警惕!甲型流感取代乙型流感,多地高发!

警惕!多地甲型流感已取代乙型流感,成当下高发流感类型。

警惕!多地甲型流感已取代乙型流感,成当下高发流感类型。

近期流感肆孽,各地流感病毒检测阳性率已达近年高峰水平,紧接着出现了医院儿科门诊一号难求、儿科医生病倒、幼儿园停课、“神药”断货.....

总之我们在朋友圈能看到的图片都是这样的:



或是这样的



但一波未平,一波又起!

警惕!多地流感病毒株已从乙型转向甲型

我们知道引起这次门诊大爆发的流感主要元凶就是乙型流感Yamagata系毒株,然而就当大家把大部分精力都集中在如何应对乙型病株的时候,又有多市疾控中心提示:“甲型流感已取代乙型流感成当下高发流感类型”:

浙江台州:

据台州晚报报道,浙江台州市疾控中心实验室每周都会对哨点医院采集的流感样病例标本进行相关检测和病例分离,监测结果显示,从2017年第45周开始,台州流感优势毒株由甲型H3N2型转变为乙型Yamagata型,并导致台州流感高发。

而近期,甲型H1N1型构成比逐渐增加,乙型Yamagata型比例逐渐下降。至2018年第3周,甲型H1N1占阳性标本的66.67%,已取代乙型Yamagata型成为当前流行的优势毒株。

浙江温州:

据温州日报瓯网消息,温州市疾控中心介绍,今年的流感发病水平,是近几年来流感活动强度最高的一年。2018年第3周(1月15日-21日),甲型H1N1流感检出比例占65.31%,为主要流行菌株,乙型Yamagata菌株检出比例呈下降趋势。

北京:

据北京日报报道,1月9日北京市疾控中心公布最新流感疫情监测情况。监测结果显示,北京市流感病毒活动度仍处于较高水平,且仍是乙型、甲型H1N1和甲型H3N2流感病毒共同流行。甲型H1N1病例数量开始增多,与乙型病毒共同占据较高比例。不过,每周报告的流感样病例增幅已有所下降。

河北:

据燕赵晚报消息,河北石家庄市疾控中心对外发布信息,1月1日至今,石市流感发病仍处在发病高峰,病例数较去年同期明显增加,目前,流感病毒优势株有从前阶段的乙型逐渐转变为新甲1型的趋势。

虽然,前段时间是以乙型流感病毒为主,但从近期各地疾控中心数据上来看,甲型流感有取代乙型流感发展成当下高发流感类型的趋势。

此前多年,季节性流感都是以甲型流感为主,所以这回对甲型流感要“卷土重来”的阵势,我们绝不能掉以轻心。

甲型与乙型流感的区别

那么甲型与乙型流感病毒的区别是什么呢?

能够导致人类流感的流感病毒分为甲、乙、丙三型。其中甲型和乙型流感病毒从形态和导致疾病特征上有些相像,而丙型流感病毒只引起人类不明显的或轻微的上呼吸道感染,很少造成流行。

简单来说,甲型H1N1流感虽然在人群的感染率相对较低,流感疫苗有良好保护作用,但相对乙型流感而言,甲型H1N1流感对个体的身体危害相对较重。

3月份可能出现新一波流感,基层医生要做准备!

近日,国家流感中心主任王大燕曾表示,总体上无论是南方省份还是北方省份,还是处于流感的一个高峰阶段,不能放松警惕。

1月17日下午,钟南山院士解读了今年流感特点,并提醒,今年3月份可能出现新一波流感。

预防流感最有效的措施是流感疫苗的接种,最重要的是,多地流感病株已从乙型转向甲型,而目前的三价疫苗是覆盖甲型H1N1病株。

目前使用的流感疫苗包含甲型H1N1、甲型H3N2和乙型Victoria株3个组分,接种一次可预防3种型别的流感。通常接种流感疫苗2周后,可产生具有保护水平的抗体。

流感往往有两个高峰,一个高峰为冬春季,另一个高峰则是夏季。所以现在接种流感疫苗,对于当前的流行高峰和接下来的夏季高峰都非常有用。

尽管盛行的流感病毒是个变色龙,总是变换来变换去,但根据全球流感监测数据显示,当前各型别流感病毒均未发生明显的变异,只是在乙型与甲型中不断转化比重。

优势毒株有变化, 流感病毒由乙型转为甲型不得不防!作为全面健康管理的基层医生更应该做好合理宣传,做好群众健康的守门人。

附:如何预防流感?

