泰国医科学局：10月流感阳性样本九成以上为甲型H1N1，未发现奥司他韦耐药突变
曼谷—泰国卫生部医科学局 11 月 5 日公布流感病毒监测结果：今年 1 月至 10 月，泰国国家流感中心共检测送检样本 8,734 份，其中 1,278 份检出流感病毒，阳性率 14.63%；检出最多的是甲型 H1N1（pdm09）704 份，占 55.09%，其次是甲型 H3N2 的 306 份与乙型 Victoria 谱系的 268 份。
单看 10 月：581 份样本中 122 份阳性，阳性率 21%，其中甲型 H1N1 占 115 份、占阳性样本的 94.26%，成为当月绝对主导毒株。其亚分支 6B.1A.5a.2a.1 自今年 6 月起占比明显上升。
耐药监测方面，医科学局对神经氨酸酶基因的分析显示，1 月至 10 月未检出与奥司他韦耐药相关的 H275Y 突变，也未发现其他与抗病毒药物敏感性降低相关的突变；10 月专门就耐药性分析的 127 份样本同样未见耐药突变。医科学局局长 Adisorn Wattanasak 呼吁公众继续保持个人卫生防护。
另据泰国疾病控制局的数据，今年 1 月 1 日至 10 月 17 日全国报告流感病例 543,385 例，报告数高于过去五年同期中位数，仍处警戒水平。

Thailand's Medical Sciences Department: Over 90% of October Flu-Positive Samples Were A(H1N1), With No Oseltamivir-Resistance Mutation Found
BANGKOK — Thailand's Department of Medical Sciences announced its influenza surveillance results on November 5. From January to October, the Thai National Influenza Center tested 8,734 samples, of which 1,278 were positive for influenza, a positivity rate of 14.63%. Influenza A(H1N1)pdm09 was the most common strain with 704 samples, or 55.09%, followed by A(H3N2) with 306 and influenza B/Victoria with 268.
In October alone, 122 of 581 samples were positive, a rate of 21%, and 115 of those, or 94.26% of positive samples, were A(H1N1), making it the month's overwhelmingly dominant strain. Its subclade 6B.1A.5a.2a.1 has risen markedly since June.
On drug resistance, the department's neuraminidase gene analysis found no H275Y mutation, which is associated with oseltamivir resistance, and no other mutations linked to reduced antiviral susceptibility in the January-to-October samples; 127 samples analyzed for resistance in October likewise showed none. Director-General Adisorn Wattanasak urged the public to maintain personal hygiene precautions.
Separately, Thailand's Department of Disease Control reported 543,385 influenza cases nationwide from January 1 to October 17, above the median for the same period over the past five years, keeping the situation at an alert level.
