流感(flu)是“influenza”的縮寫,指由流感病毒引起的急性呼吸道傳染病。流感病毒屬于正黏液病毒科,分為甲(A)、乙(B)、丙(C)、丁(D)四種類型,其中甲型和乙型病毒是導緻人類季節性流感的主要病原體。
傳播途徑與症狀
流感通過飛沫傳播(如咳嗽、打噴嚏)或接觸受污染物體表面傳播。典型症狀包括突發高熱(38℃以上)、肌肉酸痛、頭痛、幹咳、咽喉痛及乏力。部分患者可能出現嘔吐或腹瀉,嬰幼兒、老年人和慢性病患者感染後易發展為肺炎等并發症。
預防與治療
世界衛生組織建議每年接種流感疫苗,尤其是孕婦、65歲以上老年人和免疫系統較弱的高危人群。抗病毒藥物如奧司他韋(Oseltamivir)在發病48小時内使用可縮短病程。非藥物幹預措施包括佩戴口罩、勤洗手及避免密集場所。
流行病學特征
流感在全球呈季節性流行,北半球多發生于10月至次年5月。甲型流感病毒因易發生抗原變異,可能引發大範圍流行,例如1918年的“西班牙流感”和2009年的H1N1疫情。
