE NAXALISM, MURDERS, DACOITIES, KIDNAPPING ETC. THIS IS BEYOND CAPACITY OF CM TO CONTROL IT. SO PEOPLE OF BIHAR IS BOUND TO SUFFER FOR ELECTING CORRUPT AND WORST PERFORMING GOVT WHEN THERE WILL BE NO PEACE AND PROSPERITY.
