Nearly a quarter of ethnic Chinese have a tiny genetic variant that boosts sixfold their risk of falling gravely ill when infected with flu, a study published yesterday said.
Less than one per cent of Caucasians are thought to have the gene alteration, which has previously been linked to severe influenza. Yet about 25 per cent of Chinese people have the gene variant, which is also common in Japanese and Korean people.
