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.

Dont live your life with HATE in your heart for anyone,
You will end up hurting yourself more than the people you HATE
Dear Brothers.
There is no God but ALLAH and Muhammad pbuh is the last and final messenger of ALLAH. ALLAH guides the one who is HONEST in knowing the TRUTH.
The Prophets of ALLAH are many but 25 Prophets are mentioned in QURAN by name.The best of them are 5
Prophet Noah,
Prophet Abraham,
Prophet Moses,
Prophet Jesus and
Prophet Muhammad - Peace be upon them all.
Mankind needs Guidance from their teachings... They all conveyed that ALLAH is the creator of all that exists (human beings, animals, plants, earth, universe and all that is in between them) and we all should WORSHIP him alone without associating partners.
Everyone is born as a Muslim but their parents take them to worship different man made objects as Gods... which is a Sin. (Until U research on it, You will never understand the consequences on worshiping others beside the True God)
Come to the TRUTH... and use your intellect to know the reality with LOGIC And REASON ---- QURAN invites YOU to use this logic and REASON & compare it with Bible, vedas and other scriptures... PLease TRY to read QURAN (TheQuranproject online)without being bias.
These people are jealous that they cannot attract/convert anybody from other community.....Islam is the best religion....one Allah....one prophet...thank Allah--- am a muslim....
these people can sell ramayana and mahabharatha nobody will come to object
These goons are afraid of people finding truth .and leaving the baseless religion....
