Objective

To analyze the epidemiological characteristics of influenza in Hubei from 2020 to 2024 and provide scientific evidence for subsequent prevention and control measures.

Methods

Using epidemiological history and clinical case data from the China CDC Information System, we analyzed influenza characteristics in Hubei during 2020 and 2024. Count data were compared using χ2 tests.

Results

Hubei reported 1 050 819 influenza cases (609 699 cases in 2023, 58.02%), including 377 576 influenza A (35.93%), 99 676 influenza B (9.49%), and 840 parainfluenza cases (0.08%). Influenza A predominated (χ2=530 018.166, P<0.001). Male cases (564 464, 53.72%) slightly outnumbered females (486 355, 46.28%) (χ2=5 806.006, P<0.001). Seasonal distribution showed winter (463 932 cases) > spring (376 247) > autumn (127 067) > summer (83 573) (χ2=395 402.793, P<0.001). Children aged 0 to 9 years were most affected (549 181 cases, χ2=1 358 132.202, P<0.001). Students (410 818 cases) and kindergarten children (193 027) showed highest incidence (χ2=8 079 748.599, P<0.001). Wuhan reported most cases (368 397), followed by Yichang (105 119)(χ2=2 800 000.000, P<0.001).

Conclusion

Influenza in Hubei exhibited distinct seasonality (winter-spring peaks), with 2023 seeing highest incidence. Children under 10 remain most vulnerable, warranting focused prevention in schools and childcare settings.

目的

分析湖北省2020-2024年流行性感冒(简称流感)的流行病学特征,为后续流感防控提供科学依据。

方法

基于2020-2024年中国疾病预防控制信息系统中湖北省流感患者的流行病学史、临床诊断个案数据,计数资料比较采用χ2检验,分析其流行病学特征。

结果

2020-2024年湖北省共报告流感1 050 819例(2023年报告流感609 699例,比率58.02%),其中甲型流感377 576例(35.93%),乙型流感99 676例(比率9.49%),副流感840例(比率0.08%),甲型流感比率高于乙型流感和副流感(χ2=530 018.166,P<0.001);2020-2024年湖北省报告流感男性564 464例(比率53.72%),女性486 355例(比率46.28%),差异无统计学意义(χ2=5 806.006,P<0.001);2020-2024年湖北省春季、夏季、秋季和冬季分别报告流感376 247、83 573、127 067和463 932例,发病比率为冬季>春季>秋季>夏季(χ2=395 402.793,P<0.001),不同月份发病比率差异有统计学意义(χ2=1 188 650.113,P<0.001);2020-2024年湖北省不同年龄段流感发病比率差异有统计学意义(χ2=1 358 132.202,P<0.001),高发年龄为0~9岁(549 181例);2020-2024年湖北省报告流感学生比率最高,为410 818例,其次为幼托儿童,193 027例,不同人群发病比率差异有统计学意义(χ2= 8 079 748.599,P<0.001);2020-2024年湖北省武汉市报告流感比率最高,为368 397例,其次为宜昌市,105 119例,不同城市流感发病比率比较差异有统计学意义(χ2=2 800 000.000,P<0.001)。

结论

2020-2024年湖北省流感流行具有明显季节性,冬季和春季高发,2023年发病最多,0~9岁易发病,防治对象应重点关注儿童,加强对学校和托幼机构的防控力度。

目的

分析湖北省2020-2024年流行性感冒(简称流感)的流行病学特征,为后续流感防控提供科学依据。

方法

基于2020-2024年中国疾病预防控制信息系统中湖北省流感患者的流行病学史、临床诊断个案数据,计数资料比较采用χ2检验,分析其流行病学特征。

结果

2020-2024年湖北省共报告流感1 050 819例(2023年报告流感609 699例,比率58.02%),其中甲型流感377 576例(35.93%),乙型流感99 676例(比率9.49%),副流感840例(比率0.08%),甲型流感比率高于乙型流感和副流感(χ2=530 018.166,P<0.001);2020-2024年湖北省报告流感男性564 464例(比率53.72%),女性486 355例(比率46.28%),差异无统计学意义(χ2=5 806.006,P<0.001);2020-2024年湖北省春季、夏季、秋季和冬季分别报告流感376 247、83 573、127 067和463 932例,发病比率为冬季>春季>秋季>夏季(χ2=395 402.793,P<0.001),不同月份发病比率差异有统计学意义(χ2=1 188 650.113,P<0.001);2020-2024年湖北省不同年龄段流感发病比率差异有统计学意义(χ2=1 358 132.202,P<0.001),高发年龄为0~9岁(549 181例);2020-2024年湖北省报告流感学生比率最高,为410 818例,其次为幼托儿童,193 027例,不同人群发病比率差异有统计学意义(χ2= 8 079 748.599,P<0.001);2020-2024年湖北省武汉市报告流感比率最高,为368 397例,其次为宜昌市,105 119例,不同城市流感发病比率比较差异有统计学意义(χ2=2 800 000.000,P<0.001)。

结论

2020-2024年湖北省流感流行具有明显季节性,冬季和春季高发,2023年发病最多,0~9岁易发病,防治对象应重点关注儿童,加强对学校和托幼机构的防控力度。

Objective

To analyze the epidemiological characteristics of influenza in Hubei from 2020 to 2024 and provide scientific evidence for subsequent prevention and control measures.