1. 注意个人卫生习惯,勤洗手,特别是饭前便后,触摸眼睛、鼻或口腔后,外出回家后;尽量用洗手液或肥皂、流动水洗净。

2. 保持环境清洁和通风,尽量减少到人员密集、空气污浊的场所。

3. 应尽量避免接触呼吸道感染患者,不得不接触时需做好个人防护,如佩戴口罩。家里有人感染流感,建议尽可能隔离,减少与孩子接触。

4. 根据气温变化为孩子增减衣物、平衡膳食、加强锻炼、保证睡眠,增强体质和免疫力。

5. 接种流感疫苗是最好的预防方法,除特殊情况(小于6个月、对鸡蛋过敏及其他不适合接种的疾病等),建议在流感季节来临前、在医务工作者指导下为孩子接种疫苗。

国家科技进步一等奖——甲型H1N1流感项目八大创新点

2014年度国家科技奖励大会1月9日在京举行。“我国首次对2009年甲型H1N1流感大流行有效防控及集成创新性研究”获国家科技进步一等奖。其8大创新点如下: 创新点1:是在国务院领导下,建立了由卫生部牵头,各部委参与的联防联控机制。以机制创新促进科技创新,以科技创新支撑疫情防控,使我国在人类历史上首次实现了对流感大流行的有效干预和控制。 创新点2:在国际上首先研制成功诊断试剂。获得了发明专利。

PLOS ONE:甲型流感病毒进化和传播规律研究获进展

甲型流感为急性呼吸道传染病,其病原体是一种新型的甲型H1N1流感病毒,在人群中传播。自2009年开始,甲型H1N1流感在全球范围内大规模流行。2010年8月,世卫组织宣布甲型H1N1流感大流行期已经结束。2012年我国甲型H1N1流感病例超过300例,由于流感病毒经常发生抗原漂移,因此经常发生规模大小不等的暴发流行。 中国科学院动物研究所何宏轩研究员领导的野生动物疫病研究组2009年在《科学

专家解疑:甲型H1N1流感是否卷土重来

事件: 近日有媒体报道,俄罗斯甲型H1N1流感发病率已经超出警戒线,达到疫情级别,截至1月27日已有超过107人死亡,疫情甚至已达“恐怖”级别。我国厦门市有关甲型H1N1流感的报道也见诸报端,称“流感流行强度有增强趋势,个别集体单位出现流感暴发”。 《中国科学报》记者查阅了世界卫生组织(WHO)1月26日发布的报告。报告显示流感活动在以色列、约旦、阿曼、巴基斯坦等一些西亚国家持续,北美

医学专家发现甲型流感重症易感基因干扰素诱导的跨膜蛋白-3基因

近日,记者从北京佑安医院采访获悉,佑安医院近日与英国牛津大学分子医学研究所合作研究发现,人体第11号染色体的某基因位点与人群感染甲型流感后易患重症密切相关。这一研究有助于早期发现甲型流感重症易患人群,若采取早期预防、干预措施,将能有效降低重症流感发生率,提高治愈率。 此项研究的牵头人北京佑安医院院长、北京市中西医结合传染病研究所所长李宁说,此基因位点称作“干扰素诱导的跨膜蛋白-3基因”。它的遗传

严密监控H7N9甲型流感病毒很重要

大量生物特征表明,H7N9甲型流感病毒对人类已构成重大威胁。本周《自然》杂志发表了新的数据,说明对H7N9甲型流感病毒进行严密监控的重要性。 与H5N1和H1N1病毒不同,H7N9病毒能够和人类受体结合,感染人类气管和肺部,并在细胞内自我复制,哪怕是支气管最末端的细胞。舒跃龙指出,双重受体结合与高增长速度使H7N9病毒更容易从鸟类传播到人类。然而,H7N9病毒在人类气管和肺部的自我复制能

Sci Rep:于广利课题组发现褐藻硫酸多糖KW抑制甲型流感病毒感染

甲型流感病毒(Influenza A Virus,IAV)属于正粘病毒科,是具有包膜的单股负链RNA病毒;根据其表面的血凝素蛋白(HA)和神经氨酸酶(NA)的结构及基因特性的不同可分为若干亚型,如H1N1, H3N2, H5N1及H7N9等。甲型流感病毒的爆发流行不仅给人类生命健康带来巨大威胁,还会带来巨大的经济损失。特别是H5N1和H7N9等高致病性禽流感病毒已跨越种属屏障引起人类感染并致感染者
