Spokesperson of the World Health Organization Christian Lindmeyer has declared that the WHO will read the Chinese study on a new swine flu carefully, RIA Novosti reports.

Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study in the US science journal PNAS, although experts said there is no imminent threat.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.
