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.

The actual FACT is during Independence and Partition of India & Pakistan, British as usual left a piece of land so that there will be no peace between India & Pakistan (in-case if they join Hands they will become Super Power of the World). The only solution for Peace to Prevail is leave Kashmir to their people. Let them decide which part of Kashmir they want to stay, make partition, I know this won't be done as for political GAINS, Let the families of Politician start living in Kashmir and feel how it is to lose a loved ones. Just by blaming Pundits and Muslims wont work. Killing innocent people by either side is just to brainwash the Public and to keep the rivalry alive on the basis of religion and country.
Malala , you have yourself experienced how inhuman and ruthlessly atrocious Pakistan Government is. As they manipulated you and your family’s circumstances to harass, they are exploiting and manipulating India’s freeness and all-inclusiveness to keep Kashmir and its denizens in constant turmoil to get pleasure from other’s pain. They are doing same to Baluchistanis since partition and the Kashmiries of Pakistan held area are extremely unhappy and are in totters due to this policy of Pakistan.
Its Pakistan's fault not Indians....Pakistan should stop sending terrorists to India ...which is not happening at all....that is why Kashmiris suffering around there...
Malala should advise Pakistan government first not to involve with our domestic problems....
It is good for Kashmiris if they stay with India as far as their security and economic developments are concerned...
True that Malala has suffered beyond our imagination and came out of it bravely. But that doesn't make her an expert in everything.
Dear Malala, Can you please talk about the inhumanity and heartbreak in Pakistan-occupied Balochistan?
Malala Request you to please stay peaceful and stay happy and not say things that don't fit into ur vocab pls.
I didn't really used to like her but now my respect for her has gone up a lot.
Do you live in delusional world..what should paramilitary forces do if someone is breaking law and order of any country
Lets hope this time her voice will be heard as she has won Noble Prize for PEACE. Lets wish that India will keep Human Life above her EGO and will look Kashmir with HUMAN eye before there is no solution left
Dear Malala, Surely New Delhi government and Kashmiri people need to work together. Your concern is respected.
India in committing a genocide in Kashmir by killing innocent people SC must take notice of this.
As much as I admire Malala, I hate to see her get into Politics and Indo-Pak disputes. There are enough noises being made, or have been made, to no end.
please advise the kids to stop pelting stones and focus on studies to snatch the opportunities from rapidly growing Indian economy.
Thank you Malala for raising your voice in our support.
Since you are an influential opinion maker, I hope the world listen to you and stop the perpetrator from committing these atrocities against us.
Malalaji, Welcome to politics.
Dear Malala we respect you. But it is not government of India or Pakistan decide the future of Kashmir. There are some third parties who really want disturbance or conflict in the valley.
Trolls across the border always loved everything Malala spoke about. I hope they do the same now and accept stark reality!
Thank You Malala, for your kind words and care about Kashmiris
She is a teenage girl with little understanding of the dynamics of terrorism inspite of being a victim of it herself. The valley has been infected by the terror virus with religion which drove away the natural inhabitants of Pandits from Kashmir being hounded from mosque sermons. Many got murdered and not so lucky to escape. No one thought of their rights, now a generation has spent the life as refugee. Neither India nor local Kashmir government or the world body cares to it. However Pakistan terror export looks working well, but it is always the civilian who pays the price.
