A pandemic (H1N1) 2009 virus strain carrying the D222G mutation was identified in a severely ill man and was transmitted to a household contact. Only mild illness developed in the contact, despite his obesity and diabetes. The isolated virus reacted fully with an antiserum against the pandemic vaccine strain.
一种携带 D222G 突变的 2009 年甲型 H1N1 流感病毒株在一名重症患者中被检出,并传播给了一名家庭接触者。尽管接触者肥胖且患有糖尿病,但仅出现轻微疾病。分离出的病毒与针对大流行疫苗株的抗血清完全反应。
