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.

I don't know why alvas is doing like this.....in the sense all alvas student know that there is not one room in alvas which number starts from 13....and each alvas pu student know the story behind this.....but i can't understand whether it is true or false........because i'm student of alvas.
The reason of suicide is not due to warden harassment, of course to control the students wardens should be strict. Student has very bad habit of stealing the things of other friends and she caught several times. Warden might have warned her for her bad things. So took this step. She is very bad in her due record she was not paying the school fees, whenever she get money she spend the money for lavish life and in case of shortfall she steal money from other roommates also she is going other rooms and stealing the things from students. I know all these matters because she stolen from daughter's mobile also. Later when her cupboard checked all stolen things came out such as expensive mobiles, sandals, perfumes, cosmetics, jackets and Money. Please let me know anybody will tolerate this bad habit in any college.
