Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said the newly identified swine flu, called G4, is something we need to keep an eye on.
Speaking before a hearing by the Senate Assistance Committee, Fauci said that the Chinese have identified a virus – in the environment in the last week or so – that has not yet shown infection to humans, but it is showing the possibility of recombination.
Fauci explained that when several different strains of viruses infect the same host, such as pigs, they can exchange genetic information.
When they all mix and they contain certain factors that can make them easily transmitted to humans, you're always able to have another type of swine flu like we had in 2009, Mr. Fa Fai said.
Fauci said, G4 is still in the testing phase – Exceeding It is not called, an immediate threat.
But that's what we need to pay attention to just the way we did in 2009 with the arrival of swine flu, he said.
The G4 virus, which originated from the 2009 H1N1 swine flu pandemic, was described in a study published in the Proceedings of the National Academy of Sciences on Monday.
