An allergy occurs when an individual's immune system misclassifies typically harmless substances as harmful and has a specific and reproducible immune response (1,2). The severity of allergy symptoms can range from itchy, watery eyes and hives to life-threatening anaphylaxis, and the presence of allergies can negatively impact an individual's quality of life (3-6). This report uses 2021 National Health Interview Survey (NHIS) data to describe the prevalence of seasonal allergies, eczema, and food allergies in adults in the United States.
当个体的免疫系统将通常无害的物质误分类为有害物质并产生特定且可重复的免疫反应时，就会发生过敏（1,2）。过敏症状的严重程度从眼睛瘙痒、流泪和出现荨麻疹到危及生命的过敏反应不等，过敏的存在会对个体的生活质量产生负面影响（3 - 6）。本报告使用2021年美国国家健康访谈调查（NHIS）的数据来描述美国成年人中季节性过敏、湿疹和食物过敏的患病率。