Methods

Using epidemiological history and clinical case data from the China CDC Information System, we analyzed influenza characteristics in Hubei during 2020 and 2024. Count data were compared using χ2 tests.

Results

Hubei reported 1 050 819 influenza cases (609 699 cases in 2023, 58.02%), including 377 576 influenza A (35.93%), 99 676 influenza B (9.49%), and 840 parainfluenza cases (0.08%). Influenza A predominated (χ2=530 018.166, P<0.001). Male cases (564 464, 53.72%) slightly outnumbered females (486 355, 46.28%) (χ2=5 806.006, P<0.001). Seasonal distribution showed winter (463 932 cases) > spring (376 247) > autumn (127 067) > summer (83 573) (χ2=395 402.793, P<0.001). Children aged 0 to 9 years were most affected (549 181 cases, χ2=1 358 132.202, P<0.001). Students (410 818 cases) and kindergarten children (193 027) showed highest incidence (χ2=8 079 748.599, P<0.001). Wuhan reported most cases (368 397), followed by Yichang (105 119)(χ2=2 800 000.000, P<0.001).

Conclusion

Influenza in Hubei exhibited distinct seasonality (winter-spring peaks), with 2023 seeing highest incidence. Children under 10 remain most vulnerable, warranting focused prevention in schools and childcare settings.

