The UN’s World Health Organization recently said China was being hit with influenza B.  On February 8, officials with the Chinese National Influenza Center said their research shows the current flu B is still preventable with flu shots.

Officials said that the current B strain has not mutated to a drug resistant form. They also said that the number of cases in China are at “acceptable” levels.

Influenza B affects humans and seals, and is not in the same family as influenza A (which includes swine flu).
