在H3N2的驱动下,美国和加拿大的流感病例激增,住院人数和死亡人数都很高,特别是在未接种疫苗的儿童中。 Flu cases surge in U.S. and Canada, driven by H3N2, with high hospitalizations and deaths, especially among unvaccinated children.

加拿大和美国的流感病例都在急剧上升,加拿大报告说,流感测试阳性率为27.7%,是H3N2、H1N1和流感B菌株,特别是H3N2驱动的三个季节中最高的。 Flu cases are rising sharply in both Canada and the U.S., with Canada reporting a 27.7% flu test positivity rate—the highest in three seasons—driven by H3N2, H1N1, and influenza B strains, especially H3N2. 在美国,记录了460多万例流感疾病,有49,000人住院,1,900人死亡;A(H3N2)A(H3N2)分片K变体降低了疫苗的效用,占病例的90%。 In the U.S., over 4.6 million flu illnesses have been recorded, with 49,000 hospitalizations and 1,900 deaths; the A(H3N2) subclade K variant, which reduces vaccine effectiveness, accounts for 90% of cases. 由于儿童接种疫苗的比率仍然很低,这个季节的儿科流感死亡人数已达3人,这是相关趋势的一部分。 Pediatric flu deaths have reached three this season, part of a concerning trend, as vaccination rates among children remain low. 这两个国家的卫生官员都强调接种疫苗还不算太晚, 因为流感仍有助于预防严重后果, 特别是对于高危人群而言。 Health officials in both countries stress it’s not too late to get vaccinated, as the flu shot still helps prevent severe outcomes, especially for high-risk groups.
