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.

With all due respects, to all our brothern Hindus,
One thing sure, series of babas because who are not allowed to marry are indulged in rape, adultary cases.
Babas who called Godman became criminals.
Hindus should not be so stupid to allow these babas to commit more crime and spoil the name of Hinduism.
If you dont allow them, you are risking your daughters in a very dangererous state. May God really help.
why are the hording in hindi, do this people not respect kannada and kannadigas?
@Hari... In that matter, Kerala media did well. They didnt give much importance to Amit Shah's visit. Kerala media covered actor Dileep issue at that time. But cunning Shah brought national pro cheddi media there for his programmes
They are coming for spreading hatred and communal thinking.. should avoid them and should not attend thier programmes. Even media should not cover thier arrival with much importance
LOL... Yogi and Shah from the state, which has no sufficient toilets for people and they are talking about development... Greeeeaaaaat
Communal Yogi and shahspoiled Mangaluru' sacredness
I heard speech of Yogi, while he visited Kerala. Fool Yogi told Kerala govt to learn hospital treatments and life care from UP hospitals... See the irony - Yogi, who is the reason for death of 61 children ask to learn from hospital things to Kerala govt, where health care sector having no. 1 position among Indian states
Mangaluru was sacred place just before your arrival. You spoiled that with blood stains of 61 children and many raped women
See the face of swamis, really public are idiots
Sacred land with feku babas... Yogi better concentrate on your UP land. First try to develop your UP then give advice to others. Our manglore is developing and we do not need your advise. Try to correct law and order in your state. I wonder why you became CM.. Instead of that you could have become a sadhu or pandith. This will be good and suitable for you. Also try to learn the meaning of DEVELOPMENT!!!!
