头热、发晕……99%以上是甲流！

近日，“甲流”“全国流感病毒阳性率快速上升”等话题登上热搜，不少网友纷纷表示自己出现了头热、发晕、喉咙痛等症状。

流感（influenza）是一种影响人类呼吸系统的病毒感染，自去年12月以来，流感病例一直在上升。

日前，中国疾控中心（Chinese Center for Disease Control and Prevention）发布《全国急性呼吸道传染病哨点监测情况（2024年第52周）》，分析显示：全国门急诊流感样病例的流感病毒阳性率较上周上升6.2%；不同省份间流感活动水平有所不同，北方省份上升略明显，但仍低于去年同期水平。

The positivity rate among people visiting hospitals with flu-like symptoms rose 6.2 percent during the week ending Dec 29 compared with the week before, according to data released earlier this month by the Chinese Center for Disease Control and Prevention. “The prevalence of flu in northern provinces is more severe, but the overall level is lower than what was seen during the same period of the last flu season,” said the China CDC.

近期，流感高发，据中国疾控中心最新数据，目前流感病毒阳性率 (positive rate) 持续上升，其中99%以上为甲流，流行株以A（H1N1）pdm09亚型为主。

Official data showed that the influenza A virus is responsible for more than 99 percent of positive flu cases nationwide. For the week ending Dec 29, about 99.7 percent of flu patients were infected by the strain. strain /streɪn/ 种类

甲型流感是什么？

甲型流感，简称“甲流”，是由甲型流感病毒引起的急性呼吸道传染病。甲流传染性强、容易发生变异，常导致大范围流行，几乎每次流感大流行都是由甲型流感病毒引起，且发病季节特征明显。

Influenza A, commonly known as "flu A", is an acute respiratory infectious disease caused by the influenza A virus. It is highly contagious, prone to mutation, being the major cause of widespread outbreaks. Almost every influenza pandemic has been caused by the influenza A virus, with a distinct seasonal pattern of onset. acute respiratory infectious disease 急性呼吸道感染病 contagious /kənˈteɪdʒəs/ （疾病）接触性传染的 mutation /mjuːˈteɪʃn/ 突变，变异 pandemic /pænˈdemɪk/ （正式）大流行病 seasonal pattern 季节性特征 onset /ˈɒnset/ （尤指某种坏事情的）开始，发作

患者的典型症状包括为高烧、头痛、乏力，且伴有全身肌肉酸痛等。尽管甲流有一定自限性，但容易引起其他并发症，包括肺炎、中耳炎、心肌炎、脑膜炎等严重并发症。

Typical symptoms include high fever, headache, fatigue, often followed by muscle aches. Although Influenza A has a certain self-limiting nature, it can lead to other complications, including severe conditions such as pneumonia, otitis media, myocarditis, and meningitis. fatigue /fəˈtiːɡ/ 乏力 complication /ˌkɒmplɪˈkeɪʃ(ə)n/ 并发症 pneumonia /njuːˈməʊniə/ 肺炎 otitis media /əʊˈtaɪtɪs/ 中耳炎 myocarditis /ˌmaɪəʊkɑːˈdaɪtɪs/ 心肌炎 meningitis /ˌmenɪnˈdʒaɪtɪs/ 脑膜炎

与之相比，普通感冒则是由鼻病毒等多种病原体导致，传染性弱，发病没有明显的季节特征，症状表现为鼻塞、流涕、喷嚏、咳嗽等，一般不发热或仅有低热，没有全身性症状，5至7天即可自愈，很少有并发症出现。

In common cases, it does not cause fever or only result in a low-grade fever, with no systemic symptoms.

抗流感药物速福达：神药还是误解？

随着流感感染人数增多，抗流感药物的销售量也持续攀升，其中，一种名为速福达（玛巴洛沙韦）(baloxavir marboxil)的药物引发了抢购热潮，甚至有药店定价高达300元。由于只需一次服药即可快速缓解流感症状，速福达被不少人称为“抗流感神药”。

The drug baloxavir marboxil, sold under the brand name Xofluza, is approved for use among adults, as well as children age 5 and above. While the original market price per strip of Xofluza, comprising two 20 milligram tablets, is 222 yuan ($30) in China, the prescription drug is currently being sold at over 300 yuan on some e-commerce platforms.

然而，这种药物是否适合所有人？它与传统流感用药奥司他韦有什么不同？对此，北京大学人民医院药学部药师孙博洋解释，奥司他韦和玛巴洛沙韦（速福达）同为抗病毒药物，目前均被证实可用于治疗甲型和乙型流感感染。由于两者作用机制不同，在用药方式上也有所区别：速福达只需一次服用即可完成整个疗程，而奥司他韦则需要每日服用两次，连续服用五天。

Speaking about the surging demand for Xofluza, Sun Boyang, a pharmacist at Peking University People's Hospital, said that compared with another common flu medication called oseltamivir, baloxavir marboxil is easier to administer. While oseltamivir—sold under the common brand name Tamiflu—is usually prescribed for five consecutive days, with a daily dosage of two tablets, Xofluza only needs to be administered once throughout the entire course of illness.

那么，什么时候服用抗病毒药物效果最好呢？来自首都医科大学附属北京儿童医院的王泉指出，由于流感病毒在体内复制速度快，建议在感染初期的48小时内用药，以获得最佳治疗效果。早确诊可以更早用药，从而更快缓解症状。

Wang Quan, a physician at Capital Medical University's Beijing Children's Hospital, said that any antiviral medication is most effective when administered within 48 hours of a confirmed infection.

针对部分家长自行购药给孩子服用的情况，孙博洋提醒，婴幼儿感染后应优先就医，在医生指导下合理用药。此外，对于妊娠期和哺乳期患者，用药安全问题也需格外注意。同时，抗病毒药物并不能直接缓解发烧、头痛等已出现的流感症状，因此服药后仍需采取对症治疗的方法。

As some concerned parents are stocking up on the relatively newer antiviral medication in anticipation of a drug shortage, Sun said that children infected with the flu virus should first be taken to a hospital for evaluation, and Xofluza should be administered only under professional guidance. Pregnant or lactating women should also take special precautions while using this antiviral medication, the pharmacist added. lactating /ˈlækteɪtɪŋ/ 哺乳的 precautions /prɪˈkɔːʃ(ə)n/ 预防措施 antiviral medication /ˌæntiˈvaɪrəl/ 抗病毒药物
