The distribution of influenza A subtypes was studied in specimens recovered from patients in long-term care facility (LTCF) outbreaks and in non-LTCF outbreaks in Alberta, Canada, for 3 years before the influenza pandemic of 2009. We found that H3 but not H1 was associated with infection in older adults. Therefore, H3 was more commonly found than H1 in outbreaks in LTCFs.
在加拿大艾伯塔省，我们对 2009 年流感大流行前 3 年长期护理机构（LTCF）爆发和非 LTCF 爆发的患者样本中流感 A 亚型的分布进行了研究。我们发现，与老年人感染相关的是 H3 而不是 H1。因此，H3 在 LTCF 爆发中比 H1 更常见。
