The 2016/2017 epidemic season was characterized by a lower number of diagnostically tested samples of the nasal and throat swabs and bronchoalveolar lavage fluid, compared with the preceding season. The predominant influenza subtype found was A/H3N2/ which was notably diagnosed in patients over 25 years of age. This subtype was also often diagnosed in older people of 65+ years, which is in line with the risk assessment prepared by the European Center for Disease Prevention and Control (ECDC) at the beginning of the season. The A/H3N2/ subtype was most often diagnosed in the West Pomeranian and Warmian-Masurian Voivodeships. In this epidemic season, there were 11 coinfections of the A/H3N2/ subtype with other influenza and influenza-like viruses recorded in Poland. A different situation had occurred in the 2014/2015 season, when the subtype A/H3N2/ also was predominant, but the virus was most commonly diagnosed in children up to 14 years of age. In both seasons, the least confirmations were observed in patients between 15 and 24 years.
2016/2017 流感季节与前一个季节相比，用于诊断检测的鼻拭子和咽拭子以及支气管肺泡灌洗液样本数量较少。发现的主要流感亚型为 A/H3N2/，主要诊断于 25 岁以上的患者。这种亚型也经常在 65 岁以上的老年人中诊断出来，这与欧洲疾病预防控制中心（ECDC）在季节开始时的风险评估相符。A/H3N2/亚型在西波美拉尼亚省和瓦尔米亚-马祖里省被诊断出的次数最多。在本流感季节，波兰记录了 11 例 A/H3N2/亚型与其他流感和类流感病毒的合并感染。在 2014/2015 季节情况则有所不同，当时 A/H3N2/亚型也占主导地位，但该病毒主要在 14 岁以下的儿童中诊断。在这两个季节中，在 15 至 24 岁的患者中观察到的确认病例最少。