流行性感冒(简称流感)是由流感病毒引起的一种急性呼吸道传染病[1],主要通过飞沫传播,也可通过接触被病毒污染的物品传播[2-4]。流感病毒属于正黏病毒科,分为甲、乙、丙和丁型,其中,甲型和乙型流感病毒是引起人类季节性流感的主要病原体。流感的临床特征包括突发咳嗽、咽痛、高热、肌肉酸痛、头痛、乏力等,部分患者可能发展为肺炎、心肌炎等严重并发症,尤其是老年人、儿童、孕妇及慢性病患者等高危人群[5-6]。每年全球季节性流感感染人数估计在10亿左右,其中重症病例约300万~500万,死亡人数约29万~65万,流感发病率和死亡率在不同地区存在显著差异,发展中国家和医疗资源有限的地区通常负担更重[7-8]。流感的流行病学特征表现为季节性流行,通常在冬季和春季高发,但也可能发生全球性大流行[9-10]。我国不同地区流感的流行病学特征差异较大[11]。本研究对2020—2024年湖北省流感病例的流行病学特征进行分析,为后续流感防控提供科学依据。
从中国疾病预防控制信息系统收集湖北省流感监测资料、临床诊断病例个案,人口学特征数据来源于湖北统计年鉴。
筛选现住址为湖北省、审核日期为2020年1月1日—2024年12月31日、传染病报告卡审核状态为“已终审卡”的临床诊断流感病例;年龄范围为全人群;整理报告卡信息,包括性别、年龄、时间分布、人群分布和地区分布等情况。
采用SPSS 26.0软件和Excel 2020对收集数据进行整理分析,计数资料采用例数和频率描述,比较采用χ2检验,根据中国气象网将季节划分为四季:3—5月为春季,6—8月为夏季,9—11月为秋季,12—次年2月为冬季。按照年龄将研究对象分为7个年龄段:0~9、10~19、20~29、30~39、40~49、50~59和≥60岁。双侧检验水准α=0.05。
2020-2024年湖北省共报告流感1 050 819例,其中甲型流感377 576例(比率35.93%),乙型流感99 676例(比率9.49%),副流感840例(比率0.08%),甲型流感比率高于乙型流感和副流感(χ2=530 018.166,P<0.001);2023年流感发病例数显著高于2020-2022和2024年(χ2=1 040 106.800, P<0.001)。见表1
2020-2024年湖北省春季、夏季、秋季和冬季分别报告流感376 247、83 573、127 067和463 932例,发病比率为冬季>春季>秋季>夏季(χ2=395 402.793,P<0.001),2022年夏季为全年发病高峰。2020-2024年不同月份发病比率差异有统计学意义(χ2=1 188 650.113,P<0.001)。见表23
2020-2024年湖北省流感发病性别比例(男性vs.女性)为1.16∶1.00(564 464∶486 355),差异有统计学意义(χ2=5 806.006,P<0.001)。2020-2024年流感高发年龄为0~9岁,报告发病549 181例,占总报告发病例数的52.26%,40~59岁报告发病最少,为74 225例,占总报告发病例数的7.06%,不同年龄段流感发病比率比较差异有统计学意义(χ2=1 358 132.202,P<0.001)。2020-2024年湖北省流感学生累积发病最多,为410 818例,占总报告发病例数的39.10%;其次为幼托儿童,累积发病193 027例,占总报告发病例数的18.37%;散居儿童的累积发病例数位居第三,为154 617例,占总报告发病例数的14.71%。不同人群发病比率比较差异有统计学意义(χ2=8 079 748.599,P<0.001)。见表45
2020-2024年湖北省报告流感病例地区分布涉及23个城市,56个县(区)。武汉市累积报告发病例数最多,为368 397例,占总报告发病例数的35.06%;其次为宜昌市,报告发病105 119例,占总报告发病例数的10.00%;排第三位的城市为黄冈市,报告发病90 726例,占总报告发病例数的8.63%;湖北省不同城市流感发病例数比较差异有统计学意义(χ2=2 800 000.000,P<0.001)。见表6
流感是一种由流感病毒引起的急性呼吸道传染病,对人类健康和社会经济造成严重危害。流感病毒具有高度变异性,可能通过基因重组或突变产生新型病毒株,导致全球大流行[12]。1918年西班牙流感全球约5 000万人死亡[13];1957年亚洲流感全球约100万人死亡[14];2009年H1N1流感全球约15万人死亡[15]。虽然多数流感具有自限性,但其并发症可能会对患者健康造成长期影响。
本研究结果表明,2020-2024年湖北省共报告流感1 050 819例,2023年报告流感比率(58.02%)最高,每年依次为86 050、33 174、100 903、609 699和220 993例。2009-2019年湖北省流感疫情资料显示,流感发病例数先下降,然后上升,2009年为15 444例,下降至2010年的1 994例,再上升至2019年的274 611例[16]。2020-2022年湖北省流感每年发病例数远低于2019年,与COVID-19疫情期间切断传染源、传播途径,在个人防护、社交距离、健康监测、疫苗接种、环境卫生、减少聚集、增强体质、信息共享和宣传教育及国际旅行防控等方面采取严格防控措施[17-19]有关。
研究表明,不同时期流感类型发病情况与该地区温度、湿度和蒸汽压密切相关,温度和相对湿度对流感传播的影响可能很复杂,潮湿和炎热的夏天可能会促进甲型流感的患病率,但降低乙型流感的传播[20]。2018年1-3月从广州收集了9 914例流感患者鼻拭子,有2 547例(25.7%)流感病毒呈阳性,其中312例(3.1%)被鉴定为甲型流感,2 241例(22.6%)被鉴定为乙型流感[21]。本研究结果表明,2020-2024年湖北省共报告甲型流感377 576例(比率35.9%)、乙型流感99 676例(比率9.49%),甲型流感vs.乙型流感为3.79∶1.00。湖北省位于中国中部,属于南方地区,亚热带季风气候,夏季高温多雨,冬季温和少雨,整体气候较为温和,湿度较高[16],明确湖北省流感类型分布及其比例可为选择接种疫苗种类提供重要依据。
在时间分布特征方面,2020-2024年湖北省流感发病比率为冬季>春季>秋季>夏季,3月和12月常出现发病高峰,9月最低,2022年夏季为全年发病高峰。2020-2024年湖北省流感发病主要集中在春季和冬季,季节特征明显;2023年流感月发病例数较其他年份显著升高,2020-2024年不同月份发病比率有差异。
由于不同地区流感活动出现反弹,季节性分布发生变化,一些地区在夏季(非常规流感季节)出现了流感小高峰,可能与病毒传播模式变化和人群免疫功能降低[22]有关。本研究中2022年湖北省夏季就出现了全年流感高峰。
在人群分布特征方面,2020-2024年湖北省流感发病性别比例(男性vs.女性)为1.16∶1.00(564 464∶486 355),男性易感,与全国流感性别发病分布情况基本一致[23]。研究表明,雌激素可能增强免疫反应,而睾酮可能抑制免疫反应,男性对流感病毒的抵抗力弱于女性[24-25]。另外男性健康意识和预防措施不足、职业暴露风险较高、心理因素导致症状报告更频繁、进化生物学差异等[26-28]可能也是男性流感发病高于女性的原因。本研究中2020-2024年湖北省流感高发年龄为0~9岁,40~59岁报告发病最少;学生累积发病最多,其次为幼托儿童,散居儿童的累积发病例数位居第三。分析原因:(1)儿童和学生的免疫系统尚未完全发育,对流感病毒抵抗力较弱,易感染[29];(2)容易通过飞沫和接触传播,学校和幼儿园是典型的群体聚集场所[30];(3)儿童和学生卫生意识相对较弱,增加病毒传播风险[31];(4)儿童和学生缺乏感染或免疫记忆,更易感染新变异流感病毒株[32]
在空间分布特征方面,2020-2024年湖北省报告流感病例地区分布涉及23个城市,56个县(区)。武汉市累积报告发病例数最多,为368 397例,占总报告发病例数的35.06%;其次为宜昌市,报告发病105 119例,占总报告发病例数的10.00%;排第三位的城市为黄冈市,报告发病90 726例,占总报告发病例数的8.63%。受医疗资源分布、人口密度等因素影响,湖北省不同地市流感发病情况有所不同。其他地市,如宜昌、黄冈等地,流感发病率较往年也有所下降,整体发病分布情况与2009-2019年基本相似[16]
综上所述,2020-2024年湖北省流感流行具有明显季节性,冬季和春季高发,2023年发病最多,0~9岁易发病,防治对象应重点关注儿童,加强对学校和托幼机构的防控力度。
