An outbreak of influenza caused by the A(H1N1) subtype in military recruits in February 1978 afforded an opportunity to study the association of ABO blood groups with influenza morbidity and serological response. Fifty-eight per cent of 336 recruits became clinically ill. There was no differential distribution of clinical influenza by blood group. However, seroconversion to a titre of greater than or equal to 20 was significantly and appreciably higher in groups A and B than O and AB. Also, among those with serologically confirmed clinical influenza, the occurrence was significantly higher in groups A and B than groups O and AB.
1978年2月，某部队新兵中爆发了由A（H1N1）亚型流感病毒引起的流感疫情，这为研究ABO血型与流感发病率及血清学反应之间的关联提供了契机。336名新兵中有58%出现了临床症状。不同血型的新兵患临床流感的分布没有差异。然而，A组和B组血清转化至滴度大于或等于20的比例显著高于O组和AB组。此外，在血清学确诊为临床流感的患者中，A组和B组的发病率也显著高于O组和AB组。
