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.

Dears even if prophet (pbuh) did not ate beef ,never deneyed it to his rollovers ,what is halal and what is haram is clearly mentioned in Quran, but for a beliver its not compelsory to eat beef to prove his belief it permisable one like mutton and chicken or veg it depends upon the place, whether, biographical condition ,ect, here not only Muslims meeting beef people of,so many other religion also eating but only Hindus worshiping it this is fact ,,one more thing people of different parts of the world eetind beef since human eyes but problem begins only it created a vote bank ,,now real Hindus should prove what is real hinduism which permits to kill human for the name of cow? Still cow know nothing!!

Dear CD
Don't support by publishing un islamic topic from so called Muslim (Nawzbillah)
Beware of such people,
Our bellowed prophet peace be upon him, said anybody who lies as misquoting against him, shall reserve their place in hell.
We should ask him for authenticated proof, sure he will fail to do so, then people have to decide his fate on the grounds of sharia law.
Better change your name to Tarak Mehta :-)
Hello, who is this Tarek Fatah, Agent of RSS, what he know about Prophet Swallahu Alaihi wa sallim. Where is quoted beef is Haram in Qur'an or Hadith.
What he is talking even not veda, purana, ramayana or in Mahabharatha there is no single word against slaughtering cow. 10000 of cows and other animal slaughter in yaaga, yajna.
Prophet Muhammed peace be upon him Told be aware of MUNAFIQs like you . and also mentioned that the day will come when Ignorant will become leaders ......so you try to become......you are going against ISLAM by claiming something Haram when its allowed in ISLAM
May be one day you will say PIG also allowed....!!!
